NVIDIA announces RTX Spark, a Windows on Arm superchip for laptops and compact PCs

Ahead of Computex 2026, NVIDIA teased that a "new era of PC" was coming, and with the formal announcement of RTX Spark, the company's first superchip built for Windows PCs and laptops, it's certainly a game-changer. The RTX Spark is NVIDIA's long-rumored Windows on Arm CPU and GPU combo, featuring a high-performance Arm-based 20-core Grace CPU paired with an NVIDIA Blackwell RTX GPU with up to 6,144 CUDA Cores and fifth-generation Tensor Cores.

NVIDIA collaborated with MediaTek to develop the chip, built on TSMC's 3nm process node, which the company says delivers "best-in-class power efficiency, performance, and connectivity." RTX Spark delivers NVIDIA's full AI and graphics technology stack to ultra-thin laptops and portable mini PCs, including all of the GeForce RTX technologies that Windows users have had access to for years, including powerful ray-tracing and the latest DLSS 4.5 neural rendering technologies.

RTX Spark laptops are coming from companies like ASUS, Dell, HP, Lenovo, MSI, and even Microsoft - with a special Microsoft Surface Ultra on the way. With powerful performance, these RTX Spark laptops can render 90GB 3D scenes with OptiX and DLSS, edit 12K 4:2:2 video with the NVIDIA Blackwell decoder, and run 120-billion-parameter large language models with 1-million-token context. And, yes, as Windows on Arm devices, you're also looking at impressive gaming performance for an integrated GPU.

Although we don't have benchmarks for the RTX Spark, which are coming later as we get closer to the Fall 2026 launch, NVIDIA notes that these new laptops will have no problem running the latest AAA games at 1440p at over 100 FPS with ray tracing, DLSS 4.5, and NVIDIA Reflex. And when it comes to Windows on Arm, NVIDIA notes that it has been working with "100 Windows software providers" across games and applications to ensure full compatibility. The list includes Adobe, Blender, CompyUI, Riot Games, XBOX, NetEase, and more.

"The PC is being reinvented," said Jensen Huang, founder and CEO of NVIDIA. "For forty years, you launched apps. Click. Type. With RTX Spark and Microsoft Windows, you ask - and the PC does the work. RTX Spark brings everything NVIDIA has built - CUDA, RTX, our AI platform - into a single superchip. Local agents. Frontier models. Creative workflows. RTX games. All on a laptop. This is the new PC. The personal AI computer."
