New NVIDIA Chip Lets Home Computers Run Smart Helpers Around the Clock

NVIDIA's new RTX Spark chip gives Windows computers powerful built-in AI, rated at 1 petaflop, enough to run smart assistants directly on the machine. Slim laptops from ASUS, Dell, HP and Lenovo run all day on battery, and a tiny low-power desktop can keep helpers working day and night. Microsoft says they arrive in October 2026.
