Does the Core i5-10400F bottleneck the RTX 4060?

At 1440p the RTX 4060 is clearly the limiter (40% GPU-bound). That is fine as long as 73 fps meets your target; if not, the graphics card is the part to upgrade. Full breakdown at all three resolutions below, with estimated FPS in 14 games and which part to upgrade first.

Verdict: mild CPU bottleneck at 1080p, GPU-bound at 1440p, heavily GPU-bound at 4K

At 1080p the Core i5-10400F is the limiter by a small margin (12%). The RTX 4060 has a little headroom, which mostly shows up as slightly lower 1% lows rather than a lower average.

At 4K the RTX 4060 is heavily GPU-bound (76%). The Core i5-10400F has a lot of unused headroom, so a much faster graphics card would pay off without touching the processor.

The pattern is the classic one: the Core i5-10400F limits at 1080p, the RTX 4060 limits at 4K, and 1440p sits in between. If you play at 1080p on a high-refresh monitor, the processor matters more than the card here.

The ceilings are what each part could deliver alone in a typical modern AAA game. The lower one is your frame rate; the gap is the bottleneck. In 10 of 14 games the Core i5-10400F is the 1080p limiter by 10% or more.

This pair reaches 144 fps at 1080p in 7 of 14 games and 60 fps at 4K in 6 of 14. Competitive titles use their usual reduced settings; capped games show their cap.

Which part to upgrade first

The graphics card first. Moving to a RTX 5060 ($300–400 class) lifts the 1440p estimate from 73 to about 84 fps; a faster processor adds almost nothing because the RTX 4060 is the limiter at this resolution.

The general rule by resolution is in upgrade CPU or GPU first.

Cheaper or better alternatives

Pairings at a similar total price ($300–400 class for the pair) that are as balanced or better at 1440p.

Settings that reduce this bottleneck

Because the RTX 4060 is the limiter, every heavy graphics setting buys frames: drop ray tracing first, then shadows, volumetric effects and ambient occlusion, and use DLSS/FSR quality mode before touching texture quality. The processor has 40% headroom, so none of this will shift the limit to the CPU until you are well above the current frame rate. See how to fix a GPU bottleneck.

Core i5-10400F + RTX 4060 FAQ

Is the Core i5-10400F good enough for the RTX 4060 at 1440p?

At 1440p the RTX 4060 is clearly the limiter (40% GPU-bound). That is fine as long as 73 fps meets your target; if not, the graphics card is the part to upgrade.

What FPS will the Core i5-10400F and RTX 4060 get in Marvel Rivals?

About 104 fps at 1080p, 55 fps at 1440p and 23 fps at 4K at the settings on the methodology page, limited by the graphics card at 1440p. It is the most demanding title in our set, so it is the floor for this pair.

Would a faster processor help the RTX 4060?

No listed processor adds a meaningful amount of frames at 1440p; the RTX 4060 is the part to change.

Is the RTX 4060 overkill for the Core i5-10400F?

No. The Core i5-10400F feeds the RTX 4060 well at 1080p (12% CPU-bound) and the card becomes the limiter as the resolution rises, which is exactly what you want.
