Nvidia announces RTX Spark as ‘the most efficient PC chip ever built’
Nvidia announced the RTX Spark, an Arm-based chip family targeting laptops and mini-PCs, claiming it is the most efficient PC chip ever built. The chip, based on the GB10 architecture, will power devices from major laptop vendors, including Microsoft’s upcoming Surface model, with capabilities for AI-driven tasks and high-performance computing in ultra-thin designs.
Nvidia is expanding into consumer laptop chips with the RTX Spark, a family of Arm-based processors it calls the most efficient PC chip ever built. The flagship version features 20 CPU cores, 6,144 GPU cores, and up to 128GB of LPDDR5X memory, while lower-tier variants will offer reduced RAM options. The chip is an evolution of Nvidia’s GB10 architecture, originally used in its DGX Spark AI supercomputer, and will require Windows to run through an emulation layer for x86 software compatibility. The RTX Spark aims to deliver high-performance tasks like rendering a 90GB 3D scene, editing 12K video, or gaming at 100fps in 14mm-thin laptops without external power. Its unified memory architecture supports running 120-billion-parameter AI agents locally, aligning with Microsoft’s security advancements for Windows, which will showcase new containment features at its Build conference. Nvidia envisions a future where AI replaces traditional interfaces, allowing users to control devices via voice commands for tasks like adjusting streaming settings or automating design workflows. The company emphasizes privacy and efficiency, avoiding cloud-based AI token usage. Partners including Microsoft, Lenovo, and Dell will release RTX Spark-powered laptops this fall, with Microsoft’s Surface team calling its model the most powerful Surface device ever. The chip’s AI capabilities extend to developer tools, such as autonomous GitHub issue resolution, while maintaining performance parity with x86-based rivals. Nvidia’s push into Arm-based consumer chips positions it as a direct competitor to Qualcomm and Apple in the laptop market, leveraging its graphics and AI expertise to redefine personal computing.
