Always keen for more cores, but even new games seem to struggle to scale linearly with cores, most seem to support 4-6 cores if you're lucky, with extra cores being somewhat lackluster.
@AnonymousLlama Especially E-cores, for games they are nearly useless, only good for offloading other tasks and maybe for decompression in few titles. But for productivity, that's a nice boost.
On any Windows but 11, they can even be detrimental as there's no P-Core priority for games.
The only thing that fixed my constant stuttering in Metro Exodus was disabling the E-Cores in the BIOS, smoother games ever since.
