NVIDIA RTX 3080

NVIDIA's mobile RTX 3080 reworks the desktop card's Ampere architecture into a laptop-friendly 6,144 CUDA cores, 8GB of GDDR6, and a 256-bit bus delivering 448GB/s of bandwidth - a smaller core count than the desktop 3080 to fit inside a notebook's power envelope. It was the halo chip in many 2021-2022 gaming laptops, capable of 1440p high-to-ultra settings and solid ray tracing with DLSS.

As with other mobile Ampere chips, laptop makers set their own power limit (TGP) for this GPU, and 150W here is a representative figure rather than a fixed spec - some laptops run it cooler and slower, others push it harder for noticeably better frame rates. Check the specific model's TGP before comparing two "RTX 3080" laptops directly.

That DLSS support mentioned above is specifically DLSS 2 - AI Super Resolution, DLAA, and Ray Reconstruction, with Frame Generation not showing up until the next generation's Ada Lovelace chips. It also carries Resizable BAR support, letting the CPU access its VRAM in one block instead of smaller windows for a small but genuine speed gain.
