Fragz' verdict
Based on our benchmarks, the Radeon RX 7900 XTX takes a significant lead, outperforming the RTX 4070 Ti by 61.9% in overall GPU score. It's important to note, however, that the Radeon was measured in only two verified runs, and the RTX 4070 Ti in just one, so these results should be considered with that thin sample size in mind. The Radeon RX 7900 XTX delivered substantially higher frame rates across all our tests, hitting 79.8 FPS in Earth II Vulkan compared to the RTX 4070 Ti's 49.9 FPS, and reaching 101.6 FPS in Mission to Earth II DX12 against 62.1 FPS. This performance gap is backed by its higher raw compute with an ALU index of 803269 versus 568584, and double the VRAM at 24 GB compared to 12 GB. For gamers prioritizing raw power and VRAM capacity for demanding titles, the Radeon RX 7900 XTX appears to be the stronger card based on this data.

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
