Fragz' verdict
The RTX 4080 is the clear victor in this head-to-head, boasting a 70.8% lead over the RTX 4070 in overall GPU score. This performance advantage is reflected across our benchmarks, with the RTX 4080 achieving 62.9 FPS in Earth II (Vulkan) and 77.9 FPS in Mission to Earth II (DX12), significantly higher than the RTX 4070's 34.3 FPS and 44.1 FPS, respectively. The RTX 4080 also packs more raw compute power, indicated by its ALU index of 539839, higher memory bandwidth at 195 GB/s, and a larger 16 GB of VRAM, compared to the RTX 4070's 12 GB and 133 GB/s. For gamers seeking maximum performance and smoother gameplay at higher resolutions, especially with its 5 verified runs providing a solid sample, the RTX 4080 is the undisputed champion. However, the RTX 4070, while based on only 2 verified runs, still offers respectable performance, making it a viable option if extreme frame rates aren't the absolute priority.

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
