In the pursuit of more gaming power, a YouTuber has modded their Nvidia GeForce RTX 5090 laptop GPU, putting Nvidia’s mobile flagship through its paces and scoring a huge performance boost in the process. While it isn’t a mod we’d recommend trying yourself, it does show that Nvidia’s mobile GPUs aren’t always being pushed to their maximum potential.
RTX 5090 laptops have been trickling out over the last few months, and they’re certainly powerful, as our Razer Blade 16 review shows. That Razer model is now the top choice in our best gaming laptop guide, but comparing it to an RTX 5090-powered PC might be unfair. The RTX 5090 mobile GPU just isn’t as powerful as its desktop counterpart, with just over half the CUDA cores compared to the RTX 5090 desktop GPU, along with serious voltage and clock speed limitations.
