Question about Intel Core i9-9900K - Tray
Can someone explain to me why the i9 9900k out of the box "only" clocks at 4.7 instead of the stated 5ghz on turbo?
Helpful answer
The turbo mode depends on the number of actively used CPU cores.
The line-up is as follows:
1-2 cores --> 5.0 GHz Turbo
4 cores --> 4.8 GHz Turbo
6-8 cores --> 4.7 GHz Turbo
If you are running applications that use multiple cores, Turbo is activated on all cores, but the number of cores used simultaneously determines the effective frequency increase. If you run an application that uses a maximum of 2 cores, you should get 5.0 GHz, unless the CPU gets too hot, in which case the performance is limited accordingly.
