TIL that Intel CPUs have different types cores on the same chip (P-core and E-core) and the idea was previously implemented on ARM (big.LITTLE). Who thought this was a good idea and why?
@pro On phones, it's useful for power saving, less so on desktop chips. Having Zen4 and Zen4C cores on the other hand, they're the same architecture, the only difference is that the 4C have less cache and don't boost as high in clock speeds. Since usually only a couple of your cores are running full boost, that's usually a good tradeoff for getting more cores. It only saves them maybe 35% or so of space, rather than fitting 4 of them in the same space though.
