e-core and p-core aware in Windows 10 OS

[chrcoluk]

Doing my testing on Windows 10, cinebench first ran on e-cores with all p-cores automatically parked.

But in power settings explorer. one of the many hidden settings in windows, this got my interest.

I set it to performant cores, and cinebench then picked out a p-core. (prefer also works and it picks out a 5.4ghz core).

Interesting also that the e-core was only barely 10% slower than my 9900k single core.

E cores are basically as fast as Skylake cores so that's in line. People give them a lot of crap, but it's the equivalent of two 9700K CPUs worth of secondary cores for the cost of a small amount of die space.

The laptop that I'm testing for a few weeks has 16 of those e-cores. Just a 4years ago, I was using a laptop with a quad core 7700hq.

Yeah they much faster than what was originally made out to be.

No they were always made out to be useful by Intel. It's the community that are still wrapping their heads around having two different cores, one of which is "slower", and therefore useless, apparently. Having four more e cores is more useful than one P core though, especially when you take into consideration you get at least six P cores.

I meant the community.
