Fragz' verdict
The Radeon RX 7900 XTX emerges as the dominant force in this comparison, leading the GTX 1080 Ti by a massive 472.9% in GPU score. This substantial performance gap is reflected across our benchmarks, with the Radeon delivering 79.8 FPS in Earth II (Vulkan) compared to the GTX 1080 Ti's 19.7 FPS, and a much higher 101.6 FPS in Mission to Earth II (DX12) versus 23.6 FPS. The Radeon RX 7900 XTX also boasts a significantly higher ALU index of 803269, 24 GB of VRAM, and 122 GB/s of bandwidth, alongside support for ray tracing, mesh shaders, and VRS, which the GTX 1080 Ti does not offer. While the Radeon card has only two verified runs in our data, the overwhelming performance advantage is clear. The GTX 1080 Ti, ranked 26th overall, is a much older card that could only be considered if budget is extremely tight and you're willing to sacrifice modern features and high framerates.

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
