Microsoft opened pre-orders this week for the Surface Laptop Ultra, a notebook built around NVIDIA's RTX Spark superchip, starting at $2,599. Availability begins on October 16. In the same announcement, the company put the Surface RTX Spark Dev Box on sale for $5,999, exclusive to Microsoft.com in the United States, with shipping expected in November.
The post went up on October 7 on Microsoft's official devices blog, signed by Brett Ostrum, corporate vice president of Surface. The package is part of the company's bet on hybrid intelligence: some AI work stays on the PC, some goes to the cloud. Jensen Huang of NVIDIA and Satya Nadella took part in the San Francisco event.
What the hardware promises
According to Microsoft, the Surface Laptop Ultra pairs a Blackwell RTX GPU with up to 6,144 cores, a Grace CPU with up to 20 cores and up to 128 GB of unified memory. The company says the system can run AI models above 120 billion parameters on device, with up to 1 petaflop of AI performance. Its own footnote treats the petaflop as theoretical FP4 performance with sparsity, and notes that 128 GB is shared between CPU and GPU: the slice the graphics processor can address is less than the total.
The display is a 15-inch PixelSense Ultra panel, described by Microsoft as the brightest and sharpest it has put on a Surface Laptop. The notebook is also meant to drive up to three 4K displays. The desktop Dev Box repeats the superchip recipe, with the same unified-memory ceiling and the same pitch of models above 120 billion parameters, aimed at a fixed development station.
Why it matters
RTX Spark is not limited to Microsoft. NVIDIA said notebooks with the chip are open for pre-order now and arrive on October 16, with compact desktops in November. Partners include Acer, ASUS, Dell, HP, Lenovo, MSI and Gigabyte, plus Microsoft itself. The pitch is a Windows PC that can run AI agents on device, with CUDA, and still handle creation and games.
In practice, price sets the audience. $2,599 is the entry point for the Surface Laptop Ultra, not the ceiling: configurations with more memory go well above that. The Dev Box, at $5,999, competes with compact workstations, not ordinary notebooks. Microsoft also talks about execution containers for agents and controls that separate agent activity from user activity, but some of those Windows features are still described as upcoming.
