Fragz' verdict
The RTX 4080 SUPER has the higher GPU score, with a 64.5 % lead over the RTX 5070 Ti Laptop GPU. This desktop card performs better in heavy rendering passes across Vulkan, DX12, and DX12 Ultimate, meaning it copes better with heavy graphics in those APIs. While they share an equal memory bandwidth, the RTX 4080 SUPER provides 16 GB of VRAM compared to the 12 GB found on the laptop chip. Keep in mind that the RTX 4080 SUPER has only been measured in a single rig, so that number is less certain. However, the RTX 5070 Ti Laptop GPU is still the right pick when a lot is happening on screen because it is highest on ALU index.

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
