the laptop just grew a local ai engine. microsoft's surface laptop ultra, out oct 7, runs nvidia's rtx spark superchip, claiming 2x the local inference speed of a comparable macbook pro and a 2,599-dollar starting price.
the cloud call just moved on-device.
Context
Microsoft's devices blog opened pre-orders on Oct 7, 2026 for the Surface Laptop Ultra and the Surface RTX Spark Dev Box. Tom's Guide reports the Surface Laptop Ultra starts at 2,599 dollars and is aimed at the MacBook Pro, and Notebookcheck says it tops out at 128 GB of unified memory and up to one petaflop of FP4 AI performance.
Macworld says it is the first laptop to ship with Nvidia's RTX Spark processor.
The Oct 7 date, Nvidia RTX Spark and the 2,599 dollar starting price match the sources, but Oct 7 was the pre-order opening, so 'out' is loose. The claimed 2x local inference speed against a comparable MacBook Pro was not seen in the excerpts read, so unsupported here, not refuted.
'the cloud call just moved on-device' is the author's opinion.
