Fragz' verdict
The RTX 5080 is the clear winner here, though its component score is based on a thin sample of only 2 verified runs. It outperforms the RTX 3060 Ti by a massive 221% in overall GPU score, ranking 3rd among all measured GPUs. This significant lead is evident across all measured scenes, with the RTX 5080 delivering 73.6 FPS in Earth II Vulkan compared to the RTX 3060 Ti's 20.5 FPS, and 91.7 FPS in Mission to Earth II DX12 versus 27.2 FPS. Its raw compute power is also significantly higher, boasting an ALU index of 800230 compared to 211717, backed by a higher peak clock of 3000 MHz, nearly double the memory bandwidth at 330 GB/s, and double the VRAM at 16 GB. For gamers, this translates to a vastly smoother experience at higher resolutions and settings. The RTX 3060 Ti, however, still offers a solid gaming experience for those on a tighter budget, particularly at 1080p, with 8 GB of VRAM and full support for ray tracing, mesh shaders, and VRS.

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
