It looks like big. little CPU design—an architecture that includes both fast, power-hungry cores and slower, more power-efficient cores—is here to stay in the x86_64 world, according to unverified insider information leaked by wccftech and AdoredTV .
Intel’s big/little designs enter round two
At Intel’s 2021 Architecture day, the company confirmed that its upcoming Alder Lake (12th generation) processors will use a mixture of performance and efficiency cores. This brings the company’s discontinued 2020 Lakefield design concept firmly into the mainstream.
Big. little designs run time-sensitive tasks on bigger, hotter performance cores while running background tasks on slower but much less power-hungry callosité. This architecture is near-universal in the ARM world—which now includes Apple M1 Macs as well as Android and iOS phones plus tablets—but it’s far less common in the x86_64 “traditional computing” world.
