The Fifth Plenary Session of the 19th CPC Central Committee proposed to speed up the construction of a new development pattern with the domestic big cycle as the main body and the domestic and international double cycles promoting each other. Domestic and foreign enterprises and international personages interviewed by this reporter believe that China, as the second largest economy in the world and the only major economy in the world that has achieved positive economic growth this year, actively building a new development pattern and promoting reform and opening up at a higher starting point will promote the steady recovery and growth of the global economy.

　　"Further enhance the resilience and vitality of China’s economy"

　　In recent years, China’s economy has been transformed into a big domestic cycle. The ratio of current account surplus to GDP has dropped from 9.9% in 2007 to less than 1% now, and the contribution rate of domestic demand to economic growth has exceeded 100% in seven years. In the coming period, the characteristics of China’s domestic market leading the national economic cycle will be more obvious, and the domestic demand potential of economic growth will be continuously released.

　　On the pencil production line of Longhui Stationery Co., Ltd. in Matou Town Industrial Park, jin an district, Lu ‘an City, Anhui Province, a series of processes are orderly, such as planing rod, rubber core, painting, printing and packaging. The company has an annual output of more than 300 million pencils, which are exported to more than 20 countries in Southeast Asia, Europe and America. Affected by the epidemic, the company’s export orders fell by about 30% in the first half of this year. Zhu Xingjia, the person in charge of the company, introduced that with the assistance of the local government, the company vigorously explored the domestic market and created a new brand "Liuzhou" pencil. At present, domestic sales have accounted for 40% of the company’s total sales, making up for the gap in the decline in export orders, and the output has been improved.

　　In Tonghai County, Yuxi City, the largest vegetable production base in Yunnan Province, Yunnan Huantai Import and Export Co., Ltd. actively uses e-commerce platform to expand the domestic market and find new growth points when foreign trade is facing difficulties. "We imported Vietnamese mangoes, Thai mangosteen, durian, longan, etc. and sold them to the domestic market. The benefits are very good." Kong Xiangping, general manager of the company, said that the company is planning to shift to intensive processing of vegetable products, and has attracted 1 million US dollars of foreign investment, which will be used to purchase equipment and rebuild processing workshops. "Make good use of the domestic and foreign markets, and we are full of confidence in the future development."

　　Vincent, honorary vice president of Belgian Zeebrugge Port Authority, said that the share of China’s consumer market in the global consumer market is growing day by day, and generate, a high-end consumer market, has strong purchasing power. China will actively build a new development pattern and cultivate a more mature consumer market, which will stimulate greater consumption potential. "The rapid development of e-commerce in China and the upgrading of domestic consumption promote the growth of cross-border business, providing a broader market for foreign enterprises and bringing great development opportunities to the world economy."

　　"Giving full play to the potential of domestic demand and better connecting the domestic market with the international market will further enhance the resilience and vitality of China’s economy." Enrique Fanjul, a former Spanish embassy in business counselor, said that the growing middle-income groups in China will further promote consumption upgrading and inject more impetus into economic development.

　　"Opened a more open door for foreign investors"

　　The new development pattern is by no means a closed domestic cycle, but an open domestic and international dual cycle. China’s position in the world economy will continue to rise, its ties with the world economy will be closer, and its market opportunities for other countries will be broader, making it a huge gravitational field for attracting international commodities and factor resources.

　　Multinational companies have said that they will continue to be optimistic about the China market, and their long-term business development strategy in China has not changed. According to the statistics of the Ministry of Commerce of China, from January to July this year, 18,838 foreign enterprises were newly established in China. From January to November, China actually used 899.38 billion yuan of foreign capital, a year-on-year increase of 6.3%.

　　Many multinational companies continue to increase their investment in China, and some large projects continue to land. Uniqlo, a world-renowned clothing brand, recently opened 19 new stores in 18 cities in China, accelerating its entry into the second, third and fourth tier cities in China; German pharmaceutical company Boehringer Ingelheim launched the Innovation Cooperation Center in Shanghai, saying that it will increase its capital in China by 450 million euros in the next five years; NEC invested 100 billion yen to build a new factory in China … … "The accelerated deployment of foreign companies in China shows that foreign investors have confidence in the China market. China is still a hot spot for global investment. " Vincent said.

