RTX Spark is Nvidia’s ‘superchip' for Windows PCs with 1 petaflop of AI, 128GB RAM, and RTX 5070-tier graphics

For thirty years, Nvidia made the GPU inside your PC. Now it makes the chip inside it too. At GTC Taipei and Computex 2026, Jensen Huang unveiled RTX Spark—a full system-on-a-chip with a 20-core Arm CPU, a Blackwell GPU with 6,144 CUDA cores, and up to 128GB of unified memory. It runs on the same GB10 silicon as the $4,699 DGX Spark desktop supercomputer. Only now it fits inside a 14mm-thin Windows laptop (and mini PCs too).

The spec are: 1 petaflop of FP4 AI compute, 300GB/s memory bandwidth, and enough room to run 120-billion-parameter models locally with up to 1 million tokens of context. CPU and GPU talk to each other over NVLink-C2C, scaling from low single-digit watts up to 80W. Huang’s pitch on stage: “For forty years, you launched apps. Click. Type. With RTX Spark, you ask—and the PC does the work.”

Nvidia says RTX Spark runs every Windows app ever made, and pushes AAA games at 1440p on battery

The performance claims don’t let up. RTX Spark is supposed to handle AAA games at 1440p and over 100fps, 12K 4:2:2 video editing, and 3D scene renders exceeding 90GB—all on battery. Adobe isn’t just tweaking settings either. It’s rebuilding Photoshop and Premiere’s core rendering engines from scratch for this chip, targeting up to 2x faster performance across editing, color, and effects.

Gaming compatibility gets a hard look too. League of Legends, Valorant, and PUBG are confirmed for Windows on Arm, with native anti-cheat from Epic’s Easy Anti-Cheat and BattlEye now on board. Huang went further during the keynote, claiming RTX Spark will run “every single application that Windows has ever run—meticulously optimized so that this computer literally runs everything the world has ever created.” Windows on Arm’s Prism emulation already handles most x86 apps without a fuss, but edge cases have always been the sticking point. Whether Nvidia has actually plugged those holes is something only shipping hardware will answer.

On the AI agent side, Nvidia is shipping a new OpenShell runtime built on new Windows security primitives. It lets users set hard limits on what local agents can access—which files, which apps, what data ever leaves the device. OpenClaw and Hermes Agent are already integrating it, with Microsoft set to go deeper on the Windows agent platform at Build, starting June 2.

Microsoft, Dell, Asus, HP, Lenovo, and MSI all have RTX Spark laptops coming

Eight devices are confirmed for this fall: Microsoft Surface Laptop Ultra, Dell XPS 16 Creator Edition, Asus ProArt P14 and P16, HP OmniBook X14 and Ultra 16, Lenovo Yoga Pro 9N, MSI Prestige N16 Flip AI+. Microsoft is calling the Surface Laptop Ultra the most powerful Surface device it has ever built.

Nvidia says 30-plus laptops and around 10 desktops are in the pipeline across Acer, GIGABYTE, and others—so the first eight are just the opening move. No pricing has been confirmed yet, though Nvidia has been clear that the launch lineup is squarely aimed at the premium end of the market.
