Fragz' verdict
The Radeon RX 7900 XTX dominates this comparison, outperforming the Arc 140T GPU (8GB) by a massive 982.6% in GPU score. This substantial lead is evident across all our GPU benchmarks, with the Radeon card delivering 79.8 FPS in Earth II (Vulkan), 101.6 FPS in Mission to Earth II (DX12), and 89.5 FPS in Earth II Landing (DX12 Ultimate), while the Arc card managed only 5 FPS, 9.7 FPS, and 10.5 FPS respectively. Digging into the hardware, the Radeon RX 7900 XTX boasts a significantly higher ALU index of 803269, 122 GB/s of memory bandwidth, and 24 GB of VRAM, compared to the Arc's ALU index of 137105, 17 GB/s bandwidth, and 0 GB of VRAM. For a gamer, this means the Radeon RX 7900 XTX offers a premium, high-performance experience, while the Arc 140T GPU (8GB) struggles to achieve playable frame rates in modern titles. However, it's worth noting that both cards have very thin sample sizes with only one verified run for the Arc and two for the Radeon, which introduces some uncertainty into these results.

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