　　"As GM’s largest market and global innovation center, China market is the key to realize the company’s vision." Mary Bola, Chairman and CEO of General Motors, said that GM sold 1.466 million vehicles worldwide in the second quarter, of which 713,600 vehicles were sold in China, accounting for more than 48% of the total global sales. "The China market is of strategic significance to GM, and we will continue to increase investment in technology and other fields in the future." Bai Li, global executive vice president of GM and president of GM China, said.

　　Axel Goethals, director of the Institute of Asian Affairs of the European Union, said that speeding up the construction of a new development pattern with the domestic macro-cycle as the main body and the domestic and international dual-cycle promoting each other is an important measure for China to further reform and open up, "opening the door for foreign investors, creating more opportunities and promoting the high-quality development of an open world economy".

　　"Based on the new stage of development, China has accelerated the construction of a new development pattern and adapted to the new changes in the international situation, which is of great significance to the economic development of China and the world." Professor Akiguchi Yosuke of the Department of Economics at Teijing University said that China’s continuous opening-up to the outside world, by improving the business environment and expanding foreign capital market access, will promote the mutual promotion of foreign trade and domestic market, which will bring more impetus and opportunities for the development of the world economy.

　　"Enterprises from all countries will enjoy more China development dividends."

　　Since the beginning of this year, the foreign investment law and its implementing regulations have been fully implemented, and the negative list of foreign investment access has been further reduced; Release and implementation of the overall plan for the expansion of the pilot free trade zone and the construction of Hainan free trade port … … A series of concrete measures have fully proved that the open door of China will not be closed, but will only grow wider and wider.

　　"In recent years, our cooperation with our partners in China has been very smooth, and the company has developed faster and faster." Zhu Lewen, manager of Thailand ZFB Import and Export Company, said: "With the further expansion of China’s opening to the outside world, we are full of confidence in China’s market prospects."

　　"The business environment in China is becoming more and more transparent and fair, and enterprises from all countries will enjoy more China development dividends." Vincent said that the epidemic has dealt a blow to the global shipping industry, and the shipping trade between China and Zeebrugge Port has not been interrupted. "China is a staunch supporter of economic globalization and free trade. As China accelerates the construction of a new development pattern, China will lead the recovery and development of the world economy."

　　Goethals said that in recent years, the business environment in China has been increasingly optimized, and the supply chain of the industrial chain has been moving towards the high end. The continuous upgrading of China’s consumer market and the increasing demand for high-quality products from other countries will provide important impetus for the recovery and development of the world economy.

　　"For Japanese companies, there are diverse and huge business opportunities in the China market." Keiyuki Sekou, research director of Canon Global Strategy Institute, said that Toyota, Matsushita Electric and Hitachi are expanding their business in China. I hope that Japanese business leaders will visit China more often, experience the rapidly developing China market for themselves, and formulate appropriate development strategies, which will surely reap more dividends.

　　Fanjul said that China is a staunch defender and active practitioner of multilateralism and believes that China will bring more opportunities for world economic recovery and development in the post-epidemic era.

On the afternoon of September 12th, the new M7 from AITO was officially launched and delivered.

Yu Chengdong said that the new model has been fully upgraded with an investment of 750 million yuan, with stronger body, chassis and performance, brand-new space design and layout, and smarter driving system and cockpit.

The new M7 in Wenjie has launched five models, with the price range of RMB249,800 to RMB329,800. This price adjustment has lowered M7 by 40,000 yuan compared with the price reduction in January. The starting price of the new car is 70 thousand yuan lower than the previous version.

The appearance of the new M7 continues the design features of the previous generation, especially the front part, which adopts a brand-new low wind resistance design. After a small adjustment, the front face presents a three-layer air intake grille design, which makes the whole front face look more layered.

In addition, the high-profile model of the five-seat version of the M7 is also equipped with a laser radar, and the HUAWEI ADS 2.0 advanced intelligent driving system is applied, which further improves the driving experience and safety performance.

As a medium and large SUV, the new M7 has a body size of 5020mm (length) x 1945mm (width) x 1760mm (height) and a wheelbase of 2820mm. In addition to fine-tuning the height of the car body, other aspects are completely consistent with the current models.

