Core i9-11900KF
Model frame rate limit of 134 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 i9-11900KF is a mid-range gaming processor in our database, with a model frame rate limit of 134 FPS.
With 8 cores and 16 threads it has room to game and stream at the same time.
It uses the LGA 1200 socket with DDR4 memory, and at 1440p it can keep up with a card as fast as the GeForce RTX 5070 Ti.
Frame Rate Limit in Popular Games
| Game (settings) | Most FPS the Core i9-11900KF can feed |
|---|---|
| Cyberpunk 2077 (High, no ray tracing) | ~115 |
| Fortnite (High, DirectX 12) | ~170 |
| Call of Duty: Black Ops 6 (High) | ~145 |
| Counter-Strike 2 (High) | ~295 |
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 RTX 5070 | 134 |
| 1440p | Radeon RX 7900 XTX | 134 |
| 4K | GeForce RTX 5090 | 134 |
"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 i9-11900KF good for an RTX 5070?
Yes. At 1440p the RTX 5070 is the limit, not the Core i9-11900KF, at around 106 FPS in our model. That is the balance you want in a gaming PC.
What is the best GPU for the Core i9-11900KF?
At 1440p, the Radeon RX 7900 XTX 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 i9-11900KF still good for gaming?
Yes, for most builds. Its 134 FPS frame rate limit is plenty for 60 to 144 Hz gaming with a mid-range card, though it will hold back a high-end card at 1080p.
Will the Core i9-11900KF bottleneck an RTX 5080?
Yes, at 1440p. It leaves about 10% of the RTX 5080 unused in our model (134 FPS from the processor against 149 from the card). At 4K the gap shrinks a lot.
