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 2.9 and 4.3 GHz and can execute up to 12 threads simultaneously thanks to Hyper-Threading.
The processor is still manufactured on the old 14nm (14nm++) process.
The Comet Lake architecture is similar to Coffee Lake and offers the same features and is made with the same 14 nm process. Other than the improved clock rates, the memory controller now also supports faster DDR4-2666 RAM. More information on Comet Lake and all the models and articles on it can be found here.
Performance
The average 10400F in our database matches the Ryzen 7 4800U and also the Core i7-9700K in multi-thread performance to be a more than decent mid-range option for your gaming rig, as of early 2022.
Graphics
The CPUs with an "F" suffix do not feature an integrated graphics adapter. The Intel UHD Graphics 630 iGPU is deactivated.
Power consumption
This Core i5 has a default TDP (also known as the long-term power limit) of 65 W which is in line with most desktop chips.
The i5-10400F is built with one of the old 14 nm Intel processes for poor, as of mid 2023, energy efficiency.
The Intel Core i7-4790 is a high end quad-core desktop processor using the Haswell architecture. It clocks at 3.6 - 4 GHz and can run 8 threads at once thanks to HyperThreading. Compared to the similar named Core i7-4790K, the 4790 clocks a bit lower and offers no open multiplier for overclocking. The TDP is rated at 84 Watt and therefore suited for Desktop-PCs and large laptops.