The interior style of the new M7 keeps a minimalist design, and the steering wheel color is fine-tuned to keep consistent with the overall interior color. Equipped with a 10.25-inch curved LCD instrument panel and a 15.6-inch central control panel, the center console and door panel are made of high-quality micro-velvet material, and the overall material is upgraded to a higher level, which enhances the quality of the interior.

HarmonyOS Intelligent Cockpit 3.0 is also a highlight of the new M7. Brand-new theme design, adding a variety of exquisite screen savers, adding a lot of color to the interior space. With the addition of the super desktop function, the connection of mobile terminal applications in HarmonyOS becomes more convenient, and the user’s mobile phone interconnection experience is improved.

Even in the case of poor signal, Xiaoyi Voice Assistant can provide offline voice navigation function, which ensures a convenient use experience in all situations.

The high-end version is equipped with HUAWEI ADS 2.0 advanced intelligent driving system, which is equipped with overhead lidar, 3 millimeter-wave radars, 11 high-definition visual perception cameras and 12 ultrasonic radars with 27 sensing hardware.

Through these super hardware configurations, the M7 can realize intelligent driving on expressways and urban areas without relying on high-precision maps. It is expected that the NCA in the urban area will be "open all over the country" in December this year.

In addition, the system has realized the omnidirectional and lateral anti-collision ability, and the maximum braking speed of AEB (automatic emergency braking) has increased to 90 km/h. In addition, the system also supports parking service and ultra-narrow parking spaces, which provides more convenience for drivers.

The new M7 has undergone all-round body structure and safety upgrade, and adopted submarine-grade high-strength steel and CBS composite body material to realize the cage body design. The submarine-grade hot-formed steel accounts for 24.4% of the whole vehicle, which can bear 17 tons per square centimeter.

The proportion of high-strength steel and aluminum alloy in the whole vehicle is as high as 80.6%. These upgrading measures have greatly improved the structural safety of the car body and provided higher safety guarantee for passengers.

The five-seat version of the new M7 fits the hot spot in the market, with ample space in the second row, and the seat comfort is further improved. Ventilation, heating and massage functions have become standard for four seats, greatly improving the enjoyment of riding. The rear air conditioning control panel is updated with intuitive LCD touch, which is more convenient to operate and provides passengers with a more intelligent ride experience.

MagLink interface has been added in the back row, which can supplement Huawei’s flat panels and support suspension through the official docking station. Passengers in the back row can use two Huawei flat panels at the same time, realizing the convenient function of multi-device linkage. This design takes into account the use of multiple devices and improves the intelligent interconnection experience in the car.

The new M7 is excellent in space, with a standard trunk volume of 686L, which can easily accommodate 12 20-inch boarding boxes.

If the two rows of seats are laid down and connected with the trunk, the maximum loading space can be expanded to 1619L, which is enough to accommodate 30 20-inch trunks. This design takes into account the practical needs when traveling and carrying a large number of items.

The five-seat version has 29 storage spaces, and a 52L compartment is specially designed to fully consider the storage of valuables.

In terms of power, the new M7 is equipped with HUAWEI DriveONE extended-range electric drive platform, equipped with a 1.5T engine and a maximum power of 112kW. The four-wheel drive version has a 100-kilometer acceleration of 4.8 seconds, a pure battery life of 240km and a comprehensive battery life of 1300km. In addition, the fuel consumption is as low as 5.6L/100km under the feed condition.

In order to improve driving performance, the new M7 has upgraded the HUAWEID ATSTM 2.0 dynamic adaptive torque system, and at the same time, the front and rear suspension double FSD variable damping shock absorbers have also been optimized, making the driving experience smoother.

The new model M7 has introduced five versions, obviously targeting the competitors of the ideal L7. M7 takes advantage of more cost-effective price and leading intelligent driving technology.

However, its design has been controversial in the past. Despite a lot of internal upgrades, there is no obvious change in appearance. Compared with the ideal L7, it lacks some sense of technology and luxury, which may be the place that M7 needs to improve.

Although it is "far ahead" in intelligent driving, the M5 intelligent driving version launched this year has not significantly improved the overall sales performance of the industry. This year, the average monthly sales volume of the two models in the world is only about 5,000, which is far from the ideal monthly sales volume of 30,000+. We can still look forward to whether the new M7 can be recognized by the market when it goes on the market!

