Fouquin, a TechPowerUp reader, "accidentally" stumbled upon a Microsoft Surface Laptop Ultra prototype that ensconces an Nvidia RTX Spark N1X SoC.As a quick recap, the N1X is supposed to herald a generation of "AI laptops", meaning it's an alternative to the RTX Spark desktop, and to the Macbook Pro. This is due to the fact that they're all designs with large pools of unified memory and competent GPUs, making them suitable for non-datacenter AI work.
