Doesn't c stand for e-cores? Packing up to 32 e-cores must be easier than with normal cores.
Also kinda wish they went the other direction a little, cut cure counts and put more cache across all levels on some cores instead for better single thread performance, a 'very big' core so to say. Intel's cache sizes have been larger then amd since alder lake and there stayed competitive despite their process node disadvantage
Not quite an e-core but the goal is the same: Make more efficient use of the available die space by packing in more, slower cores.
The difference is that Intel's e-cores achieve this by having a different architecture and support less features than their p-cores. E-cores for example do not support multi threading. E-cores are about 1/4 the size of a o-core.
AMD's 4c cores support the same features and have the same IPC as full zen 4 cores but operate at a lower clock speed. This reduces thermal output of the core, allowing them to pack in the circuitry much more densely.
Undoubtedly Intel's e-cores take advantage of this effect as well and they are in fact quite a bit smaller than 4c: a 4c core is about 1/2 the size of a zen 4 core. The advantage of AMD's approach is that having the cores be the same simplifies the software side of things.
