Overview
- Microsoft and Nvidia unveiled the Surface Laptop Ultra on Oct. 7 in San Francisco, presenting two RTX Spark configurations that pair an Arm-based Grace CPU with a Blackwell GPU and up to 128 GB of unified LPDDR5X memory.
- Microsoft opened preorders at a $2,599 entry price and set shipments to begin around Oct. 16 while noting higher-memory and top-tier SKUs will cost substantially more.
- Windows now includes specific AI features to run local models: GitHub Copilot can route tasks to on-device models, a ‘Hybrid Intelligence’ flow lets local models perform permitted file and app actions, and Defender and scheduler changes aim to contain and manage agent activity.
- Key unresolved questions remain about real-world behavior, with early hands-on reports noting rough drivers, and ongoing concerns about battery life, thermals, sustained performance, and exact pricing for 64 GB–128 GB configurations.
- Multiple OEMs are planning RTX Spark laptops and a desktop Dev Box, a move that could shift some cloud workloads to expensive local machines for developers and professionals while limiting broader adoption because high unified-memory costs raise device prices.
