Nvidia's RTX Spark chip powers the Microsoft Surface Ultra AI laptop

Microsoft's got a new Surface coming, and it's the most powerful laptop the company's ever made.

Announced at Computex 2026, the Microsoft Surface Ultra comes with an Nvidia RTX Spark, a new all-purpose PC chip from the graphics chip giant.

In a press release, Microsoft called the Ultra all sorts of otherworldly superlatives, calling it a laptop for "world makers," but what that translates to is an extremely powerful workhorse laptop capable of running complex (you guessed it) AI tasks.

On the surface (sorry), the Surface Ultra is a pretty regular 15-inch laptop designed for professionals, with a mini-LED display, a ton of ports, and an extra-large touchpad. It weighs under 4.5 pounds, and has "all-day battery life," says Microsoft, though not all specs are available at this point.

What's inside is what makes this one interesting. First, there's the RTX Spark, Nvidia's new chip for PCs. It appears to be a variant of the GB10 chip, which powers Nvidia's miniature DGX Spark supercomputer announced in January 2025. It comes with 6,144 Blackwell GPU cores, 20 CPU cores, and offers 1 petaflop total of AI performance. You can configure the Ultra with up to 128GB of RAM, making it a portable AI supercomputer (that's also pretty great at regular office and gaming tasks).

In AI terms, the Microsoft Surface Ultra should be able to run 120 billion-parameter models locally. For reference, that's on par with a Mac mini equipped with 128GB of RAM.

There's no word on pricing, and the Surface Ultra isn't arriving until the fall.

It's not the only Nvidia RTX Spark computer that's coming, though. For this one, Nvidia has partnered with basically every Windows PC maker under the sun, including Dell, Asus, HP, and Lenovo; those are all also coming this fall.
