But Turin classic is on N4.

So hopefully this Zen 5 Epyc will have not only better luck with their 128 core version to start, but with 3nm perhaps we will see a new “Large” model with 256 cores and 16 CCX’s.

This is incorrect. The Zen 5 based cores are on 4nm, only the Zen 5c based cores are on 3nm. And the IO die is the same for both and stil on 6nm.

These EPYC Zen Torinos do put a new stake in the ground in terms of bang-for-the-buck price/performance value proposition. If relative pricing had stayed at the Rome-Milan-Genoa level (say $250 / Rel Perf), then the story wouldn’t be as compelling, with a 3.5X price/performance improvement to Intel’s 2.6X — but Turin really pushes that envelope to a ground breaking 6.25X, for what is now a most impressive 15-year run (a much moved needle!).

It’s impressive also how they increased base clock from Milan to Genoa (say 2.4 GHz to 3.1 GHz in 64C) and then increased boost clock from Genoa to Turin (eg. 3.7 GHz to 5.0 GHz). Frontier’s CPUs are of the Milan 7713 64C 3rd gen running at 2.0 GHz, and I can only imagine how much improved it could be with Turins instead, and matching GPUs (faster, more power-efficient, less expensive).

Next up should be MRDIMM, PCIe 6.0, and CXL 3.0!

No, that’s where I started! But I went for the rhymes instead.
