The race to dominate artificial intelligence has largely been fought inside massive data centers. Nvidia and Microsoft now want to bring that battle to personal computers, unveiling a new platform called RTX Spark that they say could transform Windows PCs into powerful AI machines capable of running advanced digital assistants locally.
For years, the tech industry has talked about AI powered computers.
The problem was that most PCs still relied heavily on cloud services to handle demanding AI tasks. Nvidia believes RTX Spark changes that equation by placing enormous computing power directly inside laptops and desktop computers.
At the heart of the platform is Nvidia’s new RTX Spark superchip, a processor that combines an Arm based CPU, Blackwell graphics technology and up to 128GB of unified memory. According to Nvidia, the system can deliver up to one petaflop of AI performance, allowing users to run large AI models directly on their devices rather than constantly relying on remote servers.
Nvidia says the traditional app based PC experience is giving way to a future where users simply ask their computers to complete tasks and AI agents handle much of the work automatically.
The announcement was one of the biggest moments at Computex 2026 and quickly became a major focus at Microsoft’s Build developer conference.
Nvidia CEO Jensen Huang described the technology as the beginning of a new era for personal computing, while Microsoft CEO Satya Nadella said the company’s goal remains delivering “unmetered intelligence” to homes and workplaces through Windows.
The partnership goes beyond hardware.
Microsoft and Nvidia are working together to build AI agents directly into the Windows experience. These agents are designed to perform tasks, manage workflows, assist with software and handle increasingly complex requests without requiring users to constantly switch between applications.
One of the first products built around the new technology is Microsoft’s Surface Laptop Ultra, which becomes the first Surface device powered by Nvidia’s RTX Spark chip. The company says the machine is aimed at developers, creators and professionals who need workstation-level performance in a portable device.
The technology is also attracting support across the broader PC industry.
Manufacturers including Dell, HP, Lenovo, Asus, MSI and Acer have announced plans to launch RTX Spark powered systems later this year, signaling confidence that demand for AI focused computers will continue growing.
For Nvidia, the move represents a significant expansion beyond the data center business that helped make it one of the world’s most valuable companies.
The company is now pushing directly into the personal computing market, challenging rivals such as Intel, AMD, Qualcomm and Apple in the race to define what the next generation of PCs will look like.
Whether consumers are ready for AI first computers remains an open question.
The industry has spent the last two years promoting “AI PCs,” but many buyers have yet to see a compelling reason to upgrade. Nvidia is betting that a laptop capable of running powerful AI models locally, editing complex media projects, supporting advanced gaming and acting as a personal AI assistant could finally provide that reason.
The first RTX Spark powered devices are expected to arrive in fall 2026.
If the technology performs as promised, it could mark one of the most significant shifts in personal computing since the smartphone era. If not, it will become another reminder that changing how people use computers is far more difficult than building faster hardware.
