Did This Guy Find a Surface Laptop Ultra Prototype on the Side of the Road? Maybe. Here Are Some Benchmarks
A forum user posted an informal review of a prototype Surface Laptop Ultra equipped with Nvidia's RTX Spark N1X, though the authenticity of the device's origin is uncertain. Benchmarks show the ARM‑based system delivering performance comparable to mid‑range x86 CPUs but lagging behind competing laptops such as the M5 MacBook Pro. The laptop’s build quality is solid and repairable, but its display suffers from local‑dimming and HDR banding issues.
- ▪The prototype features a 20‑core ARM CPU and a Blackwell GPU with 6,144 CUDA cores, running Nvidia's RTX Spark platform.
- ▪Cinebench 2026 scores of 5,771 (multicore) and 540 (single‑core) place its performance near an Intel Core Ultra 5 245KF or AMD Ryzen 7 9850X3D.
- ▪Display testing revealed weak local dimming, noticeable blooming, and color banding in HDR mode.
- ▪The chassis is sturdy with easy‑to‑remove screws, allowing simple SSD replacement.
- ▪Nvidia‑powered RTX Spark laptops are slated for a fall launch, making this an early engineering sample.

Opening excerpt (first ~120 words) tap to expand
A TechPowerUp forum user who claims to have "found" an engineering sample of an unreleased Microsoft Surface Laptop Ultra equipped with an Nvidia N1X chip has posted an informal review, giving us another look at Nvidia's new RTX Spark platform. Though we'll need to see more, initial impressions are middling at best.Nvidia showed off RTX Spark series of laptops at Computex, where Nvidia CEO Jensen Huang talked about reinventing the PC around a system designed for AI agents. The proof would always be in the pudding with such grand plans, and now we have details on how such a laptop might perform.
