Fragz' verdict
The RTX 3080 Ti takes a dominant lead over the RTX 3070 Laptop GPU, outperforming it by 161.2% in overall GPU score. This massive performance gap is clear across our benchmarks, with the RTX 3080 Ti pushing 42.7 FPS in Earth II (Vulkan) and 53.7 FPS in Mission to Earth II (DX12), compared to the RTX 3070 Laptop GPU's 15 FPS and 19.6 FPS respectively. The 3080 Ti's significantly higher raw compute, indicated by its 499791 ALU index, alongside its 291 GB/s memory bandwidth and 12 GB of VRAM, explains its superior gaming capabilities. While the RTX 3070 Laptop GPU's single verified run means the sample is thin, its 8 GB of VRAM and 1725 MHz peak clock simply can't compete with the desktop card's power. For gamers prioritizing maximum performance, the RTX 3080 Ti is the clear winner, but the RTX 3070 Laptop GPU still offers a solid gaming experience for its class.

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
