CPU 12400 vs 12600K Power Limited to 65W - Any performance difference?

[SilverJS]

Hey all,

About to upgrade my SFF PC, and would like to keep the CPU PL'd at about 65W for thermals/acoustics. Has anybody in this space done any kind of testing to verify those two processors' (or equivalents) efficiency?

If I can expect a decent performance uplift, I don't mind shelling out for the 12600K (or even 13600K), but I'm wondering if it's worth it.

Cheers!

All else being equal, there is still going to be a difference because the 12600K has E-cores and the 12400 doesn't. If you want reduced power consumption and E-cores you could always get the 13400/13500.

My CPU has no e-Cores, but maybe this is of help to you:
At 4K with an undervolted RTX 3080, my i7-11700K @ 65 W provides the exact same framerates compared to 95 or 125 W.
I use Windows 10 x64 and tested Cyberpunk 2077, Ghostrunner and some older games (Dying Light 1, Mafia 3, Shadow of War, Shadow of the Tomb Raider, Forza 6 Apex, Final Fantasy 15 Benchmark).

so why buying a 125W CPU if you have to throttle it to 65W?
is cinebench also same at 65W compared to 125W?

Cinebench: multithread performance of course no, but it still beats the stock i9-12900K when set to 65 W, which is nuts I think. Singlethread performance @65 W is the same compared to 125 W.
