Check igor for higher resolutions. Igor's test shows that even at higher resolutions Alder Lake is still the most efficient CPU gaming architecture by similar margins compared to low res. Alder Lake actually seems to benefit slightly as you go up in resolution as the CPU is stressed even less.Who games in 720p? If the 12th gen is DDR5 why in the world would you pair it with DDR4 3200?
But I agree the 12600K is the CPU. Intel scored greatly with it.
Edit: that's quite an in-depth review, thanks for the link!
Lower resolutions is the worst case for CPU power consumption and it reduces GPU bottlenecks.
