The gap changes with resolution.
Graphics card differences grow with resolution, because higher resolutions load the GPU harder.
| Resolution | RTX 2080 | RX 6600 | Difference |
|---|---|---|---|
| 1080p | 39 | 39 | 0% |
| 1440p | 40 | 36 | +11% |
| 4K | 43 | 38 | +13% |

So which should you buy?
The RTX 2080 is faster, but the RX 6600 is the better buy per dollar. Take the RTX 2080 only if you want the extra headroom and the price gap doesn't bother you.

Common questions.
Straight answers on the RTX 2080 versus the RX 6600.
Is the RTX 2080 better than the RX 6600?
Yes, but by less than the spec sheet suggests. At 1440p the RTX 2080 scores 40 against 36 for the RX 6600 — roughly 11% faster. It also costs about $370 more at MSRP, so the question is whether that gap is worth the money for your build.
Does the RTX 2080 or RX 6600 bottleneck a Ryzen 5 9600X?
Paired with a Ryzen 5 9600X at 1440p, the RTX 2080 build comes out 35% GPU-bound, and the RX 6600 build comes out 35% GPU-bound. Being GPU-bound is the healthy outcome — it means the graphics card is the part working hardest.
Is it worth upgrading from the RX 6600 to the RTX 2080?
Only if you are also lifting the rest of the build. The RTX 2080 is about 11% 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 RX 6600 purely for frames, check the pairing first.
Which is better value, the RTX 2080 or the RX 6600?
On performance per dollar at MSRP, the RX 6600 wins. The RTX 2080 lists at $699 for an index of 40, and the RX 6600 at $329 for 36.
