Following initial teasers positioning it as the most powerful mobile system in its history, Microsoft has officially revealed full specifications and availability details for the Surface Laptop Ultra at a press event in San Francisco. Designed specifically for artificial intelligence researchers, machine learning engineers, and software developers, Microsoft is categorizing its new flagship mobile workstation as a “builder class PC”, aiming the machine squarely at enterprise compute workloads rather than general consumer or gaming markets.

The Surface Laptop Ultra is built around a 15-inch Mini-LED PixelSense Ultra touchscreen featuring Microsoft’s signature 3:2 aspect ratio and an exceptional peak brightness rating of up to 2,000 nits. The CNC-machined aluminium chassis measures 18mm in thickness, weighs 2.04kg (4.5 pounds), and will be available in Platinum and Nightfall colour options.
Ergonomics and physical connectivity receive significant upgrades. The notebook incorporates an enlarged haptic touchpad that is 30 percent larger than standard 15-inch Surface laptops, alongside an expansive array of legacy and modern ports, including USB-C, USB-A, HDMI, a 3.5mm audio jack, and a full-sized SD card reader. Microsoft is also introducing “Magnetic Connect,” a new proprietary port interface that merges the breakaway safety of magnetic charging cables with the high-speed power delivery, video output, and data transmission capabilities of a standard USB-C jack.
Hardware performance is anchored by NVIDIA’s new RTX Spark platform. The Surface Laptop Ultra will ship in two core silicon tiers: a base model powered by an RTX Spark N1X chip with an 18-core CPU and up to 32GB of unified memory, and a top-tier variant featuring a 20-core CPU capable of supporting up to 128GB of unified memory. Internal storage scales up to 2TB on factory configurations, with Microsoft confirming that the SSD remains fully user-upgradable.

Engineered to push up to one petaflop of FP4 AI compute, the laptop incorporates a redesigned thermal cooling solution providing 2.5 times the dissipation capacity of previous Surface notebooks. Crucially for mobile developer workflows, Microsoft claims the Surface Laptop Ultra delivers 99 percent of its peak compute performance when running unplugged on battery power. In direct performance comparisons against Apple’s M5 Pro-equipped MacBook Pro, Microsoft claims the Ultra executes video generation tasks 6.2 times faster, image creation 4.3 times faster, and achieves a 2.1 times improvement in time-to-first-token LLM processing.
Pre-orders for the Surface Laptop Ultra are open immediately, with pricing starting at $2,599 for base configurations. For developers requiring desktop-class localized compute clusters beyond a mobile chassis, Microsoft simultaneously announced the Surface RTX Dev Box, a dedicated AI development station starting at $5,999.
