Fragz' verdict
The Radeon RX 9070 XT takes a clear win in this matchup, leading the RTX 4070 by 34.4% in overall GPU score. It consistently outperforms its rival across our gaming benchmarks, delivering 64.7 FPS in Earth II (Vulkan), 53.8 FPS in Mission to Earth II (DX12), and 49.4 FPS in Earth II Landing (DX12 Ultimate), compared to the RTX 4070's 34.3 FPS, 44.1 FPS, and 42.3 FPS respectively. This performance is backed by a higher ALU index of 442372 and a more generous 16 GB of VRAM on the Radeon, offering more raw compute power and memory headroom for demanding titles, despite the RTX 4070's higher memory bandwidth of 133 GB/s. However, it's worth noting that the RTX 4070's data comes from only two verified runs, suggesting the sample size is quite thin, while the Radeon RX 9070 XT has a more robust seven runs.

What the numbers mean
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
