Nvidia unveils RTX Spark Superchip for laptops and desktop PCs at Computex 2026 – new platform promises to turn Windows into an agentic AI OS with Arm CPU, Blackwell GPU, and 128GB unified memory
Nvidia is transforming Windows into an agentic AI platform at 2026. During his keynote, CEO Jensen Huang revealed RTX Spark: a Windows on Arm platform for laptops powered by the company’s RTX Spark Superchip. The company boldly claims that this platform is “the most efficient ever built,” and it’s throwing its full weight into building a first-class Windows on Arm experience for what it envisions as the next frontier of personal computing.
Nvidia says AI agents are already shaping a new mode of interaction with PCs. Instead of relying on the same mouse and keyboard inputs that have defined personal computing for 40 years, the company sees AI agents as a new interface that allows users to command their systems and find information with natural language.
And once those agents have their marching orders, they’ll need to set goals, call tools, evaluate the quality of their work, and refine it, potentially using local and cloud AI models to achieve those ends. Agents might also continue working on long-running tasks even when the user is away from their system or overnight. That all requires powerful, efficient hardware and lots of local memory.
To power all this AI reasoning in the new era of computing it envisions, Nvidia is unleashing the RTX Spark Superchip, a Windows on Arm platform more powerful and capable any other on the market.
At full strength, this chip offers up to 20 Arm CPU cores, a Blackwell GPU with 6144 CUDA cores, 128GB of LPDDR5X RAM, and up to 300 GB/s of memory bandwidth. That powerful CPU and GPU, connected over NVLink C2C, and the large memory pool give AI agents and 120-billion-parameter models plenty of power and space for long-running tasks with context lengths stretching to a million tokens, according to Nvidia.
RTX Spark will power high-end laptops from partners including Dell, HP, Lenovo, Microsoft, Asus, and MSI. Nvidia says it’s worked with those partners to create “the most extraordinary laptops [they’ve] ever built,” with tandem OLED G-Sync displays, “all-day” battery life, premium aluminum chassis with large glass touchpads.
Nvidia says that the incredible efficiency of the RTX Spark platform “transforms what a high-performance laptop looks like,” so buyers in the promised agentic AI age will no longer need to choose between high performance or thin chassis with long battery life. RTX Spark PCs will also deliver similar performance whether plugged in or unplugged, as we’ve come to expect from other Windows on Arm and Apple Silicon-powered systems.
RTX Spark will also bring this agentic Windows on Arm experience to compact, powerful desktops in the vein of the DGX Spark. In total, Nvidia expects over 30 laptops and “10 or so” desktops to lead the charge when the platform launches.
In addition to its agentic AI chops, Nvidia positions the RTX Spark Superchip as a creative and gaming powerhouse. The company promises the platform is good for “100 FPS 1440p gaming,” potentially enabled by DLSS 4.5 upscaling and Multi Frame Generation. And its large memory pool means creators can work with massive 3D projects and ultra-high resolution video files like 12K 4:2:2 content without running out of resources.
To further the RTX Spark platform’s creative chops, Nvidia says it’s working with Adobe to rebuild the core of Photoshop, transforming it into a 100% GPU-accelerated application for RTX Spark. Those updates will enable new generative workflows, high-dynamic-range editing, and more natural brushing for artists.
And Premiere is also getting a core overhaul that’s claimed to enable faster and more sophisticated AI workflows, editing, color, and effects. Adobe will also expose Model Context Protocol controls for AI agents to harness its products.
In partnership with Microsoft, Nvidia is also helping to transform Windows into an agentic platform with its OpenShell framework and a “new set of security primitives” that form a set of guardrails, ensuring that local agents and models only have access to the tools and data the user grants them access to. Nvidia says Microsoft will reveal more details of this agentic AI transformation at its upcoming Build conference.
RTX Spark systems will begin arriving in the fall of 2026, and we can’t wait to dig into them to see whether Nvidia’s backing will truly transform the Windows on Arm experience for the agentic AI era – or just make for a really great PC platform. Stay tuned.
