NVIDIA and Microsoft on Saturday unveiled a new generation of Windows computers designed to run artificial intelligence agents directly on users’ devices, marking what the companies described as a major shift in personal computing.

The new platform, called RTX Spark, is built around a custom NVIDIA superchip that delivers up to one petaflop of AI computing performance and as much as 128 gigabytes of unified memory, NVIDIA said in a news release.

The companies say the technology is designed to support personal AI assistants capable of completing tasks, reasoning across applications, and handling creative workloads without relying entirely on cloud services.

About the RTX Spark Chip

NVIDIA CEO Jensen Huang said the industry is moving beyond traditional software applications toward AI-driven computing. “The PC is being reinvented,” Huang said during the announcement.

The RTX Spark chip combines an NVIDIA Blackwell graphics processor with a 20-core Grace CPU connected through NVIDIA’s NVLink technology. MediaTek collaborated on the CPU design, contributing to power efficiency and connectivity features.

A key part of the partnership focuses on security. Microsoft and NVIDIA said they are developing new Windows security features and NVIDIA’s OpenShell runtime to help users control what AI agents can access and how personal information is handled. The companies say the system will allow AI agents to run locally while maintaining privacy and user oversight.

Adobe is redesigning parts of Photoshop and Premiere to take advantage of the new hardware. The company expecting up to twice the AI and graphics performance in some workflows.

RTX Spark-powered laptops and compact desktop PCs are coming from several manufacturers. They include ASUS, Dell, HP, Lenovo, Microsoft Surface and MSI. The new models are expected to launch this fall.
