Nvidia’s next-gen Blackwell laptop GPUs have been the subject of another leak, with a new claim that the GB203 chip, which is set to be the engine of the desktop RTX 5080 graphics card, will not only power the laptop RTX 5090, but also the mobile RTX 5080.
That said, the theory is that with the RTX 5080 notebook incarnation, as you’d expect, it’ll be very much cut-down for core count, but we could still get a much more powerful GPU than the RTX 4080 – which very much disappointed laptop gamers and creatives alike (especially with a weak sauce VRAM loadout of 12GB).
