Fragz' verdict
The RTX 4080 is the undisputed champion here, outperforming the GTX 1080 Ti by a staggering 339.1% in GPU score, claiming the top rank among our tested hardware while the 1080 Ti sits at rank 8. While the RTX 4080 has only two verified runs, its superior performance is clear across the board, delivering 63.1 FPS in Earth II Vulkan and 77.9 FPS in Mission to Earth II DX12, compared to the GTX 1080 Ti's 19.7 FPS and 23.6 FPS respectively. This immense leap is driven by its raw compute power, with an ALU index of 694483, 200 GB/s memory bandwidth, 16 GB of VRAM, and a peak clock of 2880 MHz, far exceeding the 1080 Ti's 212160 ALU index, 80 GB/s bandwidth, 11 GB VRAM, and 1923 MHz peak clock. Crucially, the RTX 4080 also brings modern features like ray tracing, mesh shaders, and VRS, which are absent on the GTX 1080 Ti, providing a more complete gaming experience for compatible titles. If you’re looking for a serious upgrade to handle demanding games, the RTX 4080 is the clear choice.

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
