NVIDIA's GeForce RTX 5090 Mobile is the top-end RTX 50 Series graphics card for laptops. It is based on the new Blackwell architecture and boasts more VRAM than the previous-generation 4090 Mobile (24GB vs 16GB) as well as higher performance. However, as with all mobile-class GPUs, it is not as fast as the desktop video card with the same name. That is largely due to power limits, which in a notebook computer are limited by the internal battery and portable AC adapter.
Alongside the rise in performance and VRAM, the RTX 5090 Mobile also includes several major feature upgrades. There are improved video encoding and decoding capabilities, with added support for 4:2:2 chroma subsampling, as well as new generations of CUDA, tensor, and ray tracing cores. The graphics memory is also made up of new, high-speed GDDR7 memory.
