"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

Yeah, at that thread count only a few workstation applications (maybe video encoding and code compilation) scale well.

The c in 4c is supposedly referring to cloud where it's possible to run 128 tiny independent VMs on a chip like that. Being independent means those should scale linearly aside from the shared memory and IO bandwidth.

Those numbers are just so wild. Very impressive :)
