NVIDIA Ditches Intel Xeon, Goes All Onboard With AMD’s EPYC CPUs With Next-Gen Ampere GPUs


In a surprise unveil, NVIDIA has decided to ditch Intel's Xeon CPUs and go all onboard with AMD's EPYC Rome processors to power its next-generation Ampere GPU powered DGX systems. This will be the first full outing of two next-generation 7nm server products in the same platform featuring insane hardware specifications.

The news announcement comes on the launch of NVIDIA's Ampere GPU which is by far the biggest 7nm GPU ever built. In the presser, NVIDIA revealed full technical specifications of its latest DGX-A100 system that will be utilizing NVIDIA's 7nm Ampere GPUs and AMD's 7nm EPYC Rome CPUs, marking the first time that green team has opted for AMD's server chips for use in its flagship HPC platform.

The DGX A100 system will be housing 8 NVIDIA Tesla A100 Tensor Core GPUs which we have fully detailed in a separate post here. The platform will feature a total of 320 GB worth of GPU capacity, that's 40 GB per GPU, and peak performance rated at 5 petaFLOPs (AI) & 10 petaOPs (INT8). There are in total 6 NVSwitches onboard the system, all featured under massive tower heatsinks but let's talk about the CPU side.

On the CPU side, we are looking at two AMD EPYC 7742 'Rome' CPUs which are based on the TSMC 7nm process node. The CPUs feature 64 cores and 128 threads each, making for 128 cores & 256 threads in total. The CPUs are clocked at a base frequency of 2.25 GHz and a boost frequency of 3.4 GHz. The system itself features 1 TB of DDR4 memory, up to 15 TB U.2 and 2x 1.92 TB NVMe SSDs, 8 single-port Mellanox connections rated at 200Gb/s HDR (Infiniband) and a single dual-port switch from Mellanox. The NVIDIA DGX-A100 system is shipping now for a starting price of $199,000 US.

This is definitely a huge blow for Intel's Xeon CPUs and shows how much AMD EPYC CPUs have clawed their way in the hearts and minds of the HPC market. Expect more information on the NVIDIA DGX-A100 Ampere GPU powered systems to be posted here soon!
