Fragz' verdict
The RTX 5080 has the higher GPU score, with a 110.2 % lead over the RTX 5070 Ti Laptop GPU. You will see the RTX 5080 cope better with heavy graphics in Vulkan, DX12 and DX12 Ultimate because it delivers higher FPS in those scenes. Its ALU index shows more raw compute for your shaders and effects, while its 310 GB/s memory bandwidth helps it move data faster than the 163 GB/s seen on the other card. With 16 GB of VRAM, it can also hold more large textures and high resolutions compared to the 12 GB on the laptop GPU. The RTX 5080 is highest in every performance test we ran.

What the numbers mean
The headline score is the part's best measured run, and the measurements under it come from that same run. It shows what the part has been proven to do — not what an average rig gets out of it. 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
