Core i5-10400F bottleneck & gaming FPS

Ranked 168 of 201 desktop processors for gaming in our database (16th percentile). It can sustain roughly 85 fps in a typical AAA title regardless of resolution — that ceiling is what decides whether a graphics card is worth pairing with it.

Core i5-10400F FPS in popular games1080p, high

The frame rate this chip could sustain with an infinitely fast graphics card. It is almost the same at every resolution, because rendering more pixels gives the processor no extra work.

Best GPU for the Core i5-10400F1080p, high

Ranked by how little performance the pairing wastes. Anything much faster than the top entry will sit partly idle at this resolution — though it may still be worth it if you plan to move to 1440p or 4K.

Every row measured against the same graphics card, so the difference shown comes from the parts themselves rather than from unrelated systems.

Is the Core i5-10400F good for gaming?

Not for demanding modern titles. It ranks 168 of 201 for gaming and will be the limiting component in most pairings, capping frame rate before the graphics card runs out of capacity.

What GPU should I pair with a Core i5-10400F?

The closest match at 1080p is the Titan RTX, wasting only 0.1% of the combined potential at around 83 fps. Anything materially faster will sit partly idle at this resolution, though it can still be the right buy if you plan to move to 1440p or 4K.

Living with a Core i5-10400F

This processor sits in the lower part of the range and will be the limiting component in most modern pairings. Frame rates will be capped by the chip well before the graphics card runs out of capacity, and no graphics upgrade will change that.

If frame rates are the problem, this is where the money goes. Raising the resolution will not help here in the way it does for a graphics-limited system.

A small cache holds this chip back

12 MB of L3 is modest by current standards, and it costs this chip more in games than its clock speed suggests. Game engines walk large, scattered data structures, so a small cache means more trips to main memory and more stalls on the render thread. Memory speed and timings matter unusually much on a part like this.
