Only 122 Volta GPUs for that many CPUs(4,536)? Seems not like a lot.
Assuming a single socket and 64 cores, that's only 2% of motherboards having a GPU. It just means it has the potential for way more performance.

That's a funny thought, although I'd be surprised if there's any GPUs plugged into motherboards directly. They'll probably be in separate GPU racks connected via PCIe over network. With CPU and memory being racked as densely as possible.

Not that I really know anything practical about super computers lol.
