Amd got a new overbalance order today,Building El Capitan supercomputing for DOE with Cray of HPE, with a budget of $600 million, AMD's next generation CPU and radeon acceleration card will be used, which will come out in 2023, with floating-point performance of 20 billion times.What are the specifications of El 13 Capital? Now there are more than 3 years to go, so the details of CPU / GPU are unknown. It can be determined that the third generation of infinity fabric bus is used. Each epyc CPU is equipped with 4 radeon insight accelerators.

For Supercomputing CPUs, it's now more reliable to say that the new generation epyc of zen4 architecture will be a new upgrade, and the platform will also be upgraded to ddr5 and PCIe 5.0. These advanced technologies correspond to the era of 10 billion supercomputing times, and can meet the requirements in performance and efficiency.

In the epyc server, the product corresponding to zen4 architecture is Genoa Genoa, Italian city, while the current epyc code is Rome, and there will be Milan Milan with zen3 architecture between them. Its basic specification is very similar to the current Rome II Xiaolong, which is also DDR4 memory and PCIe 4.0 bus and SP3 package interface, keep the platform compatible, it seems that they will focus on architecture optimization and performance improvement.

Now the biggest mystery is the architecture and process of Zen4 and Genoa processors, whether to stick to a maximum of 64 maximum of 64 cores or upgrade to 128 cores, whether to use five nm or the latest revelations continue to use seven nm of grinding, these two improvements affect the heart of A rice and the industry.

It is believed that everyone expects AMD to build 128 core 256 thread processor with 5nm technology, and continue to excel in high-performance computing.

Finally, it will be revealed soon, said Forrest norrod, general manager of AMD data center and embedded businessAMD will announce the zen4 / Genoa processor at the upcoming analyst meeting, that is, this Thursday - it will be early tomorrow morning in China.
