Fragz' verdict
The RTX 4080 SUPER takes a commanding win here, leading the Radeon RX 9070 XT by 26.7% in overall GPU score, though we must note the RTX 4080 SUPER’s results come from a very thin sample of just one verified run. This lead is largely driven by its strong performance in Mission to Earth II (DX12) and Earth II Landing (DX12 Ultimate) where it delivered significantly higher frame rates, alongside superior memory bandwidth at 163 GB/s. While the Radeon RX 9070 XT did show a higher ALU index and slightly better performance in Earth II (Vulkan), the RTX 4080 SUPER's higher component score and consistent lead in modern DirectX scenes generally point to a more powerful gaming experience. For gamers prioritizing overall performance in a wider range of titles, the RTX 4080 SUPER is the clear frontrunner, but those focused strictly on Vulkan performance might find the Radeon's slightly higher frame rate in that specific test appealing.

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
