NVIDIA GTC Taipei --NVIDIA today unveiled NVIDIA RTX Spark™, a new superchip that reinvents Windows PCs for the era of personal AI agents — offering a new class of computer that moves from tool to teammate.

Designed for AI, creating and gaming, RTX Spark brings together 30 years of NVIDIA innovation — including NVIDIA CUDA®, NVIDIA RTX™, DLSS, FP4, NVIDIA TensorRT™, NVIDIA OptiX™, Reflex and G-SYNC® — to slim Windows laptops with all-day battery life and small, ultraefficient desktop PCs.

"The PC is being reinvented," said Jensen Huang, founder and CEO of NVIDIA. "For forty years, you launched apps. Click. Type. With RTX Spark and Microsoft Windows, you ask — and the PC does the work. RTX Spark brings everything NVIDIA has built — CUDA, RTX, our AI platform — into a single superchip. Local agents. Frontier models. Creative workflows. RTX games. All on a laptop. This is the new PC. The personal AI computer."

The RTX Spark superchip features an NVIDIA Blackwell RTX GPU with 6,144 CUDA cores and fifth-generation Tensor Cores with FP4 precision, connected via the NVIDIA NVLink®-C2C chip-to-chip interconnect to a high-performance, 20-core NVIDIA Grace™ CPU.

MediaTek, a market leader in Arm-based system-on-a-chip designs, collaborated with NVIDIA on the custom CPU design, contributing to its best-in-class power efficiency, performance and connectivity.

Purpose-Built for Personal Agents

AI agents have reached an inflection point, with open source projects such as OpenClaw and Hermes Agent achieving record-breaking numbers on developer networks like GitHub and OpenRouter. Yet broad adoption has been limited by the inability to run agents securely and privately on users' primary PCs.

NVIDIA and Microsoft are partnering to address this challenge by delivering a robust, secure Windows platform for on-device agents.

The collaboration begins with a strong foundation — new Windows security primitives and the NVIDIA OpenShell™ runtime — to ensure agents run safely and under full user control.

The new Windows primitives deliver identity, containment, policy and end-to-end security capabilities to build and run agents natively. NVIDIA OpenShell provides additional policy capabilities for the user to define what agents can and cannot do, the ability to intelligently route queries to local models based on the user's privacy policies, and the ability to disguise personal information in queries sent to cloud models.

This robust security and privacy layer is being adopted by leading agent developers such as Hermes Agent and OpenClaw in their new Windows apps. These new apps will make it easy and secure for users to access powerful on-device agents that can execute tasks in Windows applications, reason through cross-app workflows, generate images and video, code plug-ins and apps, and semantically search local files.

"We are strong supporters of deploying agents like OpenClaw securely into the Windows ecosystem," said Vincent Koc, chief architect at the OpenClaw Foundation. "Running solutions like OpenShell and the Microsoft security primitives on RTX Spark will enable users to leverage a fully integrated stack for private, personal agents running on device."

Powering agents on local devices requires both robust security and performant hardware. RTX Spark features up to 1 petaflop of AI compute and 128GB of unified memory to meet the processing demands of on-device agents.

"At Nous, we expect tasks to increasingly run on device as personal agents like our Hermes Agent become more capable and ubiquitous," said Dillon Rolnick, CEO of Nous Research. "RTX Spark and NVIDIA OpenShell give Hermes users a powerful and secure environment for agents to run and work alongside you. You realize you're buying a full-fledged assistant, not a typical laptop."

From this foundation, NVIDIA and Microsoft's collaboration will expand to new RTX Spark-powered Windows agent experiences accessible from the Windows taskbar user interface.

"Our goal is to deliver unmetered intelligence to every home and every desk with Windows," said Satya Nadella, chairman and CEO of Microsoft. "RTX Spark marks a real breakthrough towards that vision."
