Optimizing the per-core performance configurations to favor certain cores at the cost of reducing the performance capacity for other CPU cores.
Maybe I'm talking non-sense and it doesn't matter. I remember back in 2017 with Ryzen being a new thing and the affordable high core count with ThreadRipper(EPYC was sold out or priced much higher at the time due to demand), but they couldn't hit the same frequency Intel chips were offering which was really useful for single threaded workloads. Company I was at had a software that had several processing stages where some where single threaded restrained for a long time, I thought a desktop equivalent of the ARM big.little cores would be neat, but others said that's what desktop CPUs cater to with their turbo/boost frequencies, having "big" or "little" cores wouldn't achieve anything?
That does seem to make sense now with turbo/boost frequencies scaling based on how much load the CPU is under, so that a single core/thread can go over 5Ghz.
