Fragz' verdict
The Radeon RX 7900 XTX dominates this showdown, achieving a GPU score 200% higher than the RTX 3070. This substantial lead is reflected in our benchmarks, with the Radeon delivering vastly superior performance across all GPU scenes, such as 79.8 FPS in Earth II Vulkan compared to the RTX 3070's 25.9 FPS. The Radeon also features a significantly higher raw compute (ALU index of 803269) and a massive 24 GB of VRAM, though the RTX 3070 does offer higher memory bandwidth at 157 GB/s. For gamers, this translates to a much more powerful experience, capable of driving higher framerates in demanding titles. While the Radeon RX 7900 XTX's performance is impressive, it's based on a thin sample of just two verified runs, so bear that in mind. The RTX 3070, with its 8 GB of VRAM, still provides a capable gaming experience if top-tier performance isn't your only concern.

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