AMD has previously released 24-core and 32-core third-generation thread ripper products, 3960X and 3970X, which have swept all the fever-grade product lines of Intel.

Like the strategy of mainstream consumer products online, after the 12-core R9 3900X, the 16-core R9 3950X was released. AMD seemed to think that it was not enough, so it launched the bloody version of TR3 3990X, with an unprecedented 64-core 128 thread.

Today, I will bring the test report of TR3 3990X, the real king of fever-grade products online.

CPU product specifications:

Ruilong Threadripper 3990X has a 64-core 128-thread specification, a 256MB L3 cache, a basic frequency of 2.9GHz, and a maximum acceleration of 4.3GHz, TDP 280W, which is matched with the motherboard of TRX40 chipset.

This specification has never been used in the civilian level. Even if the products of the server platform are included, Intel must use the top Xeon Platinum 9200 to get closer (glue 56 cores and 112 threads).

However, Intel let motherboard manufacturers make several game motherboards that support W-3175X (only 28 cores and 56 threads), and then it went away. It seems that they gave up.

Product packaging and accessories:

There is nothing special about the packaging of TR3 3990X. Here is a brief description of the packaging and accessories.

The accessories of CPU are also old four, such as special screwdriver, adapter water-cooled fastener, sticker and instruction manual.

TR3 3990X is still a CPU as big as a 2.5-inch SSD, and AMD seems satisfied with this architecture, which will last for a long time.

The back of the CPU is designed as a contact, so be careful of the small capacitor on the back. If you get hurt, you will be in big trouble.

Introduction of test motherboard:

Gigabyte’s motherboard was used in the last test, so let’s feel the ROG Zenith II Extreme Alpha this time, because we still have a ROG Zenith II Extreme, so we can tell the difference between Z2E and Z2EA by the way.

The number of accessories of the motherboard is quite rich. Includes 2-in-1 SATA 6Gb/s cable, 4-in-1 SATA 6Gb/s cable, 3-in-1 thermistor cable, 3-in-1 ROG woven SATA 6Gb/s cable, RGB light bar extension cable (80cm), ROG DIMM.2 fan rack package, 5xM.2 screw package, Q-Connector kit and ROG coaster. ROG large sticker, ASUS 2×2 dual-frequency Wi-Fi mobile antenna, 2-in-1 rubber pad, dual-function screwdriver, ROG thank you card, fan expansion card II, fan expansion card II power cord, fan expansion card II NODE connecting cable, fan expansion card II screw package, and public and driver ∪ Disk, user manual, fan expansion card II user manual.

The more interesting accessory is the ROG fan expansion card, which can expand the fan, temperature measuring point and RGB LED. However, there is a disadvantage that the power interface on the card is special, and the patch cord only supports the graphics card 6PIN, which may cause the power supply line of the graphics card to be tight for multi-card users.

The fan extension body provides 6 x 4-pin chassis fan socket, 3 x 4-pin RGB interface, 3 x 2-pin thermal sensing interface, and data lines to support the linkage control of the motherboard.

A nice detail is that the fan expansion card adopts the standard hole position of 2.5-inch SSD, which can be conveniently fixed in the chassis.

Nowadays, high-end motherboards generally take the armored route, and Z2EA is no exception, including motherboard backplane, CPU power supply and cooling, rear window IO, rear window baffle, audio system, M.2 slot, chipset cooling and VCC power supply and cooling. The motherboard uses three fans to provide active heat dissipation, two for CPU power supply and one for motherboard chipset.

The CPU base is TRX40 specification, which is the same as the previous generation TR4, but the CPU motherboards of the two cannot be mixed.

Since the TRX40 is packaged in LGA, the motherboard base will be covered with pins, so be careful.

The CPU power supply of the motherboard is 16-phase digital power supply, the PWM chip is ASP1405I of ASUS, and the input capacitors are seven nichicon FP10K solid-state capacitors with a capacity of 270 microfarads and a voltage of 16V；; MOS is one DrMOS for each item, the model is Infineon TDA21490, and 90A； can be provided in single phase; The power supply inductance is one enclosed inductance for each item; The output capacitance is 5 polymer capacitors with a capacity of 470 microfarads.

