Fragz' verdict
The RTX 5090 is the clear victor in this head-to-head, outperforming the RTX 3070 Laptop GPU by a substantial 491.3% in overall GPU score. This dominance is evident across our benchmarks, with the RTX 5090 delivering a significantly smoother experience, hitting 132.8 FPS in Earth II Vulkan and 171.4 FPS in Mission to Earth II DX12, compared to the 3070 Laptop GPU's 18.5 FPS and 24.1 FPS respectively. Hardware-wise, the RTX 5090 boasts a much higher raw compute with an ALU index of 1020560, memory bandwidth of 660 GB/s, and a massive 31 GB of VRAM, dwarfing the 3070 Laptop GPU's 202083 ALU index, 153 GB/s bandwidth, and 8 GB VRAM. For uncompromised gaming performance at the highest settings, the RTX 5090 is the superior choice. However, the RTX 3070 Laptop GPU remains a perfectly capable option for portable gaming, offering a solid experience within its form factor limitations.

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
