NVIDIA has gone down an alternate route with the introduction of its DGX A100 AI accelerator when put into comparison with previous variants of DGX systems. With the DGX A100, NVIDIA has opted to utilize AMD's EPYC line of CPUs, a change from previous models using Intel's Xeon Platinum.

Last month, we received news that NVIDIA was gearing up to launch the long-anticipated and much-rumored Ampere GPU microarchitecture which has now taken form as the GA100. In the DGX A100's case, the A100 GPUs will use the cut-down variant of the GA100.
