Ada Lovelace · 2023
The mobile RTX 4080 adapts Ada Lovelace for gaming laptops with 7,424 CUDA cores, 12GB of GDDR6, and a 192-bit bus delivering 432GB/s of bandwidth - a different balance of cores and memory than its desktop namesake, tuned for laptop power limits. It's one of the strongest mobile GPUs available, handling 1440p ultra and even 4K with DLSS 3 frame generation doing the heavy lifting.
Laptop makers set this chip's power limit individually, and the 150W figure here is just a representative configuration - actual performance will vary between laptops depending on how aggressively each one is tuned and cooled, even under the same model name.
DLSS 3's Frame Generation - a dedicated Optical Flow Accelerator inserting newly generated frames rather than just rendering them - is a big part of how this chip reaches 4K at all in a laptop chassis, building on the Super Resolution, DLAA and Ray Reconstruction that DLSS 2 cards already had. Hardware ray tracing cores complete the picture, so reconstructed lighting has real data to work from.
Laptop manufacturers configure this GPU's power limit (TGP) per model. The 150W figure above is a typical point within the chip's published TGP range - actual power limits, and real-world performance, can vary significantly between laptops using the same GPU name.
Strong 1440p/4K gaming and demanding creative workloads.
