“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
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.
Licensing per socket is something I’ve never heard of. Interesting idea. I suppose back in the day one socket = one processor, so they’ve not moved on from that model, eh?
