Intel Raptor Lake: Too many low performance E-cores

[AZE]

E core is not slow.
It is decently fast, as fast as skylake.
For a single P core, one can get 4 E core.

During power limited work load, where a single P core will be forced to down clock, 4 E core will be much faster.
During light workload, E core would free up P core for performant applications. The apps and OS need to support that though.

The idea was not even new, that was how power limited mobile devices had been doing for years, Big.Small configs.

skylake is actually already quite slow by todays standards, dont forget the e cores dont clock as high (max 3.9ghz on 12900k) or have hyperthreading too.
