> seems like Intel wouldn't do this

Wouldn’t do what? Intel has more E-cores than P-cores on most of their range, and especially on the higher end e.g. on raptor lake S the i9 all have 16 E and 8 P, the i7s have 8:8, only the lower end of the i5 (below 13500) have more P than E cores. And the i3 have no E cores.

The story is somewhat similar on mobile (H and HX), a minority of SKUs have more P than E, and none of them in P and U.

In fact that was one of the things which surprised me when Intel started releasing asymmetric SMT, they seemed to bank heavily on E cores when mobile and Apple had mostly been 1:1 or biased towards P cores.

I think you confirmed what you were replying to. Intel makes the numbers get bigger as you go up, regardless of whether that makes the most sense.
Oh yeah I misread the comment.

Although that’s not quite true either e.g. on raptor lake H, the upper i5 (13600H) has 8 E cores while the low range i7 (13620H) has 4, but the i7 has 6 P-cores versus 4. The base frequencies also get lower as you move from i5 to i7. And you have less GPU EU (80 -> 64).

Well, when your P is still quite E, I guess it’s a different equation :).
