The Surface Laptop Ultra is the first consumer laptop on NVIDIA's RTX Spark superchip — a Grace CPU and Blackwell RTX GPU sharing up to 128 GB of unified memory, running 120B-parameter models locally. It starts at $2,599 and ships October 16. The chip topology, not the spec sheet, is the real story.

Apple shipped two chips on the same day from two different generations. The M5 Ultra has the same 80 GPU cores and the same 512GB memory ceiling as the M3 Ultra it replaces — yet 4.5x the AI compute. Here is what that gap tells you about where local AI is really headed.
