Hello,
AMD's Zen 4 EPYC could get HBM upgrade to fight Intel Sapphire Rapids

And read my following writing about Intel Next-Gen Sapphire Rapids Xeon with High Bandwidth Memory:
Intel to Launch Next-Gen Sapphire Rapids Xeon with High Bandwidth Memory
"Current eight-channel DDR4-3200 memory designs, for example, have a theoretical maximum of 204.8 gigabytes per second, which pales in comparison to GPUs which quote 1000 gigabytes per second or more. GPUs are able to achieve higher bandwidths because they use GDDR.
At the very least, we expect the equivalent of up to 8-Hi stacks of HBM2e, up to 16GB each, with 1-4 stacks onboard leading to 64 GB of HBM. At a theoretical top speed of 460 GB/s per stack, this would mean 1840 GB/s of bandwidth, although we can imagine something more akin to 1 TB/s for yield and power which would still give a sizeable uplift."
