Core i5-2400S
Model frame rate limit of 51 FPS. That is roughly the fastest this processor can feed a graphics card in a modern AAA title, no matter which card you fit.
The Core i5-2400S is one of the slowest gaming processor in our database, with a model frame rate limit of 51 FPS.
With 4 cores and 4 threads it is below what modern games expect, so busy scenes stutter before the average frame rate shows a problem.
Frame Rate Limit in Popular Games
| Game (settings) | Most FPS the Core i5-2400S can feed |
|---|---|
| Cyberpunk 2077 (High, no ray tracing) | ~45 |
| Fortnite (High, DirectX 12) | ~65 |
| Call of Duty: Black Ops 6 (High) | ~55 |
| Counter-Strike 2 (High) | ~110 |
Modelled estimates with an unlimited graphics card, rounded to the nearest 5 FPS. Your real frame rate is the lower of this and what your card can render. See the methodology.
Best match at each resolution
| Resolution | Closest matched card | Estimated FPS |
|---|---|---|
| 1080p | GeForce GTX 1660 | 49 |
| 1440p | GeForce GTX 1080 | 51 |
| 4K | GeForce RTX 3070 Ti | 51 |
"Closest matched" means the two parts run out of headroom at about the same frame rate, so neither is obviously wasted. A faster card is still worth buying if you plan to raise the resolution later.
The cards it lands closest to
The 24 graphics cards whose frame rate limit sits nearest this processor's, fastest first. Anything faster than the top of this table is wasted on it at 1080p, and anything slower is a card it will never trouble. For any other combination, use the calculator.

Common Questions
Is the Core i5-2400S good for an RTX 5070?
It holds the card back at 1440p. In our model the Core i5-2400S tops out near 51 FPS while the RTX 5070 could reach about 106, leaving roughly 52% of the card unused. It is a reasonable pairing at 4K, where the card does more work per frame.
What is the best GPU for the Core i5-2400S?
At 1440p, the GeForce GTX 1080 is the closest match: the two run out of headroom at about the same frame rate, so neither is wasted. A faster card still makes sense if you play at 4K, where the processor matters less.
Is the Core i5-2400S still good for gaming?
For older or lighter games, yes. Its 51 FPS frame rate limit and 4 threads mean modern AAA games run, but it will limit any recent mid-range or better card.
Will the Core i5-2400S bottleneck an RTX 5080?
Yes, at 1440p. It leaves about 66% of the RTX 5080 unused in our model (51 FPS from the processor against 149 from the card). At 4K the gap shrinks a lot.
