Surface Laptop Ultra: 128GB RAM, RTX Spark Chip [2026]

tech-insider.org reports that Microsoft's Surface Laptop Ultra is expected to combine the RTX Spark platform with up to 128GB of memory. The headline positions the device as a high-capacity Windows laptop for local AI, creative work, development, and other workloads that can benefit from a large shared CPU-and-GPU memory pool. The report describes an expected product configuration, not an independent performance result or a confirmed retail specification.

RTX Spark systems pair an Arm-based NVIDIA Grace CPU with Blackwell graphics, unified memory, and NVIDIA's CUDA and RTX software stack. In practice, the Surface Laptop Ultra's usefulness will depend on the final memory tier, power limits, cooling, battery life, Windows on Arm compatibility, drivers, application support, and sustained performance. A 128GB headline alone does not establish how much memory is available to a particular workload or whether the laptop will outperform x86 systems and Apple silicon Macs.

For Canadian buyers, the report does not confirm Canadian pricing, retailer stock, warranty coverage, or local shipping. Prospective buyers should wait for Microsoft to publish final configurations and Canadian listings, then look for independent testing of thermals, acoustics, local AI, creative software, gaming, and total ownership cost before treating the Surface Laptop Ultra as a purchase recommendation.
