Fragz' verdict
The Radeon RX 9070 XT takes a commanding lead over the Arc A770 Graphics, outperforming it by a massive 140.5% in overall GPU score. This translates to significantly higher frame rates, with the Radeon card hitting 64.7 FPS in Earth II (Vulkan) compared to the Arc's 8.6 FPS, and also showing strong leads in Mission to Earth II (DX12) and Earth II Landing (DX12 Ultimate). The Radeon's much higher raw compute, indicated by its 442372 ALU index compared to the Arc's 125974, is a major factor in its superior performance, enabling a smoother and more responsive gaming experience. While the Arc A770 Graphics does offer 16GB of VRAM and slightly higher memory bandwidth at 109 GB/s, its overall performance is considerably lower, though it's worth noting the data for the Arc is based on a very thin sample of just one verified run. For gamers prioritizing raw power and high frame rates, the Radeon RX 9070 XT is the clear choice based on these numbers.

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
