Nvidia N1X officially confirmed to arrive as the RTX Spark

Nvidia’s long-awaited Windows on ARM chip is finally here. It is made on an unspecified 3 nm node from TSMC. Formerly known as the N1X, which was likely its internal codename, the chip will launch as the RTX Spark. It won’t be the only one, with Nvidia stating other, lower-specced SKUs expected to surface later. Of course, this isn’t exactly new information. Multiple reports talked about the N1X and its sub-variants at length, with the most recent leak confirming at least two variants.

Officially, Nvidia has refused to divulge much in the way of specs. The RTX Spark will come with an unspecified GPU with 6,144 CUDA cores and a 20-core CPU tailor-made by MediaTek. Nvidia claims the GPU can comfortably run games at 1440p thanks to DLSS 4.5, Frame Generation, Reflex, and the laundry list of gaming features found on Blackwell GPUs. Ray reconstruction and RTX Video Frame Gen are also supported.

Creatives will be pleased to know that Adobe Photoshop and Premiere will run on the RTX Spark on day one. Other companies, such as Blackmagic Design, Blender, CapCut, ComfyUI and OTOY have also partnered up with Nvidia to bring their software stack to the platform. The company claims power users can render 90 GB 3D scenes with OptiX and DLSS and edit 12K 4:2:2 video with the NVIDIA Blackwell decoder. Nvidia confirmed the machine will run Windows at launch but didn’t confirm/deny Linux support.

The Nvidia RTX Spark supports up to 128 GB of LPDDR5X unified memory. With NVlink, its memory bandwidth peaks at 600 GB/s. Like everything else Nvidia has announced in the past year, the RTX Spark is touted as an AI powerhouse with 1 peraflops of FP4 performance. The company claims it can run 120 billion parameter models locally and even run ‘gaming agents’ that can, among other things, change your monitor’s refresh rate. 

Nvidia has not shown off any performance metrics of the RTX Spark, meaning we have to rely on leaked benchmarks to figure out how it fares against other Arm-based offerings from Apple and Qualcomm. E-sports gamers will be pleased to know that Nvidia is actively working with numerous anti-cheat software makers to get the RTX Spark ready for popular titles. For now, the list includes Fortnite, Valorant, League of Legends, and PUBG, with more titles coming soon.

Some of the laptops that will launch with the RTX Spark include the Asus ProArt P14, ProArt P15, Dell XPS 16, HP OmniBook X 14, HP OmniBook Ultra 16, Lenovo Yoga Pro 9n, Microsoft Surface Laptop Ultra and MSI Prestige N16 Flip AI. It will also power some mini-PCs, but Nvidia didn’t specify which ones. Machines powered by the RTX Spark are expected to hit shelves in Fall 2026.
