Recently introduced NVIDIA GeForce RTX 5090 mobile graphics cards demonstrate impressive performance, but, as tests have shown, they are 50 per cent inferior to desktop versions.

Here's What We Know

The main reason for this gap is the power limitation of notebook GPUs, which is around 150W, while desktop models reach 575W. This limitation is due to the need to maintain the compact size and power efficiency of laptops.

Despite this, the mobile RTX 5090 outperforms the previous RTX 4080 model by 15-30% in performance, especially when using DLSS and multi-frame image generation technologies. These features can significantly improve graphics quality and frame rates, making the graphics card attractive to gamers and content creators.

However, the performance gains between generations have been less significant than expected, prompting mixed reviews. The mobile RTX 5090 has 10,496 CUDA cores, significantly less than the desktop version (21,760 CUDA cores), but its Blackwell architecture provides improved AI and rendering capabilities.

The RTX 5090 graphics card is already available in new notebook models such as the Razer Blade 16 and Asus Strix Scar 18.