CPU VCC power supply uses 4 phases exaggeratedly, and the input capacitance is 4 polymer capacitors; MOS is one DrMOS for each item, and the model is Infineon TDA21462；; The power supply inductance is one closed inductor for each item.

There is an ICS9VRS4339BL between VCC power supply and CPU, which is a clock chip used to unlock the external frequency adjustment ability of CPU.

The motherboard has eight memory slots with four channels and supports DDR4 memory.

The memory is powered by two phases on each side, the PWM chip is ASP1405I of ASUS, and the input capacitor is a nichicon FP10K solid capacitor with a capacity of 270 microfarads and a voltage of 16V；. MOS is one DrMOS for each item, the model is Infineon TDA21490, and 90A； can be provided in single phase; The power supply inductance is one enclosed inductance for each item; The output capacitor is 31 nichicon FP10K solid-state capacitors with a capacity of 560 microfarads and a voltage of 6.3V.

The motherboard chipset is still TRX40, so there is no need to introduce it too much.

Next to the memory slot, there is a slot with metal foolproof, which is used to expand two additional M.2 SSD, taking the PCI-E channel.

By the edge of the motherboard memory slot, you can see the main power supply interfaces, which are 2*USB 3.1 TYPE-C, motherboard 24PIN power supply, 6+8+8 CPU power supply and CPU FAN+CPU OPT from the left. Asus has provided 6+8+8 22PIN power supply for CPU, which has exceeded the power supply scale of conventional high-end graphics cards.

Near the chipset side, from the left in the figure are the water-cooled flow rate monitoring interface, SYS FAN, 8*SATA 3.0, horizontal USB 3.0 and SYS FAN. Behind SYS FAN on the left is a liquid nitrogen mode switching jumper.

It can be seen that there is an ASM1074 chip on the left, which is used to provide channels for the two USB 3.0 interfaces on the board. There are two ASM1061 chips on the right, which can turn out two SATA 3.0 interfaces respectively.

Next, look at the bottom of the motherboard, next to the chipset. From the left in the figure, there are 2*USB 2.0, 1*USB3.0, NODE (data interface of fan expansion card), several adjustment switches (detailed in the figure below), restart key, on-off key, water cooling temperature interface and chassis panel control interface.

There are many adjustment switches on the motherboard. From the left in the inner row in the figure, there are M2_3 switch, SAFE BOOT button, RETRY button (forced restart self-test), BIOS switch button and fan switch at full speed. The two switches on the outside, the upper one is RSVD switch (for maintenance only) and SLOW MODE switch (for forced low frequency). These can facilitate the debugging of the motherboard to a certain extent, and can also be used for extreme overclocking.

In the diagram near the PCI-E slot of the main board, from the left, the front audio, PCI-E slot auxiliary 4PIN power supply, TPM, 3PIN RGB, 4PIN RGB and SYS FAN are provided respectively.

The graphics card slot of the motherboard is configured as NAX16NAX8X16NAX8. Mainly for dual graphics cards to optimize the swing, and can not support four cards.

There are two onboard M.2 SSD slots between the graphics card slots, and one on the back of the motherboard. This allows Z2EA to install up to 5 M.2 SSD.

PCI-E 4.0 requires very high signal stability, so a large number of PI3DBS16000ZHE chips can be seen on the motherboard for the relay amplification of PCI-e signals. At the same time, due to the high specification of Z2EA, the number of PCI-E channels of TRX40 is not enough, so a large number of P13EQX16 chips are needed for channel switching.

Next, take a look at the rear window of the motherboard. From the left, there are CLEAR CMOS, USB BIOS FLASHBACK, WIFI antenna, 2*USB 3.0+2*USB3.1, Gigabit network port +USB 3.1 A+C, 2*USB 3.0+2*USB3.1, and 10 Gigabit network port+USB 3.1A+USB 3.2 (2×2).

The audio part of the motherboard is the mainstream flagship motherboard audio solution. The main chip is S1220, which is actually a ROG customized version of ALC1220; Because the motherboard chipset does not support HD AUDIO, two ALC 4050H are used to connect the chipset. An additional ESS 9018 chip is also used for the DAC work of the rear window interface. There is also a power amplifier chip for front audio on the back of the motherboard. The whole scheme is not particularly exaggerated, but it still maintains the specifications that the flagship motherboard needs to show.

