Fragz' verdict
The RTX 4080 is the clear winner in this comparison, leading the RTX 3070 Laptop GPU by an impressive 205.4% in overall GPU score. This massive performance gap is evident across all our GPU benchmarks, with the RTX 4080 delivering significantly higher frame rates, such as 62.9 FPS in Earth II (Vulkan) compared to the RTX 3070 Laptop GPU's 18.5 FPS. It also boasts superior raw compute with an ALU index of 539839, a higher peak clock of 2895 MHz, and double the VRAM at 16 GB, providing a smoother, more capable gaming experience. While the RTX 4080 offers top-tier performance, the RTX 3070 Laptop GPU, despite its lower rank of 24, still offers modern features like ray tracing and VRS, making it a viable option for gamers prioritizing portability and who aren't chasing the highest frame rates.

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
