Microsoft has entered new hardware territory with the release of the Surface Laptop Ultra, a high-end flagship notebook designed around NVIDIA's new RTX Spark platform. Equipped with up to 128GB of unified memory and an Arm-based system-on-a-chip, the device is marketed directly toward power users and AI enthusiasts who want robust local processing capabilities. Starting at $2,599 for the base configuration, the laptop positions itself at the premium end of the Windows ecosystem, though fully upgraded models equipped with top-tier RTX Spark hardware and expanded RAM can scale significantly higher.
Key takeaways
- The Surface Laptop Ultra is a flagship device powered by NVIDIA's RTX Spark Arm-based chip.
- It features a 15-inch Mini-LED display with a 3:2 aspect ratio and up to 2,000 nits of HDR brightness.
- The base model starts at $2,599, with review configurations reaching $3,700 and higher.
- It delivers strong multi-threaded performance and gaming capabilities, though it trails Apple's M5 Pro in benchmarks.
Design, display, and unique hardware features
Sporting an all-metal aluminum case, the Surface Laptop Ultra maintains a clean, professional aesthetic that resists fingerprints better than competing notebooks like the ASUS ProArt P16. However, at 4.4 pounds, it carries some heft compared to rivals like the 3.65-pound Dell XPS 16 or the 4-pound 16-inch MacBook Pro. The 15-inch screen utilizes a tall 3:2 aspect ratio and delivers up to 2,000 nits of HDR brightness via its Mini-LED panel, providing vibrant colors and deep contrast for media consumption and gaming.
Microsoft has also integrated a clever magnetic USB-C charging cable, which snaps securely into place while safely detaching if someone trips over the cord. Connectivity options include three USB-C ports, an HDMI port, an SD card slot, a headphone jack, and crucially, a traditional USB Type-A port for older peripherals. The keyboard retains the satisfying depth and feedback of previous Surface models, accompanied by a large trackpad featuring modern haptic feedback for Windows interface navigation.
Performance, AI capabilities, and battery life
At the core of the Surface Laptop Ultra is the NVIDIA RTX Spark chip, featuring unified memory accessible by both the 18-core or 20-core CPU and the massive GPU array. This architecture allows the system to run large local AI models, such as Qwen3.6 35B-A38 via OpenClaw, enabling tasks like audio transcription and agentic workflows. For gaming, the NVIDIA GPU cores deliver performance comparable to an RTX 5070 laptop GPU, pushing impressive frame rates in titles like Cyberpunk 2077 at 1440p using DLSS upscaling.
In benchmark testing, the RTX Spark chip excelled in multi-threaded tasks like Cinebench 2024, scoring 1,553 points, though it lagged behind Apple's M5 Pro chip, which scored 2,188 points in the same test. Single-threaded performance similarly favored Apple silicon. Despite benchmark discrepancies, the Surface Laptop Ultra excels in endurance, lasting an impressive 13 hours and 25 minutes in the PCMark 10 battery benchmark and comfortably pushing through roughly seven and a half hours of heavy daily office work.
