Fragz' verdict
The Radeon RX 7900 XTX emerges as the clear victor in this comparison, leading the Arc A770 Graphics by a substantial 299% in GPU score. It's worth noting, however, that both cards have only 1-2 verified runs, so the sample size is thin. This performance gap is evident across our benchmarks, with the Radeon RX 7900 XTX delivering 79.8 FPS in Earth II (Vulkan) compared to the Arc A770 Graphics' 8.6 FPS, and significantly higher framerates in Mission to Earth II (DX12) and Earth II Landing (DX12 Ultimate). The Radeon RX 7900 XTX also boasts a much higher raw compute (ALU index of 803269 versus 125974), greater memory bandwidth at 122 GB/s, and more VRAM at 24 GB, all contributing to a smoother, more capable gaming experience at higher settings. For gamers seeking top-tier performance, the Radeon RX 7900 XTX is the superior choice for demanding titles. The Arc A770 Graphics, while supporting the same modern features like ray tracing, simply operates in a different performance class, potentially suiting a more budget-conscious build where raw power isn't the absolute priority.

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
