‘race to idle’ doesn’t seem to be the preferred approach anymore. Instead we’re seeing CPU designers go down the path of multiple different sized cores, with different speeds and power consumption. So in this world more “efficient” task can be run on slower lower powered cores. Stuff that needs to happen as quick as possible is don’t on faster, higher powered cores. When you can, you just turn off the bigger cores completely. I don’t have benchmarks, but there must be some good power savings in it if ARM have built their BIG.little architecture around it, and Apple followed suit with their processors.
