The gap changes with resolution.
Graphics card differences grow with resolution, because higher resolutions load the GPU harder.
| Resolution | RTX 5090 | RTX 3090 | Difference |
|---|---|---|---|
| 1080p | 99 | 94 | +5% |
| 1440p | 100 | 97 | +3% |
| 4K | 100 | 97 | +3% |
In a real build with a Ryzen 5 9600X.
Specs alone don’t tell you which to buy. Here is what each one does when it’s actually paired up, at 1440p.
| Game (1440p, paired with the Ryzen 5 9600X) | RTX 5090 | RTX 3090 |
|---|---|---|
| League of Legends | 365 fps | 358 fps |
| Counter-Strike 2 | 313 fps | 308 fps |
| Grand Theft Auto V | 156 fps | 153 fps |
| Elden Ring | 128 fps | 125 fps |
| Cyberpunk 2077 | 98 fps | 95 fps |
| Starfield | 97 fps | 95 fps |

So which should you buy?
The RTX 5090 is faster, but the RTX 3090 is the better buy per dollar. Take the RTX 5090 only if you want the extra headroom and the price gap doesn't bother you.

Common questions.
Straight answers on the RTX 5090 versus the RTX 3090.
Is the RTX 5090 better than the RTX 3090?
Yes, but by less than the spec sheet suggests. At 1440p the RTX 5090 scores 100 against 97 for the RTX 3090 — roughly 3% faster. It also costs about $500 more at MSRP, so the question is whether that gap is worth the money for your build.
Does the RTX 5090 or RTX 3090 bottleneck a Ryzen 5 9600X?
Paired with a Ryzen 5 9600X at 1440p, the RTX 5090 build comes out balanced, and the RTX 3090 build comes out balanced. Being GPU-bound is the healthy outcome — it means the graphics card is the part working hardest.
Is it worth upgrading from the RTX 3090 to the RTX 5090?
Only if you are also lifting the rest of the build. The RTX 5090 is about 3% ahead at 1440p, and gaps like that shrink further at 4K where the GPU does more of the work. If you are upgrading from the RTX 3090 purely for frames, check the pairing first.
Which is better value, the RTX 5090 or the RTX 3090?
On performance per dollar at MSRP, the RTX 3090 wins. The RTX 5090 lists at $1999 for an index of 100, and the RTX 3090 at $1499 for 97.
