Fragz' verdict
The RTX 5090 is the dominant performer in this comparison, showcasing a 492% lead over the Arc A770 Graphics in overall GPU score. It delivers dramatically higher frame rates across all our GPU tests, hitting 132.8 FPS in Earth II (Vulkan) where the Arc A770 Graphics managed 8.6 FPS, and 171.4 FPS in Mission to Earth II (DX12) compared to 35.2 FPS, along with 113 FPS in Earth II Landing (DX12 Ultimate) versus 31.6 FPS. This superior performance is driven by its substantially higher ALU index of 1020560, a memory bandwidth of 660 GB/s, 31 GB of VRAM, and a peak clock of 3112 MHz, significantly outpacing the Arc A770 Graphics' 125974 ALU index, 109 GB/s bandwidth, 16 GB VRAM, and lack of a recorded peak clock. It's important to note that the Arc A770 Graphics has only one verified run, making its sample size quite thin. While both cards support ray tracing, mesh shaders, and VRS, the RTX 5090 clearly dominates in raw gaming performance.

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
