The reason we test games in CPU reviews at lower resolutions such as 720p and below is simple; titles are more likely to be CPU bound than they are GPU bound at lower resolutions. This means there are more frames for the processor to process as opposed to the graphics card doing the majority of the heavy lifting.
There are some variances where some games will still use graphical power, but not as much CPU grunt at these smaller resolutions, and this is where we can show where CPU limitations lie in terms of gaming.
We are using DDR5 memory on the Core i9-14900KS, as well as the other Intel 14th Gen Core series processors including the Core i9-14900K, the Core i7-14700K, Core i5-14600K, and Intel's 13th Gen at the relative JEDEC settings. The same methodology is also used for the AMD Ryzen 7000 series and Intel's 12th Gen (Alder Lake) processors. Below are the settings we have used for each platform:
- DDR5-5600B CL46 - Intel 14th & 13th Gen
- DDR5-5200 CL44 - Ryzen 7000
- DDR5-4800 (B) CL40 - Intel 12th Gen
Civilization VI
World of Tanks
Borderlands 3
Red Dead Redemption 2
F1 2022
Hitman 3
Total War: Warhammer 3
At 720p and lower, the CPU tends to play a more important role in affecting performance, and for the most part, the Core i9-14900KS with the fast frequencies can be utilized effectively. There's still not much difference between the Core i9-14900KS and the i9-14900K, though, especially not for the $100 premium that the KS commands.
