I wonder if the P/E core thing is here to stay. Sure, we had it for a while now on phones, but I'd say they are still a different target when it comes to the desire for power saving.
Overall they cause additional complexity for the chip itself, the OS scheduler, and software developers. See the whole AVX512 debacle. It seems like a quick solution, but once the performance race slows down again it might just make more sense to focus on making the fast cores more power efficient when under light load.
- ColonelPhantom 4y agoPower efficiency isn't actually the point on desktop. The point is that a Gracemont cluster is around the same size as a Golden Cove core, while being faster in multithreaded workloads. However, because they're slow at lightly threaded work you still need some really fast cores too. Because Gracemont is so small, a chip can pack more MT performance for the same price.
