U.S.Authorities Restrict Shipments of Advanced AMD and NVIDIA Computing Accelerators to China and Russia

The last day of the calendar summer brought unpleasant news to Chinese and Russian AMD and NVIDIA customers.
The U.S.
government just banned both companies from shipping GPU computing gas pedals to those countries that meet certain performance criteria.
In the case of NVIDIA refers to products series A100 and H100, while AMD attributed to the list of \"sanctioned\" Accelerators Instinct MI250.Image source: AMDAccording to AMD representatives, as explained by Reuters, the supply of Accelerators Instinct MI100 did not fall under the ban.
At the same time, AMD believes that the new restrictions will not have a significant impact on the company's business, as trade turnover in this area were not large enough.
NVIDIA shares on the background of this news lost more than 6% in price, in the case of AMD reduction did not exceed 3.8%.
It is believed that the level of performance that determines the need for a ban on the supply of gas pedal in China and Russia, took the speed solution NVIDIA A100 with Ampere architecture.On the idea of American officials, advanced components of American origin should not be used by Chinese and Russian customers to improve military technology.
AMD and NVIDIA computing gas pedals, which are under the ban, can theoretically be used in speech recognition systems for eavesdropping and recognition of military objects in the images of terrain received from reconnaissance satellites.

AMD Instinct MI300 will be the world's largest APU with integrated Zen 4 processor

AMD first introduced the Instinct MI100 computing GPU based on CDNA architecture in 2020 as a competitor to Nvidia A100 to accelerate high performance computing (HPC) workloads.
Later, the CDNA 2-based Instinct MI200 and MI250X also appeared.
Now some information has emerged about the upcoming Instinct MI300 based on the CDNA 3 architecture.Advertisement The information comes from AdoredTV, which has obtained an internal slide detailing the Instinct MI300.
According to the leaked slide, the Instinct MI300 will actually be an APU with a Zen 4 architecture processor working together with a GPU and shared HBM memory.
 Insider @Komachi_Ensaka first tweeted about a big APU for the MI200 in December 2019, followed by a September 2021 tweet from @ExecuFix pointing to a new socket called SF5 supporting the MI300.
However, AMD has been considering the concept of a megaexascale APU with 32 CPU cores, a GPU and DRAM memory since 2015 and even published an article titled \"Design and Analysis of an APU for Exascale Computing\" in 2017. The recently leaked slide correlates well with the above information.
Zen 4 and CDNA 3-based APUs are expected to be completed by the end of May, with the first working sample in labs expected by the third quarter.
This would make it the largest exascale x86 APU for high-performance computing and data centers. While this information is likely true, it is unclear whether AMD will build all CDNA 3 gas pedals as APUs or produce GPUs and APUs separately.

AMD introduced the Instinct MI210 Computing Accelerator - CDNA 2 architecture and 64 GB HBM2E

AMD has unveiled the Instinct MI210 gas pedal designed for high-performance computing applications. The new product features a single GPU, which is primarily different from the flagship Instinct MI250 and MI250X introduced earlier.

The Instinct MI210 is based on a graphics processor with CDNA 2 architecture, which, unlike the gaming RDNA 2 in Radeon graphics cards, is aimed specifically at computing. Used chip with 104 processing units, which have 6656 stream processors. On a single chip substrate is located 64 GB of HBM2E memory with a 4096-bit interface and support for ECC. The memory bandwidth is equal to 1.6 Tbytes per second. The gas pedal is made as an expansion card with PCIe 4.0 interface. New product is equipped with Infinity Fabric interface for bundling two or four cards in one system. The Instinct MI210 only has one 8-pin connector for extra power so it can only draw 225W. At the same time, the TDP level is 300 watts. The novelty is equipped with a passive radiator, the air through which has to be driven by server fans. As for performance, AMD claims very high performance for the Instinct MI210. In vector FP 32 and FP64 operations, performance reaches 22.6 Tflops, and in matrix FP32 and FP64 & ; 45.3 Tflops. FP16 and bfloat16 operations have a performance level of 181 Tflops, and INT8 & ; 181 Tops. AMD also points out that the MI210 significantly outperforms its direct competitor, the NVIDIA A100 40GB, in high performance computing. AMD said that Instinct MI210 gas pedals will appear in systems from ASUS, Colfax, Dell, Exxact, Gigabyte, HPE, KOI, Lenovo, Nor-Tech Supermicro and Penguin in the coming months.
