Nvidia unveils AI superchip RTX Spark to power AI-first personal computers

TAIPEI:: The personal computer is getting an AI-powered makeover. At its GTC Taipei event, NVIDIA unveiled the new NVIDIA RTX Spark superchip, a platform designed to transform Windows PCs from productivity tools into AI-powered digital teammates capable of running advanced personal agents directly on the device.

The company claims RTX Spark delivers up to one petaflop of AI performance while packing up to 128GB of unified memory, enabling users to run large AI models locally, create complex content and play high-end games on thin-and-light laptops and compact desktop PCs.

Describing the shift as a major evolution for computing, NVIDIA founder and CEO, Jensen Huang, said the traditional model of launching applications is being replaced by AI-driven interactions where users simply ask a computer to complete tasks.

At the heart of RTX Spark is an NVIDIA Blackwell RTX GPU featuring 6,144 CUDA cores and fifth-generation Tensor Cores, paired with a 20-core NVIDIA Grace CPU. The CPU was developed in collaboration with MediaTek, with a focus on power efficiency, connectivity and performance.

A major pillar of the announcement is NVIDIA’s expanded partnership with Microsoft to create what the companies describe as the first Windows environment purpose-built for personal AI agents.

The collaboration introduces new Windows security primitives alongside NVIDIA OpenShell, a runtime designed to give users greater control over how AI agents operate on their devices. OpenShell allows users to define permissions, route queries between local and cloud-based AI models, and protect sensitive personal information.

The system is aimed at enabling agents that can work across applications, search local files, generate content, write code and automate workflows while maintaining privacy and security.

Commenting on the partnership, Microsoft chairman and CEO Satya Nadella said the goal is to bring “unmetered intelligence” to every desk and household through Windows-powered AI experiences.

Beyond AI agents, RTX Spark is also targeting creators and gamers. NVIDIA says the platform can render 90GB-plus 3D scenes, edit 12K 4:2:2 video, generate 4K AI video content and run 120-billion-parameter large language models with context windows of up to one million tokens.

Gaming remains a major focus. RTX Spark systems will support ray tracing, DLSS, Reflex and G-SYNC technologies, allowing users to play AAA titles at 1440p resolution and more than 100 frames per second. NVIDIA also announced new enhancements including DLSS 4.5 Ray Reconstruction and RTX Video with 4x Frame Generation.

The company has secured support from more than 100 software developers and gaming studios. Partners include Adobe, Blackmagic Design, ComfyUI, OTOY, Xbox, NetEase and Remedy Entertainment.

Among the most notable collaborations is NVIDIA’s expanded partnership with Adobe. The software maker is reengineering Photoshop and Premiere Pro for RTX Spark, promising up to twice the AI and graphics performance. Adobe’s Firefly-powered Generative Fill and Generative Extend tools are expected to benefit significantly, while Photoshop, Premiere and Substance 3D applications will gain deeper optimisation for the new architecture.

The hardware ecosystem around RTX Spark is also substantial. Devices powered by the platform will launch this autumn from leading manufacturers including ASUS, Dell Technologies, HP Inc., Lenovo, MSI and Microsoft’s Surface division, with additional systems from Acer and GIGABYTE arriving later.

The laptops are expected to measure as little as 14 millimetres thick and weigh around three pounds, while featuring OLED displays, all-day battery life and premium aluminium designs. Compact desktop systems will also be available for creators, developers and gamers seeking more powerful local AI capabilities.

With AI agents moving rapidly from concept to reality, RTX Spark signals NVIDIA’s ambition to place advanced AI computing directly into consumers’ hands. If the company delivers on its promises, the next generation of Windows PCs may be remembered less for the apps they run and more for the assistants they become.
