Frontier will cover the size of over 2 basketball courts and will have more performance than the top 160 current fastest supercomputers combined.

The exact specs for Frontier haven't been released yet, but it will be built using AMD EPYC CPUs, Radeon Instinct GPUs, and Cray Slingshot interconnects. Each node in the system will have one CPU and four GPUs. The supercomputer will be used for many applications in scientific fields including sub-atomic structures, weather, genomics, fusion, and more.

interesting stuff, EPYC Rome most likely, 7nm based?

Yeah saw that, potentially zen3 or even zen4 CPUs in there :pimp:
AMD didn't reveal which specific generation of its GPUs and CPUs will power the system, although CEO Lisa Su did announce that both components are customized for the deployment.

AMD's EPYC processor has been optimized with support for new instructions that provide optimal performance in AI and supercomputing workloads, with Su saying, "it is a future version of our Zen architecture. So think of it as beyond..what we put into Rome."

That could indicate that AMD will use a custom variant of its next-next-gen EPYC Milan processors for the task, but that remains unconfirmed. Those processors have already been tapped for the DOE's Perlmutter supercomputer that is also built with Cray's Shasta building blocks. We have extensive coverage of that design here.

AMD is making big buck with EPYC in the coming years, I wish I had bought stock in 2016 when it was only $2 a share, LOL
