Investing.com -- Nvidia unveiled a new chip designed to bring AI capabilities directly into personal computers (PCs) on Monday, sending semiconductor and technology stocks moving in opposite directions.

Chief Executive Jensen Huang, speaking at the Computex conference in Taiwan, said the RTX Spark chip is central to Nvidia’s effort with Microsoft to "reinvent the PC" for the AI era, the product of three years of collaboration between the two companies.

Shares in the PC makers set to build laptops powered by Nvidia’s new chip jumped in premarket and overseas trading. Dell, Microsoft, HP, Lenovo, Asus and MSI all gained, with Asus leading the way with a 10% surge on the Taiwan Stock Exchange.

ARM Holdings (NASDAQ: ARM) also soared more than 16% in U.S. premarket trading.

On the flip side, shares in Qualcomm, Intel and Advanced Micro Devices, all of which compete in the PC chip market, fell about 7.2%, 5.4%, and 4.5%, respectively.

The new chip is designed to run AI agents locally on devices rather than routing tasks through cloud servers, a shift industry experts said could fundamentally change how consumers interact with artificial intelligence.

The RTX Spark is "a new superchip... for the era of personal AI agents - offering a new class of computer that moves from tool to teammate," Nvidia said on its website.

The chip was developed with help from Taiwan’s MediaTek and will be built into a new line of Windows PCs from Lenovo, HP, Dell, Microsoft Surface, Asus and MSI, with models available in autumn. Acer and Gigabyte are expected to follow.

The announcement puts Nvidia squarely in competition with AMD, Intel and Apple in a PC chip market dominated by a handful of players. Lenovo, HP, Dell and Apple together accounted for nearly three-quarters of global PC shipments in the first quarter of this year, according to research firm Gartner.