The network card of the motherboard is configured with Gigabit+10Gigabit, with the Gigabit network card being Intel’s I211AT and the 10Gigabit network card being AQUANTIA AQC107.

The motherboard wireless network card is also a relatively new AX200, which can support WIFI 6.

This time, ASUS introduced the new interface USB 3.2 2X2 in the rear window, so you can see the chip ASM3242 on the motherboard. The ASM1074 next to it provides four USB 3.0 interfaces for the rear window.

Z2EA uses dual BIOS, and the LED on the left in the figure shows which BIOS is being used, which can be switched when it is turned off. The BIOS chip on the right is a USB BIOS FLASHBACK function chip, and the model is AI1315.

Let’s take a brief look at other chips on the motherboard. ASUS’s motherboard TPU will naturally not be absent, and it can be used to help with one-button overclocking and other functions.

The SUPERIO chip of the motherboard is NCT6798D, which is a relatively conventional material.

The RGB control of the motherboard is handled by an AURA chip.

Finally, simply compare the differences between Z2E and Z2EA, in fact, the overall specifications are very close. Mainly due to some adjustments in power supply.

The following pictures are all Z2E, but MOS is different. Z2E is TDA21472, the number of phases on CPU power supply is the same as 16, and PWM is also ASP1405I. Therefore, the theoretical power supply capacity of each phase will be reduced from 90A to 70A.

VCC power supply is the same 4-phase TDA21462 scheme.

There are obvious differences in memory power supply. The Z2E is still an ASP1103+ upper and lower bridge, and the materials used in the scheme are obviously weaker.

So in general, Z2EA is mainly an enhanced version of Z2E, which promotes the power supply of CPU and memory to the strongest state of alternative schemes in the industry. So if people who already have Z2E don’t have to be too entangled, Z2E itself is already very strong.

Introduction of test platform:

Let’s take a look at the test platform.

Now that we have the Ripper, counting boxes has become a very ceremonial thing. This is also the first time that I have encountered that the CPU can’t display the display area diagram after displaying according to the logical thread, only the color block depth and percentage are left to reflect the CPU occupancy.

TR3 3990X is in the baking machine state. If the single baking CPU mode with less load is selected, the whole core frequency is 3.45GHz.While the CPU frequency is only 3GHz when the AVX2 instruction set is called, which corresponds to the result of power consumption test.

It can be maintained at around 4.15GHz under single-core test.

The memory is Kingston’s DDR4 8G*4. The actual operating frequency is 3200C14.

There will be a test with a unique display in the middle, and the graphics card is the water-cooled version of VEGA 64 by Dylan Hengjin.

SSD is three pieces of Intel 535. 240G is used as the system disk, and 480G*2 is mainly used to play test games.

The NVMe SSD test used Intel 750 400G.

The radiator is the SHADOW light shadow 360 of Josboro, and this water-cooling device has no TR4 fastener, so I used a third-party Intel to TR4 fastener.

Silicone grease is CTG-2 from Josberg.

The power supply is the extremely cool V1000.

The test platform is BC1 of Streacom.

Introduction of performance test items:

For children’s shoes interested in further understanding the comparative performance, detailed test data will be provided here. If you don’t want to see it, you can skip to the last summary. The test will be roughly divided into the following parts:-CPU performance test: including system bandwidth, CPU theoretical performance, CPU benchmark test software, CPU rendering test software, 3DMARK physical score-collocation independent display test: including independent display benchmark test software, independent display game test, independent display OpenGL benchmark-power consumption test: power consumption measurement under independent display platform.

Since this test, many test items have been added and some adjustments have been made, as follows:

CPU performance test: added CineBench R15 EXTREME (counting 1CPUXCPU results) and V-RAY NEXT BENCHMARK (counting CPU results).

　With the unique test: added BASEMARK, Neon Noir Benchmark and Extreme Peak. Due to the driver version, fistful of dollars 2 and War Machine 5 cannot join temporarily.

