Fragz' verdict
The RTX 4080 is the clear winner in this GPU comparison, outperforming the Arc A770 Graphics by a substantial 205.8% in GPU score. It's important to note that the Arc A770 Graphics only has 1 verified run in our system, so its results should be viewed with some uncertainty compared to the RTX 4080's 5 runs. The RTX 4080 delivers significantly higher frame rates, clocking 62.9 FPS in Earth II (Vulkan) against the Arc A770 Graphics' 8.6 FPS, 77.9 FPS in Mission to Earth II (DX12) compared to 35.2 FPS, and 67.3 FPS in Earth II Landing (DX12 Ultimate) over 31.6 FPS. This superior performance is backed by a peak clock of 2895 MHz, a much higher raw compute with an ALU index of 539839, and memory bandwidth of 195 GB/s, significantly outpacing the Arc A770 Graphics' 125974 ALU index and 109 GB/s. For gamers, this means the RTX 4080 offers a much smoother and more responsive experience in demanding titles, consistently delivering higher frame rates across our test suite.

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
