Fragz' verdict
The RTX 3080 Ti is the undisputed champion here, leading the Iris Xe Graphics by a colossal 3255.3% in GPU score. This overwhelming performance advantage is clear across all our benchmarks, with the RTX 3080 Ti hitting 42.4 FPS in Earth II Vulkan compared to the Iris Xe's 1.2 FPS, and achieving 53.7 FPS in Mission to Earth II DX12 versus a meager 3.2 FPS. This massive difference stems from its vastly superior raw compute with an ALU index of 497242 against 36706, a huge 290 GB/s of memory bandwidth compared to 5 GB/s, and 12 GB of dedicated VRAM where the Iris Xe has none. Furthermore, the RTX 3080 Ti offers modern features like ray tracing and mesh shaders, which are absent on the Iris Xe Graphics, providing a richer gaming experience. For serious gamers targeting anything beyond basic display output, the RTX 3080 Ti is the only viable option, as the Iris Xe Graphics is simply not built for demanding gaming.

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
