The gap changes with resolution.
Graphics card differences grow with resolution, because higher resolutions load the GPU harder.
| Resolution | RTX 5070 | RTX 3080 | Difference |
|---|---|---|---|
| 1080p | 91 | 84 | +8% |
| 1440p | 89 | 83 | +7% |
| 4K | 89 | 83 | +7% |
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 5070 | RTX 3080 |
|---|---|---|
| League of Legends | 341 fps | 328 fps |
| Counter-Strike 2 | 294 fps | 284 fps |
| Grand Theft Auto V | 145 fps | 139 fps |
| Elden Ring | 117 fps | 111 fps |
| Cyberpunk 2077 | 90 fps | 85 fps |
| Starfield | 90 fps | 86 fps |

Common questions.
Straight answers on the RTX 5070 versus the RTX 3080.
Is the RTX 5070 better than the RTX 3080?
Yes, but by less than the spec sheet suggests. At 1440p the RTX 5070 scores 89 against 83 for the RTX 3080 — roughly 7% faster.
Does the RTX 5070 or RTX 3080 bottleneck a Ryzen 5 9600X?
Paired with a Ryzen 5 9600X at 1440p, the RTX 5070 build comes out balanced, and the RTX 3080 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 3080 to the RTX 5070?
Only if you are also lifting the rest of the build. The RTX 5070 is about 7% 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 3080 purely for frames, check the pairing first.
Which is better value, the RTX 5070 or the RTX 3080?
On performance per dollar at MSRP, the RTX 5070 wins. The RTX 5070 lists at $549 for an index of 89, and the RTX 3080 at $699 for 83.
