Nvidia unveils Arm-based AI PC chips, lifting Arm stock and pressuring Intel

Shares of Arm Holdings surged, while Intel fell after Nvidia and Microsoft unveiled a new AI-focused chip for Windows PCs, a move that could reshape the personal-computer market by pushing more artificial intelligence processing onto laptops and desktops. Bloomberg reported that the new chip is designed to power AI features in Windows machines later this year, and that Nvidia is using technology licensed from Arm for the effort.

According to Bloomberg and Fast Company, Nvidia’s new PC push centers on a chip called RTX Spark and a related N1X processor, which the company is positioning as an AI superchip for personal devices. Apple Podcasts’ “Stock Movers” episode said Nvidia described RTX Spark as “the most efficient PC chip ever built,” and reported that the chip is intended to help devices run AI agents more effectively.

The announcement is significant because it puts Nvidia directly against Intel and AMD, two companies that have long dominated PC processors. Bloomberg said the new chip is meant to loosen Intel’s grip on the PC market and modernize computers for the AI era, while the podcast noted that Nvidia plans to debut the chip in laptops and desktops from major PC makers including Dell and Lenovo starting this fall.

Investors responded quickly. Arm’s shares climbed on the news because Nvidia’s PC strategy depends on Arm-based technology, while Intel shares slid as the market weighed the threat to its position in PCs. Nvidia itself also rose, reflecting confidence that the company can extend its lead in AI chips beyond data centers and into consumer computers.

The move comes as Nvidia is broadening its reach across the AI ecosystem. Bloomberg separately reported that Nvidia chief executive Jensen Huang has been highlighting partnerships in South Korea and that the company is also working with firms such as ABB Robotics on so-called physical AI, showing how Nvidia is trying to expand from chips into broader AI-enabled systems.

The broader backdrop is a market still heavily focused on AI infrastructure and chip supply. Bloomberg also reported that Hewlett Packard Enterprise has been benefiting from strong demand for AI servers and networking gear, underscoring how the AI boom is lifting some hardware makers while threatening others. At the same time, Nvidia remains exposed to geopolitical risk: Bloomberg reported that Chinese universities with ties to the country’s military and defense industry are seeking access to Nvidia’s H200 chips, highlighting continuing scrutiny around advanced chip sales to China.

For PC makers and software developers, the new chip could accelerate a shift toward computers built specifically for AI assistants and on-device AI features. For Intel, it is another warning sign that the next phase of the PC market may be defined less by traditional speed improvements and more by which company can best support AI functions in everyday laptops and desktops.
