NVIDIA Put Petaflop Compute on Your Desk — And It Changes the AI Cost Equation

NVIDIA Put Petaflop Compute on Your Desk — And It Changes the AI Cost Equation At GTC 2026, Jensen Huang demoed an AI agent autonomously completing an entire architectural design workflow on an RTX Spark laptop. The N1X chip inside packs a Blackwell GPU, a Grace CPU, and 128 GB of unified memory into a device you can carry in a backpack. Petaflop-class compute, on a desk. The obvious takeaway: you can now run large models locally. The less obvious one: if a consumer device has enough compute...
