[PConline Information] there have been all kinds of rumors that AMD is about to release a new 7nm graphics card and CPU, and today it has finally confirmed the release of the product model. In San Francisco, on the morning of November 7, US time, AMD held a large-scale press conference, which mainly introduced server-grade AMD EPYC processors based on 7nm technology and Radeon Instict accelerator cards of 7nm based on Vega architecture.

The theme of this conference is NEXT HORIZON.

Lisa Su first reviews the achievements of AMD in the professional field in the past year, which is significantly higher than that before EPYC's listing, and has deep cooperation with many technology giants, such as Microsoft, HPE, Oracle, Cray, Chao, Tencent, Baidu, gearbest and so on.

Today, AMD officially announced that EPYC Xiaolong server has officially launched Amazon AWS, 's first three products, Amazon Elastic Compute Cloud (EC2) cloud instances have been launched immediately, which is also the most popular AWS cloud instance series.

Then there is the highlight of the press conference, the CPU&GPU of 7nm, which we will analyze one by one.

First of all, the most eye-catching is the second generation of EPYC Xiaolong, the world's first 7nm server processor.

EPYC code "ROME", that is,The "Rome" that "Rome was not built in a day"Oh, that's a good meaning. Based on the new Zen2 architecture, it has 64 scary cores and 128 threads, which has doubled compared with the previous generation. At the same time, the performance and physical bandwidth of IPC and IWeiO have also improved.

From the point of view of the exposed core on the spot, the second generation EPYC has adopted a brand-new architectural design, not a generation of minor fixes. Each processor has eight CPU Die, manufactured by 7nm process, with a total of 64 physical cores integrated in each Die. At the same time, in order to better coordinate the cooperation of so many CPU cores, an I Die, O Die, is specially designed to be placed in the central position, which is responsible for input and output control. The process is 14nm.

According to official data,Rome EPYC has doubled its performance compared to the first generation, and its floating-point performance has quadrupled, which is a major upgrade that has never been seen before.

  The scene also uses a single-way ROME EPYC to compare the two-way Intel with the strongest platinum Xeon Xeon Platinum 8180M, and ROME can easily win even in the case of 1V2.

In addition, ROME EPYC is the first processor to support PCI-E 4.0 technology, which means that the processor bandwidth channel is doubled, greatly improving performance with accelerators.

Finally, AMD said the explosive processor will be officially shipped in 2019.

Considering that the first generation of AMD Ryzen is castrated from the first generation of EPYC, and the final number of cores is 1max 4 of the first generation of EPYC, the number of cores of EPYC has doubled this time.This may mean that the maximum number of cores in next year's third-generation AMD Ryzen is likely to reach 16 cores and 32 threads.It's a little excited to buy a 16-core CPU,1500 for 3000 yuan and an 8-core CPU, for the thought of it.

AMD also officially announced the world's first GPU-- made by 7nm technology today.Radeon Instinct MI60 、 Radeon Instinct MI50 .

The 7nm Vega core integrates 13.2 billion transistors, an increase of 6.4% from the current 14nm Vega 12.5 billion, while the core area is 331sq mm, which is 31.6% smaller than the current 484smm, and the transistor density has doubled.At the same power consumption, the performance of the new core is improved by more than 25%, while the power consumption of the new core is reduced by 50% at the same frequency.

With the HBM2 memory of 32GB, the bandwidth of video memory can reach a scary 1TB, with built-in ECC error correction.

At the same time, this video card is also the first graphics card in the world to support PCI-E 4.0,The two-way bandwidth is 64GB, and with the help of the Infinity Fabric system bus with bandwidth up to 100GB/s, it supports four-way GPU parallelism, and has excellent scalability. The performance of the two-way is improved by 99%, the four-way is 298% higher than the single-way, and the eight-way is 664% higher than the single-way.

In terms of theoretical performance,MI60 FP64 double precision floating point maximum 7.4 T flopsline FP32 single precision maximum 14.7 T Flopsline int integer maximum 118 TopsMagne.

  The professional performance of MI25 is up to 8.8 times higher than that of the same 14nm Vega core.

At the same time, it surpasses or is basically the same as NVIDIA's most powerful Tesla V100.

AMD also announced the open source computing platform ROCm 2.0, and promised to open source completely.

According to AMD, the 7nm Vega core architecture has the world's fastest FP64/FP32 PCI-E floating-point performance, machine learning training and reasoning, world-leading video memory and scalability, and is the only hardware virtualization and end-to-end ECC error correction protection graphics card in the world.

The press conference of AMD is full of news, especially the EPYC performance of 7nm is very amazing, which makes us have more expectations for the third generation of AMD Ryzen next year. If we can use 1500 pieces of 8-core 16-thread CPU, with frequency above 4.5GHz next year, it will be really enjoyable.

With regard to 7nm's GPU, the overall performance related to artificial intelligence and professional performance has been greatly improved, and the power consumption has decreased significantly, but the single-precision improvement is general. Moreover, it was previously rumored that 7nm's VEGA architecture may not enter the game market, and now its improvement is mainly aimed at data centers, so we still look forward to a more practical NAVI architecture.
