The 128GB unified memory and 1TB SSD configuration of the Microsoft Surface Laptop Ultra is currently out of stock on the official US website. The device is priced at $5,899.99, while other lower-spec models remain available for purchase.

Industry reports suggest that the rapid depletion of stock may be linked to limited initial supply, although Microsoft has not released official sales figures to confirm this. The laptop's compatibility with the CUDA ecosystem is considered a key factor for its target audience.

AI developers and content creators favor the device because most AI frameworks, inference engines, and creative tools are optimized for CUDA. This allows users to run existing software directly without needing to seek alternative solutions.

While competitors like the AMD Ryzen AI Max 400 offer up to 192GB of unified memory, the established CUDA ecosystem remains a significant barrier for rival platforms. Microsoft has not yet announced a restock date for the 128GB model.
