Fragz' verdict
The RTX 5080 emerges as the clear victor in this comparison, outscoring the RTX 5070 by a significant 67% in overall GPU performance. Based on our thin sample of two verified runs for each card, the RTX 5080 consistently delivers superior frame rates, achieving 73.6 FPS in Earth II Vulkan and 91.7 FPS in Mission to Earth II DX12, compared to the RTX 5070's 41.3 FPS and 51.7 FPS. This substantial lead is supported by its much higher raw compute, boasting an ALU index of 800230, faster memory bandwidth at 330 GB/s, and a larger 16 GB of VRAM compared to the RTX 5070's 12 GB. For gamers, this means a notably smoother and more performant experience, especially at higher resolutions or in graphically intensive games. While the RTX 5070 remains a solid option, the RTX 5080 is the undeniable choice for those seeking top-tier gaming power.

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
