Fragz' verdict
The Radeon RX 7900 XTX is the clear winner here, leading the RTX 5070 by a substantial 89.1% in GPU score, though both components currently have only two verified runs, making the sample thin. This translates to significantly higher frame rates across our GPU benchmarks, with the Radeon hitting 79.8 FPS in Earth II Vulkan compared to the RTX 5070's 41.3 FPS, and 101.6 FPS in Mission to Earth II DX12 versus 51.7 FPS. The Radeon RX 7900 XTX also boasts a much higher raw compute (ALU index of 803269) and double the VRAM at 24 GB, which are key factors in its performance lead, despite the RTX 5070 having a higher memory bandwidth of 241 GB/s. For gamers prioritizing maximum performance and abundant VRAM for demanding titles, the Radeon RX 7900 XTX is the stronger card, securing a rank of 2 out of 48 measured GPUs. However, the RTX 5070 still delivers a respectable GPU score of 10006 and ranks 11th overall, making it a viable option for a different tier of gaming experience.

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
