"35% Smaller than Zen 4, but with Identical IPC"

It is very impressive to keep all of Zen 4's functionality and only sacrifice frequency and L3 for almost double the core density. I hope They will release some consumer products with this in the future like a 7970x with 8 Zen4 and 16 Zen4c cores.

With the official announcement it confirmed the previous leaks, for a more detailed breakdown see: https://www.semianalysis.com/p/zen-4c-amds-response-to-hyperscale

Did I read that right...128 cores / 256 threads. That's bonkers. I guess those are only useful in extremely parallel workloads, or you'll be hitting https://en.wikipedia.org/wiki/Amdahl%27s_law limitations? I'm not a CS grad, so take this with a pinch of salt.

This is also a way to get around software that's licensed per socket instead of per core. Allows companies to condense the number of machines and licenses.
