Can someone please explain core speed and usage to me?
Most reviewers and outlets are saying that Intel's i9-9900K will perform as follows: 1/2 cores at 5 GHz, 1/2 cores at 4.8 GHZ, 4 cores at 4.7 GHZ. Then they mention that when running out of the box all cores run at 4.7 GHz which presumably means all cores plus the 8 threads? Then on OC3D Tom Logan keeps mentioning how 1 core boosts to 5 GHz and the others to 3.7 GHz and when overclocked easily go up by 1.3 to hit 5 GHz on all cores.
NB: Incidentally most places are saying you need liquid nitrogen to maintain a stable clock and Tom thinks it's the job of a normal decent CLC AIO. How can opinions vary so much when you're dealing with a piece of technology, they're not discussing Existentialism's role in the Third Reich, they should have pretty objective opinions on this stuff right?
I've managed to clock all cores on my i7-7820X to 4.3 as out of the the box they obviously performed all over the shop due to Intel Speedstep and Turboboost 3.0 tech etc.
What exactly is happening in these scenarios so I can understand it all if someone doesn't mind explaining it. I understand that they are better chips and cores that work better but how does one reviewer get 3.7 GHz on all cores and others a lot higher.
