NVIDIA DGX-A100 Systems Feature AMD EPYC "Rome" Processors

NVIDIA is leveraging the 128-lane PCI-Express gen 4.0 root complex of AMD 2nd generation EPYC "Rome" enterprise processors in building its DGX-A100 super scalar compute systems that leverage the new A100 "Ampere" compute processors. Each DGX-A100 block is endowed with two AMD EPYC 7742 64-core/128-thread processors in a 2P setup totaling 128-cores/256-threads, clocked up to 3.40 GHz boost.

This 2P EPYC "Rome" processor setup is configured to feed PCIe gen 4.0 connectivity to eight NVIDIA A100 GPUs, and 8-port Mellanox ConnectX 200 Gbps InfiniBand NIC. Six NVSwitches provide NVLink connectivity complementing PCI-Express gen 4.0 from the AMD sIODs. The storage and memory subsystem is equally jaw-dropping: 1 TB of hexadeca-channel (16-channel) DDR4 memory, two 1.92 TB NVMe gen 4.0 SSDs, and 15 TB of U.2 NVMe drives (4x 3.84 TB units). The GPU memory of the eight A100 units add up to 320 GB (that's 8x 40 GB, 6144-bit HBM2E). When you power it up, you're greeted with the Ubuntu Linux splash screen. All this can be yours for USD $199,000.

FluffmeisterEpyc is a silly name to be fair.
Huh, AMD has a history of similar names - Phenom, Bulldozer, FX, Opteron... Athlon, Sempron...

Intel's Xeon is very weird, too.

RH92They give back some of what they are about to take in the GPU market , it's called philanthropy :roll::roll::roll:
You do know that the T.A.M. on the x86 market is larger, by many, many magnitudes, that the dGPU T.A.M., right?

Ashtr1xIs there any rumor or news piece that tell us next year Xeon having PCIe gen 4 ? RKL is having that but what about the Xeon ?
The newly announced W-1200 range is still PCI-e 3

Wait a minute, no one asked "But can it run crysis™?"

For me, asking that question, even if just for the chuckles, became pointless after Linus from LinusTechTips ran Crysis to the point of being somewhat playable using only an Epyc processor through software rendering.

EDIT: Also, this is just PR, but I still get a laugh out of this:

Lisa Su isn't stupid, business is business.

If you think it's funny, then Lisa Su thinks your stupid too.

Giant air filter.
ChomiqThat front looks like a HEPA filter.
Most likely is.

Yes, we almost made it to the new world order and you done screwed up it all up, son.

Vya DomusTo be fair one of the reason for going with AMD is probably that they want to give absolutely nothing to Intel in terms of market share. Remember, their biggest competitor right now is Intel, up until now they had no choice but to deal with them. No more I guess.
I think this is a valid reason, and with another giant also trying to squeeze its way into Nvidia's territory, it is perhaps wiser to give business to the smaller one (AMD). I feel cost vs performance could be the otjer moltivation for the move.
