Fragz' verdict
The RTX 4080 SUPER is the clear winner, leading the RTX 3070 Laptop GPU by an impressive 192.7% in overall GPU score, though its sample size is currently thin with only two verified runs. This massive performance gap is evident across all our GPU benchmarks, with the RTX 4080 SUPER delivering more than triple the framerates in Earth II Vulkan, Mission to Earth II DX12, and Earth II Landing DX12 Ultimate. Its higher raw compute with an ALU index of 488299 compared to 202083, significantly faster peak clock speeds of 2790 MHz versus 1950 MHz, and double the VRAM at 16 GB contribute to its superior performance. For gamers, this translates to a vastly smoother experience at higher resolutions and settings, especially when pushing demanding titles. The RTX 3070 Laptop GPU, despite being ranked 24th out of 48, still offers decent gaming performance, but it's clearly outclassed by the power of the RTX 4080 SUPER.

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
