Clock Speeds
The Core i9-12900K is very flexible when it comes to being able to choose the speed it runs at, letting you tweak only so many cores in use at one speed, and when the demands go over that threshhold you can back things off a little bit. We saw 5.5 GHz when a couple of cores were in use, and as the number of cores increased, the speeds only just dropped back a little to 5.3 GHz on the Performance Cores. The Efficiency Cores, as their name implies, were slower, but then you really have to be hammering it to utilise all it has to offer, and a different problem will occur which we’ll discuss in a few graphs time.