Only for the change of CPU thread performance statistics table (without affecting other comparisons): single thread, adding CineBench R15 EXTREME. Multi-threading, adding Time Spy EX CPU, CineBench R15 EXTREME and V-ray next benchmark; Remove X264 FHD, X265 FHD, winRAR multithreading, 3D MARK SKY CPU, 3D MARK SKY FIRE CPU and 3D MARK SKY Time Spy CPU.

Performance test and analysis of CPU;

According to the system bandwidth test, the memory bandwidth of TR3 3990X is higher than other series products, and slightly higher than the corresponding four-channel platform of Intel. There are actually 8 CPU DIE in TR3 3990X, so the counted cache bandwidth of L1L2L3 is very scary, which can basically be compared by multiples.

The theoretical performance test of CPU is carried out with the built-in tools of AIDA64. The theoretical performance of TR3 3990X is horrible, reaching 11.8 times that of i5-9400F, 7.2 times that of i9-9900K and 3.4 times that of R9 3950X.

CPU performance test mainly tests some commonly used CPU benchmark software, and also includes some application software and CPU test items in the game. This link will involve testing in different load environments, which is also the closest to the daily use environment. In this link, TR3 3990X can still surpass all other competitors, leading R9 3950X by 30%.

CPU rendering test, which tests the rendering ability of CPU. The test will count the test results of single thread and multi-thread, so this link will generally be the closest to the comprehensive performance comparison of CPU (single core and full core are basically half). On the whole, TR3 3990X is 2.2 times that of R9 3950X and 2.8 times that of i9-9900K.

The 3D physical performance test tests the physical scores in the 3DMARK test, which are mainly related to the CPU and have a small impact on the game performance. The performance of the four-channel platform in this link is generally not good. TR3 3990X will be lower than R9 3950X, but the same is true for Intel. The 14-core i9-10940X can’t beat the 8-core i9-9900K.

CPU performance test section comparison section:

According to the comprehensive statistics of CPU,The younger brother TR3 3960X can already seal the door, and TR3 3990X is used by AMD to brush the data.

The single thread and multi-thread of CPU are also decomposed here.

Single thread: Since the single-core frequency can reach 4.3GHz, the single-core performance of TR3 3990X is not very virtual, and it belongs to high-end CPU.

Multi-threading: Multi-threading performance TR3 3990X began to brush data casually, which is multiple of the following products.

With a stand-alone test:

The graphics card is VEGA 64, and AMD CPU will still have an advantage in running points. This project will be obviously stronger than i9-10940X.

According to the 3D game test, the game performance of TR3 3990X is relatively weak, but the weakness is not serious, which is roughly equivalent to the level of R7 2700X.

Decomposed into different generations, TR3 3990X performed slightly better under DX9, but slightly weaker under DX11 and DX12. But they are all within the acceptable range.

According to the test of different resolutions, the performance of TR3 3990X is relatively average.

OpenGL benchmark test alone, the OpenGL part is based on SPEC viewperf 12.1 and LuxMark. This test is a professional computing test for graphics cards, and the gap is more related to CPU delay and single-thread performance. Therefore, TR3 3990X will be slightly lower than i9-9900K.

With a separate test section:

Judging from the test results,TR3 3990X basically solves the problem of single display collocation, which can give consideration to high performance and both ends of the game.

Disk performance test:

The disk test part uses CrystalDiskMark 6, and the data file of 1G runs 9 times, which can basically eliminate the test error. The tested SSDs are 535 480G and 750 400G, both of which are hung from the disk. Simply explain the concept in this test, SATA interface and PCI-E channel can be drawn from CPU or chipset (see how CPU manufacturers design). In principle, we will test SATA and PCI-E from the chipset, but Z2EA only has PCI-E slots from the CPU, so we use the slots directly connected to the CPU.

In terms of disk performance, the performance of TR3 3990X is relatively general, and there is nothing outstanding.

Platform power consumption test:

The power consumption test is only carried out on the platform with a single display, and the overall power consumption of TR3 3990X is still relatively high. According to the test results, Z2EA has obvious power consumption limit in FPU test, and other test power consumption is relatively normal. In PM95, the power consumption of TR3 3990X can be 100W higher than that of TR3 3960X.

