Make sure you are running Windows 11 to get full performance from this CPU, Difference between the F/K/KF/KS e.t.c. is speed & built in graphics, this has no built in graphics but does have speed. Seems to be slightly easier to cool than the K/KS model. Bit slower than my 5900x at video conversion literally a few seconds but a decent improvement in frames in gaming & even in game design using Unreal Engine 5 you notice an improvement. In hindsight a CPU with the built in graphics might be a better option in my case but I still have the same performance so I have no complaints.
