Live benchmark data
Not enough verified runs yet for a fair pool verdict — averages appear once each side has at least five.
Verdict — RTX 4090
If you already have one, keep it — it's still a top-tier card. If you're shopping used, weigh it against a new 5080; the used discount needs to be significant to justify the older architecture.
Verdict — RX 9070 XT
The best AMD card since the 6800 XT. Raster performance rivals the 5070 Ti; RT is closer than ever but still a step behind. FSR 4 finally competitive with DLSS at Quality settings.
