Fragz' verdict
The Radeon RX 9070 XT emerges as the clear victor in this comparison, outperforming the RTX 3080 Ti by a solid 13.3% in overall GPU score. This lead translates directly to higher frame rates, particularly in the Earth II Vulkan scene where it hit 64.7 FPS compared to the RTX 3080 Ti's 42.4 FPS, with minor advantages also seen in DX12 titles. Despite the RTX 3080 Ti showing a higher raw compute with an ALU index of 497242 and significantly greater memory bandwidth at 290 GB/s, the Radeon RX 9070 XT leverages its 16 GB of VRAM to deliver superior gaming performance. For gamers prioritizing maximum FPS, the Radeon RX 9070 XT is the stronger contender. The RTX 3080 Ti, while trailing, still provides a capable gaming experience with robust features like ray tracing, mesh shaders, and VRS.

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
