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.

Core i5-10400F + RTX 4060: change RAM, resolution or game
Data version 2026.09 · methodologyYour RTX 4060 tops out around 73 fps in Typical modern AAA game at 1440p, while your Core i5-10400F could feed it about 123. That is a 40% GPU bottleneck (significant) - the normal state for a gaming PC unless the frame rate is below your target.
Confidence: high. Estimates from benchmark indices, not a measurement of your PC. How this works.
Graphics cards that clear this bottleneck
Any of these keeps up with your Core i5-10400F at 1440p in Typical modern AAA game, so nothing is left idling. Cheapest first.
Past the first card your Core i5-10400F sets the ceiling at 1440p, so they all land on the same frame rate. The stronger ones only pay off if you move up in resolution too.Affiliate link: if you buy through it we may earn a commission at no extra cost to you.Your memory is not the problem.
16GB (2x8GB) DDR4-3200 is plenty for Typical modern AAA game. Do not let anyone sell you more RAM as an fps upgrade.
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.
Core i5-10400F + RTX 4060 bottleneck at 1080p, 1440p and 4K
| Resolution | CPU ceiling | GPU ceiling | Verdict | Est. fps |
|---|---|---|---|---|
| 1080p | 123 fps | 139 fps | 12% CPU | 123 |
| 1440p | 123 fps | 73 fps | 40% GPU | 73 |
| 4K | 123 fps | 30 fps | 76% GPU | 30 |
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.
