Nvidia opened Computex 2026 in Taipei with the RTX Spark, a 1-petaflop superchip that combines an Arm-based CPU, a Blackwell RTX GPU, and a full-stack AI software platform into a single package for Windows laptops and desktops. Microsoft, Dell, HP, Lenovo, ASUS, and MSI will ship RTX Spark systems this fall.
A superchip for a supercomputer on your desk
The RTX Spark is not a conventional processor. It integrates a 20-core Nvidia Grace CPU (co-designed with MediaTek) with a Blackwell RTX GPU featuring 6,144 CUDA cores and fifth-generation Tensor Cores with FP4 precision, connected via NVLink-C2C chip-to-chip interconnect. The system supports up to 128 GB (128 gigabytes) of unified memory — enough to run a 120-billion-parameter language model locally with a 1-million-token context window, according to Nvidia’s press release.
The chip delivers 1 petaflop of AI compute in a form factor slim enough for laptops with all-day battery life, alongside compact desktop PCs. Nvidia claims it can render ultra-large 3D scenes over 90 GB (90 gigabytes), edit 12K 4:2:2 video, generate 4K AI video, and play AAA games at 1440p resolution at over 100 frames per second.
The agent play
The deeper bet is on AI agents. Nvidia and Microsoft collaborated on new Windows security primitives and a runtime called NVIDIA OpenShell that lets agents run on-device under user-defined policy controls. OpenShell can intelligently route queries to local or cloud models based on privacy policies, and disguise personal information in queries sent to cloud services.
Leading agent frameworks are already onboard. Hermes Agent (from Nous Research) and OpenClaw are building native Windows apps on the RTX Spark stack. “RTX Spark and NVIDIA OpenShell give Hermes users a powerful and secure environment for agents to run and work alongside you,” Nous Research CEO Dillon Rolnick said in the announcement. “You realize you’re buying a full-fledged assistant, not a typical laptop.”
The message from Nvidia CEO Jensen Huang was unequivocal: “For forty years, you launched apps. Click. Type. With RTX Spark and Microsoft Windows, you ask — and the PC does the work.”
A $200 billion bet
Huang told investors on Nvidia’s May earnings call that he sees a $200 billion total addressable market for CPUs in the age of AI agents. “We’ll have billions of agents, and those billions of agents will all use tools. And those tools are going to be like PCs, just like us humans using PCs today,” he said. Nvidia claims to have already booked $20 billion in sales of its Vera server CPU, released earlier this year.
The RTX Spark PC lineup spans from slim laptops to desktop machines. Pricing hasn’t been announced, but the closest analogue is Nvidia’s existing DGX Spark mini-computer, which sells for approximately $4,800. Whether RTX Spark systems can undercut that figure to compete with Apple’s Mac lineup — including the Mac Mini popular for running local agents — remains unanswered.
Nvidia’s second attempt at Arm Windows
This is not Nvidia’s first foray into Arm-based Windows PCs. In 2013, Microsoft took a $900 million write-down on its Nvidia-powered Surface RT tablets, and OEM partners including Dell abandoned the platform. But today’s chip is built from the opposite premise: more powerful, not less. Microsoft is branding its own RTX Spark machine as the “most powerful Surface Laptop ever built” — the Surface Laptop Ultra.
More than 100 Windows software developers have signed on, including Adobe, which is rearchitecting Photoshop and Premiere from the ground up for RTX Spark, aiming for 2x faster AI and graphics performance.
The question is whether consumers will pay a premium for local AI agents they may not yet need — and whether Nvidia can succeed in the CPU market where every previous attempt by Arm chipmakers has struggled. If anyone has the platform leverage to pull it off, it’s the company that just reported another record quarter.
