Gaming index (Ryzen 7 9800X3D = 100) against the processors closest to it.
The Core i5-10400F scores 42 on our gaming index, where the Ryzen 7 9800X3D is 100. That puts it #99 of 238 processors we track, in C tier. It is an older or entry level chip. Fine for light games and mid-range cards, but a fast graphics card will often wait on it.
It has 6 cores and 12 threads, boosting to 4.3 GHz. Six cores is enough for almost every game, though it is the minimum you want for new releases.
The Core i5-10400F uses the LGA1200 socket, so it fits motherboards with that socket. The fastest chips we track on the same socket are Core i9-11900K and Core i9-10900K, which would be a drop-in upgrade without changing the motherboard.
It is rated at 65 W. That is easy to cool; a decent tower cooler is enough, and the box cooler works on some models.
At 1080p, where the processor matters most, the Core i5-10400F can feed a card up to the GeForce RTX 4060 Ti 16GB before it starts to hold the card back by more than 10 percent. At 1440p the limit moves to the GeForce RTX 5070. At 4K, where the card does most of the work, it can keep up with the GeForce RTX 5080. The full list of graphics cards for the Core i5-10400F has the options for each resolution.
The Core i5-10400F suits a mid-range gaming PC at 1080p. Pair it with a card from the same tier.
