Nvidia enters the PC chip market with new RTX Spark Superchip

What Nvidia announced

At Computex 2026 in Taipei, Nvidia introduced the RTX Spark Superchip, its first processor aimed at mainstream Windows laptops and desktops. The chip runs Windows on Arm and combines a CPU and a GPU that share one pool of memory. Reports differ on whether the keynote fell on May 31 or June 1 because of the time difference, but coverage agrees on the content.

Reported specifications

• CPU: up to 20 Arm cores.
• GPU: Blackwell-generation graphics with 6,144 cores. Nvidia pointed to performance in the class of a mobile RTX 5070, though that comparison was not independently verified.
• Memory: up to 128 GB of unified LPDDR5X shared by the CPU, GPU and neural processing unit.
• NPU: a dedicated unit that qualifies PCs for Microsoft's Copilot+ certification and handles background AI tasks.
• Manufacturing: TSMC builds it, and MediaTek helped develop the chip.

Partners and availability

Asus, Dell, HP, Lenovo and MSI announced Windows PCs based on the chip, and Microsoft showed its own Surface devices. Nvidia said the first products arrive this fall, starting with premium laptops, with cheaper models to follow. Nvidia also reported that dozens of laptop and desktop designs are in development. Independent performance comparisons were expected only when machines went on sale.

Microsoft also previewed an SDK called Microsoft Execution Containers, which sandboxes AI agents so they can act on a PC without unrestricted access to a user's files and settings.

The challenge: Windows on Arm

Qualcomm's Arm-based Windows PCs have had mixed commercial results, mainly because of software compatibility and Intel's grip on the laptop market. Analysts quoted in coverage said Nvidia has two advantages Qualcomm lacked early on: mature graphics drivers and a long relationship with game and AI developers. Others noted that the AI-agent pitch is partly aimed at investors, and that the PC has to be a strong general-purpose machine first.

What to watch

Look for real benchmarks, battery life, price, and how well older x86 apps and games run through emulation. For another Computex hardware story, see our look at the MSI Claw 8 EX AI+ handheld.
