Interesting, first with Intel, now with AMD. It's a good thing the US government is doing its part to make sure some competition remains, at least.

Aye, but can you/it play Crisis 3 in 4k......?? π)

No CUDA support. I'll pass.

So you're saying you're a low-key billionaire looking forward to buying one of these but will now pass due to no CUDA support?

Look how tables turned, 2 most powerfull supercomputers are based on AMD(CPU/GPU) and Intel(CPU/GPU), don't you wonder why no Nvidia's GPU's?, IMO he gonna sell his leather jacket soon.

Nvidia's CEO after seeing that non of the Two most powerful Supercomputers in the world will use their GPU's π.

As much as I'm happy for AMD's success and repeatedly remind people that AMD's GPUs are actually very good for compute workloads, it seems people here are getting a little bit carried away with their success in this situation. Supercomputers are a game of leapfrog. There's always one country, university, or corporation that releases the next best thing, using some company's latest-gen hardware, and then a few months later someone else does the same thing on a competing platform.
Trust me, soon enough there will be a server with Nvidia hardware ranking #1. And rest assured, they won't retain that position.

Ah but a short decade ago...[URL='https://www.nvidia.com/object/pr_oakridge_093009.html']the good ole' days

Mind you...nVidia's Fermi supercomputer at ORNL already had AMD CPU's in it...:)

You didn't get my point, for long time Nvidia's GPU's were the obvious choice for those Supercomputers and you see that AMD and Intel's started to get their place, on Self-driving vehicles sector all saw that there is an option to develop better Asics for their own needs with "little" money and 2~3 years, so it seems that NV gonna have harder life for near future.

the cray supercomputer is built for a specific type of task that amd gpu's are better suited for.
its only the most powerful in terms of that task.

Very interesting built , nice to see AMD chosen for such " Epyc " ( pun intended ) supercomputer π

After Watching this about Milan and the possibility that it will include 15 Chiplets and maybe SMT4, I think [my Imagination] I Have an Idea where AMD is going with it's future(Maybe Custom design?) HPC EPYC design on 7nm+:
1)Each CPU chiplet will be 6C/24T to save space/power while giving similar or better then 8c/16t performance.
2)Adding 4 custom Instinct GPU chiplets.
3)Adding 2 custom AI accelerator [Asics] chiplets.
4)1 I/O chiplet with HBM memory stack.
So the final EPYC Milan(?) can be HPC beast with:
48C/192T Zen CPU cores.
4 custom Instinct GPUs.
2 AI accelerator Asics.
1 I/O Chiplet with HBM 3D staking .

EDIT: I see that there was already great article on such HPC APU design:
https://www.overclock.net/forum/225-...lops-200w.html
So after reading some of it I changed my illustration:

And 8 Milans could be installed in Crayβs Shasta 1U with Direct Liquid Cooling:

Do you think that such chiplet design could be beneficial for HPC clients?
