Microsoft and NVIDIA on May 31 announced a new category of Windows PCs powered by NVIDIA’s RTX Spark superchip, bringing AI processing directly onto personal computers.
The announcement was made during NVIDIA GTC Taipei and is positioned around running AI agents and large AI models locally on Windows devices.
The companies said RTX Spark integrates CPU, GPU and memory into a single architecture built for AI workloads, graphics processing and everyday computing.
“Builders and creators today are reimagining how things get done, and they need reimagined hardware, silicon and platform capabilities to support them,” said Microsoft in a statement. “They need PCs capable of running graphically intensive tasks efficiently, highly capable AI models, and a platform that simply and securely runs agents locally.”
According to the company, future Windows experiences powered by RTX Spark will be accessible through the Windows interface and taskbar.
NVIDIA’s RTX Spark superchip delivers up to one petaflop of AI performance. The platform combines NVIDIA’s Blackwell RTX architecture with Arm-based CPU cores and up to 128 GB of unified memory, enabling AI workloads to run directly on Windows devices.
NVIDIA partnered with MediaTek to develop the Arm-based CPU that powers RTX Spark.
NVIDIA is also bringing its OpenShell framework to Windows, built on new security and containment capabilities introduced by Microsoft. OpenShell is NVIDIA’s framework for connecting AI agents with applications and system tools.
The companies said AI agents such as Hermes Agent and OpenClaw will run on Windows using OpenShell, allowing users to perform tasks locally instead of relying on cloud services.
Microsoft said users will retain control over how AI agents operate on Windows, with tools that provide visibility into what data and system resources agents can access.
The first RTX Spark-powered Windows devices are expected to arrive this fall, including laptops and compact desktop PCs from Microsoft Surface, ASUS, Dell, HP, Lenovo and MSI.
The launch deepens NVIDIA’s push into the Windows PC market, where Intel, AMD and Qualcomm have traditionally supplied processors. Reuters reported in 2023 that NVIDIA was developing Arm-based chips for Windows devices, a move that is now materialising with RTX Spark.
