NVIDIA and Microsoft Launch RTX Spark PC Chip for On-Device AI Agents
NVIDIA unveiled RTX Spark, a superchip designed to run AI agents locally on Windows PCs without cloud connectivity. The chip combines an NVIDIA Blackwell GPU with 6,144 CUDA cores and a 20-core NVIDIA Grace CPU, delivering 1 petaflop of AI performance and supporting up to 128GB of unified memory.
The announcement signals a shift in how personal computers handle AI workloads. Instead of sending queries to cloud services, users can run 120-billion-parameter language models directly on their laptops with context windows up to 1 million tokens.
Security and Agent Management Built In
NVIDIA and Microsoft are collaborating on new Windows security features specifically for running agents on personal devices. The partnership includes NVIDIA OpenShell, a runtime that lets users define what agents can and cannot do, route queries based on privacy policies, and mask personal information before sending data to cloud services.
Agent developers including Nous Research (Hermes Agent) and OpenClaw are adopting these security layers for their Windows applications. The foundation addresses a barrier to agent adoption: users have been reluctant to run agents on primary work devices without clear privacy controls.
Creative Work and Gaming Performance
Adobe is rearchitecting Photoshop and Premiere from the ground up for RTX Spark. The company says the optimizations will deliver up to 2x faster AI and graphics performance for tasks like generative fill, video editing, and color correction.
RTX Spark can handle demanding creative workflows: rendering 90GB 3D scenes, editing 12K video at 4:2:2 chroma, and generating 4K AI video. For gaming, the chip runs AAA titles at 1440p resolution and over 100 frames per second with ray tracing enabled.
NVIDIA will release DLSS 4.5 Ray Reconstruction with a second-generation transformer model for Blender and game titles. RTX Video with 4x Frame Generation is coming to ComfyUI.
Hardware Lineup Ships This Fall
ASUS, Dell, HP, Lenovo, Microsoft Surface, and MSI are building RTX Spark systems. Acer and GIGABYTE will follow. Laptops will measure as thin as 14 millimeters and weigh as little as three pounds, with 14- to 16-inch color-accurate OLED displays.
Microsoft is releasing Surface Laptop Ultra, positioning it for creators, developers, and engineers. Dell's XPS 16 Creator Edition and HP's OmniBook line are also in development.
Small desktop PCs built for agents and creative work are also planned. NVIDIA is separately offering DGX Station for Windows, which scales Blackwell architecture to enterprise developers running agents at their desk.
Developer and Creator Support
Over 100 software providers are adopting RTX Spark, including Adobe, Blackmagic Design, Blender, CapCut, ComfyUI, and OTOY. Game studios such as KRAFTON, NetEase, Remedy Entertainment, Riot Games, and Xbox are building for the platform.
Yannik Marek, cofounder of ComfyUI, said the unified memory and processing power make RTX Spark "one of the best-performing laptops to run diffusion models." Georgi Gerganov, founder of llama.cpp, noted that optimized models running locally through his framework will "unleash the next wave of personal, private agents."
For AI for Product Development, RTX Spark represents a shift in where computation happens. Product teams building agent-based applications can now assume local processing capabilities rather than designing around cloud dependencies.
RTX Spark laptops and desktops will ship this fall. Microsoft and NVIDIA plan to discuss Windows agent capabilities for developers at Microsoft Build on June 2-3.
