Laptop OEMs are set to begin launching notebooks equipped with Nvidia's RTX Spark processors later this year, with Microsoft's new flagship Surface leading the pack. TechPowerUp Forum user "Fouquin" claims to have found a prototype Microsoft Surface Laptop Ultra lying on the side of the road near Microsoft's Redmond, Washington headquarters in mid-June. Fouquin initially tested the laptop on drivers dated November 2025, then repeated his tests after Nvidia released the RTX Spark developer preview drivers last week. The Phoronix Test Suite, Blender, and Cinebench suggest that RTX Spark lags behind Apple's M5 Pro chip. Microsoft unveiled the Surface Laptop Ultra alongside Nvidia's RTX Spark presentation at Computex in June, calling the 15-inch notebook the most powerful Surface device yet.
