Microsoft Laptop with Nvidia RTX Spark Leaked and Benchmarked Before Launch

Early tests found the prototype lags Apple’s M5 Pro and draws 12-23W at idle after Nvidia’s developer preview drivers, Fouquin said.

  • Tech enthusiast Fouquin published early benchmarks for a prototype Microsoft Surface Laptop Ultra, which he allegedly found near Redmond, Washington, in mid-June. The device features an Nvidia RTX Spark N1X APU with a 20-core Arm CPU.
  • Microsoft unveiled the 15-inch notebook at Computex in June alongside Nvidia's presentation, positioning it as the most powerful Surface device yet. The prototype Fouquin tested remains an engineering sample with 6,144 CUDA cores and up to 128GB of unified memory.
  • Benchmark results indicate the Surface Laptop Ultra lags behind competitors like the flagship MacBook Pro. Fouquin noted display issues including lackluster local dimming and color banding, alongside increased idle power draw from 7-8W to 12-23W after installing recent Nvidia RTX Spark developer preview drivers.
  • Fouquin predicts a starting price of at least $2,800, with top configurations reaching around $4,500. Laptop OEMs plan to launch notebooks equipped with Nvidia's new RTX Spark processors later this year, with Microsoft's Surface leading the rollout.
  • Sega confirmed that 2027's Virtua Fighter Crossroads will natively support the RTX Spark, with other titles including Alien: Isolation 2 and Total War: Warhammer 40,000 expected to follow. Gaming ecosystem support signals broader adoption momentum.

A perfectly functional prototype of the device has been recovered on "the edge of a road" by a user of the TechPowerUp forum... which has thus been able to test it in depth before everyone else.
