Fragz' verdict
The RTX 4080 is the undisputed champion in this matchup, leading the GTX 1080 by a colossal 519.8% in GPU score, though the GTX 1080's single verified run means we have a thin sample for that card. This performance gap is evident across all benchmarks, with the RTX 4080 delivering 62.9 FPS in Earth II (Vulkan) compared to the GTX 1080's 13.9 FPS, and 77.9 FPS in Mission to Earth II (DX12) versus 16.7 FPS. Furthermore, the RTX 4080 boasts a significantly higher ALU index of 539839, 195 GB/s of bandwidth, 16 GB of VRAM, and a peak clock of 2895 MHz, dwarfing the GTX 1080's 143867 ALU index, 57 GB/s bandwidth, 8 GB VRAM, and 1949 MHz peak clock. For gamers, this means a night and day difference in frame rates and the ability to utilize modern features like ray tracing, mesh shaders, and VRS, which the GTX 1080 lacks entirely. While the GTX 1080 is clearly outclassed for contemporary gaming, it remains a functional card for less demanding titles or if you're not chasing high frame rates and cutting-edge visual effects.

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
