Fragz' verdict
The RTX 4080 is the undisputed champion in this comparison, boasting an incredible 8235.1% lead in GPU score over the UHD Graphics 770. This massive performance gap translates directly to gaming, with the RTX 4080 delivering 62.9 FPS in Earth II (Vulkan), 77.9 FPS in Mission to Earth II (DX12), and 67.3 FPS in Earth II Landing (DX12 Ultimate), while the UHD Graphics 770 struggles with less than 2 FPS in all tested scenes. The RTX 4080 dominates with a raw compute ALU index of 539839, 195 GB/s of bandwidth, 16 GB of dedicated VRAM, and a peak clock of 2895 MHz, supporting advanced features like ray tracing and mesh shaders that the UHD Graphics 770 lacks. While the UHD Graphics 770, measured with a thin sample of only 1 verified run, is clearly not built for serious gaming, it remains a viable option for basic desktop use where a dedicated graphics card isn't required.

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
