Nvidia Corp. introduced the RTX Spark system-on-chip for Windows laptops and compact desktops. The chip, based on the Blackwell architecture, includes 6,144 CUDA cores and specialized Tensor Cores for AI tasks. It combines a 20-core Grace CPU, developed with MediaTek Inc., and 128 GB of unified memory via NVLink-C2C interconnect, delivering up to 1 petaflop of FP4 performance.
The RTX Spark enables on-device LLMs up to 120 billion parameters with a 1 million context window. It supports AI agents like OpenClaw, with Microsoft adding identity, containment, and security features for agent controls. Nvidia will provide OpenShell for sandboxed agent execution.
Nvidia CEO Jensen Huang stated, "Microsoft and Nvidia are going to reinvent the PC. This is the first completely reengineered, reinvented line of PCs that has happened in 40 years."
Beyond AI, the chip enhances gaming with DLSS 4.5 Ray Reconstruction and accelerates creative apps like Adobe Photoshop up to twice as fast. Partners include Microsoft with the Surface Laptop Ultra, featuring a 15-inch display and 24-hour battery life.
