Shulou(Shulou.com)11/24 Report--

CTOnews.com, December 10, at the Tencent Global Digital Ecology Conference in 2022, Tencent Cloud and AMD jointly launched Xinghai self-research server AC222 and cloud instance SA4 with the fourth generation AMD EPYC processor. The overall performance of this generation of servers is up to 95% higher than that of the previous generation, and the core density is up to 50% higher than that of the previous generation. On the basis of ensuring stability and reliability, double breakthroughs in performance and energy efficiency are achieved.

The following are the features of Tencent Cloud's next-generation Xinghai server:

Computing performance: based on "Zen 4" core architecture, based on new logic design and advanced process technology (5nm), core performance is greatly enhanced

Memory performance: supports the new DDR5 12-channel memory design with 2.45 times the memory bandwidth of the previous Xinghai system.

Deep learning: the newly added AVX-512 advanced vector extension, VNNI instruction set and BFloat16 data format effectively achieve a balance between computational efficiency and accuracy, and greatly improve training load accuracy and throughput.

Network function: based on 100G intelligent network card network architecture, through Yinshan self-developed DPU to provide up to 100Gbps network bandwidth, 50 million PPS, network delay as low as 5us; flexible RDMA network card supporting plug and play

Storage upgrade: continuous breakthroughs in storage performance, up to 1 million IOPS, and storage latency as low as 40us

System heat dissipation: in terms of heat dissipation, the cooling capacity of air cooling is increased by 42.8%, and it is compatible with cold plate liquid cooling design, which can effectively reduce carbon emissions.

I / O bandwidth: support the new PCIe Gen5 standard, double the data transfer rate, and more efficiently achieve intensive computing and data transmission among CPU, GPU, storage devices and various accelerated processors.

CTOnews.com learned that the fourth-generation AMD EPYC processor has up to 96 cores per CPU, supports high-performance DDR5 DIMMs and PCIe 5.0I / O, and has a complete software and hardware ecosystem of support, covering a wide variety of workloads, including database, virtualization, AI / ML, HPC, and so on.
