NVIDIA has finally put a name and a product shape around its long-rumored Windows-on-Arm play: RTX Spark, a new laptop processor unveiled at Computex Taipei 2026. It combines a 20-core Grace CPU, a Blackwell RTX GPU with 6,144 CUDA cores, an NPU, and up to 128GB of unified LPDDR5X memory in a single TSMC 3nm package, with NVIDIA claiming 1 petaFLOP of AI performance.
That puts RTX Spark squarely in Apple silicon territory and sends a very direct message to Qualcomm’s Snapdragon X lineup, which has had a relatively easy run defining the Windows on Arm category. NVIDIA is also doing the sensible thing: it is not shipping hardware alone, but bringing the software stack it already knows how to monetize, from CUDA and TensorRT to DLSS 4.5, Reflex, G-SYNC, and RTX ray tracing.
RTX Spark specs and AI claims
The headline numbers are aggressive. NVIDIA says RTX Spark can run 120 billion-parameter AI models locally, handle 12K 4:2:2 video editing, render 3D scenes larger than 90GB, and push AAA games at 1440p above 100 frames per second. The gaming claim leans on DLSS 4.5 and Frame Generation, which means the pitch is as much about NVIDIA’s software tricks as the silicon itself.

Adobe and other software partners are already lined up
Adobe is going further than a compatibility checkbox. The company says it is overhauling Photoshop and Premiere for RTX Spark, with promises of up to 2x gains in AI and graphics work. Blackmagic Design, Blender, CapCut, ComfyUI, and OTOY are also on board, which is exactly the sort of ecosystem support a new Arm PC chip needs if it wants to avoid becoming another impressive demo with nowhere to go.
That broader support matters because hardware alone rarely wins this fight. Apple’s M-series chips made the same lesson painfully clear for the rest of the industry: if the software story is thin, even fast silicon ends up feeling like a science project.
RTX Spark laptops will be thin and arrive this fall
NVIDIA says the first RTX Spark laptops will be 14mm thick, weigh 3 pounds, and come in 14-inch and 16-inch versions with OLED displays and precision-machined aluminum chassis. ASUS, Dell, HP, Lenovo, Microsoft Surface, and MSI are all named as launch partners, and the first systems are due this fall.
The missing piece is the one buyers will care about most: benchmark numbers. NVIDIA has shown the spec sheet and the ecosystem plan, but not the hard evidence that will tell us how RTX Spark stacks up against Qualcomm, Apple, or even high-end x86 laptops. If leaks start appearing before fall, that comparison will get much more interesting very quickly.
