Fragz' verdict
The Radeon RX 9070 XT emerges as the clear victor in this matchup, securing a substantial 28.3% lead in overall GPU score over the RTX 3080. This performance gap is visible across our tests, with the Radeon hitting a smooth 64.5 FPS in Earth II (Vulkan) compared to the RTX 3080's 37.5 FPS, and showing consistently higher frame rates in both Mission to Earth II (DX12) and Earth II Landing (DX12 Ultimate). While the RTX 3080 features a higher raw compute (ALU index) and a much wider 226 GB/s memory bandwidth, the Radeon leverages its larger 16 GB of VRAM to deliver superior scene performance. However, gamers should be aware that the RTX 3080's data is based on a thin sample of only two verified runs, suggesting its full capabilities might not be entirely captured.

What the numbers mean
The headline score is the part's best measured run, and the measurements under it come from that same run. It shows what the part has been proven to do — not what an average rig gets out of it. The GPU score is the graphics card's own performance — that is what we rank on. GAMING is the whole rig's score in the best PC we measured the card in, and depends on processor, memory and storage. We show both and never mix them.
All numbers come from our benchmark suite: four hand-built 3D scenes written directly against the graphics APIs in Rust, the same load on every PC. The methodology is open at https://whatfps.com/metodik
