Fragz' verdict
The RTX 5080 clearly takes the win here, leading the Arc A770 Graphics by a massive 252.3% in GPU score, though both cards have very thin sample sizes with only one or two verified runs each. Across our GPU scene tests, the RTX 5080 delivered significantly higher frame rates, scoring 73.6 FPS in Earth II Vulkan compared to the Arc A770 Graphics' 8.6 FPS, and 91.7 FPS in Mission to Earth II DX12 versus 35.2 FPS. This performance gap is backed by its raw compute power, with the RTX 5080 showing an ALU index of 800230 and 330 GB/s of memory bandwidth, far exceeding the Arc A770 Graphics' ALU index of 125974 and 109 GB/s bandwidth. For gamers, this means the RTX 5080 will offer a substantially smoother and more responsive experience, particularly in demanding titles utilizing modern APIs. While the Arc A770 Graphics offers the same 16 GB of VRAM and supports all the latest graphics features like ray tracing, mesh shaders, and VRS, its overall performance numbers suggest it's in a completely different league, making it hard to recommend over the RTX 5080 based on these scores alone.

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
