Microsoft has officially revealed the Surface Laptop Ultra, its most powerful Surface laptop yet. First unveiled earlier this year, the 15-inch machine is aimed at developers, creators and AI researchers who need workstation-class computing in a portable form factor.

The Surface Laptop Ultra is built around Nvidia's RTX Spark platform and supports configurations with an 18-core or 20-core CPU. Graphics are based on Nvidia's Blackwell architecture with up to 6,144 GPU cores. Microsoft says the system can deliver up to one petaflop of FP4 AI compute and supports up to 128GB of unified memory.

Hardware built for local AI

The display is a 15-inch Mini-LED PixelSense Ultra touchscreen with a 3:2 aspect ratio and up to 2,000 nits of peak brightness. Microsoft also highlights a large haptic touchpad, about 30% larger than those found on typical 15-inch Surface laptops.

Storage tops out at 2TB and the SSD can be replaced or upgraded by the user. The laptop is 18mm thick and weighs around 4.5 pounds. Connectivity includes USB-C, USB-A, HDMI, a 3.5mm audio jack and a full-size SD card reader. The Surface Laptop Ultra introduces Magnetic Connect, a new magnetic port that supports power, data and video while preserving magnetic attachment convenience. It will be offered in Platinum and Nightfall finishes.

Microsoft is positioning the laptop heavily around local AI workloads. The hardware is designed to run demanding AI models and agentic workloads directly on the device, reducing reliance on cloud processing. That emphasis places the Surface Laptop Ultra toward professional users rather than everyday laptop buyers.

Microsoft has opened pre-orders in the US, with shipments scheduled to begin October 16. The base configuration with 24GB of RAM and 512GB of storage costs $2,599.99. The 24GB plus 1TB model is $2,999.99, while the 32GB plus 1TB configuration is $3,299.99. The top model, with 128GB of unified memory and 1TB of storage, is priced at $5,899.99.

Shipments are scheduled to begin in the US on October 16.
