AMD's smaller Zen 4c cores are functionally identical to full fat Zen 4 with the exception of offering half the L3 cache. And yet they somehow only take up half the space of a Zen 4 core.

AMD did it right.
This is amazing for laptops

I still think amd-pstate is lagging a bit when it comes to supporting their current product lineup.
Imo full support (including turbo-boosting, preferred core support etc etc) should be present before a new cpu generation launches, not a year later.

I really hope this patchset and the v9 turbo boost set will be merged for 6.10.

With all these hertero core setups, pretty soon the linux scheduler is going to have to start benchmarking them during boot to make effective scheduling decisions.
