Fragz' verdict
The RTX 5080 takes a clear lead over the RTX 4080 SUPER, outperforming it by 15.6% in overall GPU score. This performance uplift is evident across all our GPU-focused scenes, with the RTX 5080 delivering higher frame rates like 73.6 FPS in Earth II Vulkan compared to the RTX 4080 SUPER's 62.6 FPS, and 91.7 FPS versus 79.2 FPS in Mission to Earth II DX12. Its much higher raw compute, an ALU index of 800230 compared to 305965, and double the memory bandwidth at 330 GB/s contribute significantly to this difference. However, with only one verified run for the RTX 4080 SUPER and two for the RTX 5080, the sample sizes are quite thin, so these results should be viewed with some uncertainty. For gamers not chasing the absolute peak performance, the RTX 4080 SUPER, with its identical 16 GB of VRAM, still offers strong capabilities.

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
