Nvidia has been on the defensive against Intel and Advanced Micro Devices in recent months when it comes to artificial-intelligence processors. Now it's striking back at its peers' core market with an AI chip designed for personal computers.

Nvidia late on Sunday unveiled the RTX Spark, which it described as "the most efficient PC chip ever built," designed for personal devices to run AI agents -- programs that can act autonomously. It combines a central-processing unit alongside one of the company's Blackwell graphics-processing units.

The move is an effort to disrupt Intel and AMD's dominance of the PC chip market, with Nvidia using technology licensed from processor-design firm Arm Holding. It will also be competing with Qualcomm, which has made a push into the PC market with a range of AI chips.

Nvidia shares were up 1.9% in premarket trading Monday. Intel was down 1.7% and AMD was falling 1.7%. Qualcomm was dropping 3.5%.

Nvidia already sells the DGX Spark, a desktop workstation for AI engineers that costs $4,699, but the new chip will be aimed at consumer devices, although likely at the premium end of the market. Nvidia is working with PC manufacturers including Microsoft, Dell and HP. Eventually, there will be 30 laptop models and about 10 desktop models using the new chips, Nvidia said.

The announcement was made at the Computex conference, the annual event that acts as a showcase for Taiwan's technology industry.
