RTX 5090 vs RTX 5080
The RTX 5090 is about 40% faster than the RTX 5080 at 4K and 37% faster at 1440p.
Quick verdict: the RTX 5090 is the faster card. The RTX 5080 is only the smarter buy if you can get it for at least 27% less than the RTX 5090; any smaller discount and you are paying more per frame.

Estimated FPS at 1080p, 1440p and 4K
1080p: the RTX 5090 leads by 34%. 1440p: the RTX 5090 leads by 37%. 4K: the RTX 5090 leads by 40%. These figures come from our performance model, calibrated against published benchmark averages. They are estimates for comparing the two cards, not results measured on your PC.
Estimated FPS in Popular Games at 1440p
| Game (settings) | RTX 5090 | RTX 5080 |
|---|---|---|
| Cyberpunk 2077 (High, no ray tracing) | ~165 | ~120 |
| Fortnite (High, DirectX 12) | ~265 | ~195 |
| Call of Duty: Black Ops 6 (High) | ~235 | ~170 |
| Counter-Strike 2 (High) | ~490 | ~360 |
Per-game figures scale each card's modelled 1440p average by how demanding the game is relative to our test blend, rounded to the nearest 5 FPS. Counter-Strike 2 is usually limited by the processor well before these numbers.
Verdict: RTX 5090 or RTX 5080?
The RTX 5090 is a full performance tier faster than the RTX 5080: about 34% at 1080p, 37% at 1440p and 40% at 4K in our model. The gap narrows at 1080p because both cards are closer to what a typical processor can feed them, so the higher your resolution, the more of the difference you actually get.
The RTX 5090 carries 32GB of video memory against 16GB on the RTX 5080. Both have enough for current games at any resolution, so this one is mostly about future headroom.
At launch the RTX 5090 was $1,999 and the RTX 5080 $999, which works out to $9.8 and $6.7 per frame at 1440p. On those prices the RTX 5080 is the better value, but street prices move every week, so check before you buy. The RTX 5090 is rated for 215W more board power, which means more heat, more fan noise and possibly a bigger power supply.
Bottom line: the RTX 5090 is the faster card. The RTX 5080 is only the smarter buy if you can get it for at least 27% less than the RTX 5090; any smaller discount and you are paying more per frame.
Pairing Either Card With a Processor
A faster graphics card only helps if the processor can keep up. Each card's own page lists the slowest CPU that will not hold it back at every resolution:
- GeForce RTX 5090: best CPU pairing and bottleneck
- GeForce RTX 5080: best CPU pairing and bottleneck
- Check your own processor in the bottleneck calculator
Power supply: a common rule of thumb is the card's board power plus about 150W for the rest of a gaming PC, with 30% headroom. That points to roughly 950W for the RTX 5090 and 700W for the RTX 5080. Check the card maker's own recommendation too.
