This could be Windows’ M1 moment — but expect it to cost a ton

Nvidia’s announcement that it’s getting into the consumer laptop chip space with RTX Spark is huge. Apple has proved for years that Arm-based chips can perform incredibly well while also delivering great battery life — at least on the Mac. In the Windows world, performance hasn’t fully matched up under Qualcomm chips, mostly in the graphics department. There’s clearly still untapped potential, and Nvidia seems to be promising to deliver it.

This could be Windows’ moment to blow us away with a new generation of supremely capable chips, much like Apple’s back in 2020, with the introduction of the M1. But why does this launch feel simultaneously exciting and fraught in 2026?

The Nvidia RTX Spark sounds like a monster of a laptop chip: 20 CPU cores, 6,144 GPU CUDA cores, and 128GB of unified LPDDR5X memory. Its integrated graphics are said to be equivalent to an RTX 5070 Laptop GPU — though Nvidia notably has shown nothing of performance metrics or actual benchmarks. As my colleague Sean Hollister pointed out, it’s basically a GB10 chip from Nvidia’s DGX Spark mini-PC. Nvidia calls it a “superchip” and “the most efficient PC chip ever built,” while Microsoft is billing its Spark-equipped Surface Laptop Ultra as “the most powerful thing we’ve ever made.”

It should surprise no one that Nvidia CEO Jensen Huang spent most of his time introducing RTX Spark laptops talking…
