Fragz' verdict
The RTX 4080 decisively takes the lead in this comparison, achieving a 44.9% higher GPU score than the RTX 5070. This performance advantage is clearly visible across our benchmarks, with the RTX 4080 hitting 62.9 FPS in Earth II Vulkan and 77.9 FPS in Mission to Earth II DX12, significantly outpacing the RTX 5070's 41.3 FPS and 51.7 FPS respectively. The RTX 4080 also offers a higher ALU index of 539839 and 16 GB of VRAM, providing a stronger foundation for demanding games, despite the RTX 5070 featuring a higher memory bandwidth of 241 GB/s. For gamers seeking top-tier performance and longevity, the RTX 4080, ranked 4th overall, is the superior choice. The RTX 5070, while still a capable card at rank 11, has a thin sample size of only 2 verified runs, and its 12 GB of VRAM and lower raw compute make it better suited for less intensive gaming needs.

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
