Microsoft Surface Laptop Ultra leaks with NVIDIA RTX Spark and 128GB unified memory

Technetbook reports that Microsoft’s Surface Laptop Ultra may be equipped with NVIDIA RTX Spark and up to 128GB of unified memory. If the leak is accurate, the device would target demanding local AI, creative, development, and other workloads that can benefit from a large shared CPU-and-GPU memory pool. The report describes leaked product information rather than a confirmed Microsoft specification or independent performance result.

The RTX Spark platform combines an Arm-based NVIDIA Grace CPU with Blackwell graphics, unified memory, and NVIDIA’s CUDA and RTX software stack. A 128GB configuration could be useful for memory-heavy applications, but capacity alone does not establish speed, battery life, thermals, acoustics, software compatibility, or value. The final processor and GPU configuration, power limits, cooling, Windows on Arm support, storage, and application compatibility will matter once Microsoft publishes complete specifications.

For Canadian buyers, the report does not confirm Canadian pricing, retailer stock, warranty coverage, or local shipping. Prospective buyers should treat the Surface Laptop Ultra as unconfirmed, wait for Microsoft’s official announcement and Canadian listings, and compare independent tests with RTX Spark laptops, x86 workstations, and Apple silicon Macs before making a purchase decision.
