Fragz' verdict
The RTX 5080 is the clear winner in this comparison, boasting a massive 251.8% lead in GPU score over the RTX 3070 Laptop GPU. This translates directly into gaming performance, with the RTX 5080 delivering significantly higher frame rates across all GPU tests, such as 73.6 FPS in Earth II Vulkan compared to the RTX 3070 Laptop's 18.5 FPS. Its superior raw compute with an ALU index of 800230, higher peak clock of 3000 MHz, and double the VRAM at 16 GB provide a substantial boost for a much smoother experience. While the RTX 3070 Laptop GPU still offers a solid gaming experience for its class, the RTX 5080 is in a league of its own for high-end gaming, though its performance is based on a thin sample of only two verified runs.
Generated September 30, 2026 from the 8 verified runs available then. The verdict is never silently rewritten — new numbers get a new verdict.
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