Detailed statistics:

Test summary:

The comparison groups in this test are i9-9900K, i9-10940X, R9 3950X and TR3 3960X. Compared with 100%, the benchmark is still i5-9400F, because the space relationship is not put in the table.

As far as the comprehensive performance of CPU is concerned, being the younger brother of TR3 series is enough to settle the following products, and TR3 3990X is just raising the bar further. Even with a large number of applications and single-threaded tests, the performance of TR3 3990X can reach 2.9 times that of i5-9400F, while that of Intel’s i9-10980XE is only about 70%.

With the unique part, TR3 3990X can also ensure that the game performance is in a good range (equivalent to 98.15% of i5-9400F). Because of the high score of running performance, the final score can be slightly higher than i5-9400F.

In terms of power consumption, the power consumption of TR3 series CPU is still relatively high.Due to the low standby and low load power consumption of TR3990X, the current of TR3990X is limited when the motherboard runs FPU test, so the power consumption of TR3990X is not particularly high in the final result. With reference to the test of PM95, the full-load power consumption of TR3 3990X can be about 100W higher than that of TR3 3960X.

Finally, the last CPU ladder diagram is for your reference. The performance part only compares the test items related to CPU, and does not include the results of the game performance test.

Since 2017, the system, driver and BIOS have great influence on CPU performance, so this table is only for directional reference.

Simple summary:

About CPU performance:

In terms of CPU performance, TR3 3990X is almost a data brush, which makes Invincible even more lonely.

About collocation alone:

In terms of game performance, TR3 3990X continues the performance of other two products in TR3 series, which ensures that the related software and games with unique display can run well.

About power consumption:

The power consumption of TR3 3990X is really high, but 360 water cooling can ensure the basic use is not a problem. Of course, it is more worthy of this CPU to customize a set of water cooling conditionally.

Generally speaking, TR3 3990X, like R9 3950X, is a product used by AMD to show muscles, in order to open an insurmountable gap with Intel. At present, the performance gap between Intel’s fever-grade products and TR3 3990X is many times, which completely loses its comparative value. 、

It can even be said that TR3 3990X doesn’t need to make a comparison, and TR3 3990X doesn’t care, because you are bugs.

Waste edible oil in Japan is recycled and used to make aviation fuel.

In a resource recycling station in Shibuya, Tokyo, there are separate recycling bins for different items, which are used to recycle small household appliances, fluorescent tubes and waste cooking oil. The recycling bins are filled with many oil bottles brought by nearby residents, some of which are used kitchen waste oil and some of which have passed the shelf life. After recycling, these waste oils can be used to produce feed, industrial oil and fuel, including aviation fuel.

Japan: Sustainable aviation fuel helps reduce carbon emissions.

This Friday, Narita Airport will introduce sustainable aviation fuel made by Japanese companies with waste edible oil as raw materials. Because the edible oil used in Japan mainly comes from plants, compared with traditional aviation fuel, the new fuel is expected to reduce carbon emissions by about 80%, and its impact on the environment will be greatly reduced. Japan has placed great expectations on the development of sustainable aviation fuel. It is estimated that Japan produces about 500,000 tons of waste cooking oil every year, including households and restaurants, of which 4/5 comes from catering and food processing industries and 1/5 comes from households. Relevant laws prohibit the excessive discharge of waste oil into sewers, and the overall recovery rate is about 80%. Therefore, in Japan, where energy is scarce, these waste oils are also called "urban oil fields".

In 2030, the utilization rate of renewable fuels in Japan’s aviation industry may reach 10%

The Japanese government plans to replace 10% of domestic airline fuel with sustainable aviation fuel by 2030. In order to promote popularization, in the first half of this year, related enterprises in Japan’s energy and aviation fields have established consultation mechanisms and started cooperation in this regard.

New fuel fever drives the price of waste edible oil in Japan higher.

With the high price of traditional energy, including Japan, the development of new energy in the world is accelerating. The increasing attention to sustainable aviation fuel has also driven the price of waste edible oil in Japan to rise. According to Japanese media reports, the purchase price of waste oil has increased significantly recently, and in some areas it has doubled compared with last year. Even in some catering streets, there has been a phenomenon of stealing waste cooking oil at night. With the expansion of the sustainable aviation fuel market, the price of waste edible oil in Japan is expected to continue to rise.
