Intel i5-10400F

The Intel Core i5-10400F is a mid-range processor for desktops with six cores based on the Comet Lake architecture (CML-S, 4th generation of Skylake). The processor clocks at between 4.1 and 4.8 GHz and can execute up to 12 threads simultaneously thanks to Hyper-Threading. 

The processor is still manufactured in the old 14nm (14nm++) process.

The Comet Lake architecture is similar to Coffee Lake and offers the same features and is produced in the same 14nm process. Other than the improved clock rates, the memory controller now also supports faster DDR4-2933 RAM. More information on Comet Lake and all the models and articles on it can be found here.


Thanks to the high clock speeds (and possible TDP settings with most mainboards), the Core i5-10400F offers a good gaming performance and thanks to the 6 cores also a good application performance.


The integrated Intel UHD Graphics 630 iGPU is supposed to offer a similar performance as the UHD630 in the Core i7-9900K. As a  low-end solution it will only run current games smoothly at reduced details - if at all.

Power Consumption

Intel specifies the TDP at 65 Watts (PL1) but under full load up to 134 Watt are consumed (PL2) for up to 28 seconds (Tau).
