Nvidia CEO Jensen Huang has unveiled RTX Spark, the company's first chip built for Windows PCs, and he says it will help "reinvent the PC." Announced at Computex on June 1, 2026, the Arm-based superchip pairs a 20-core CPU with a Blackwell RTX graphics processor and up to 128 GB of unified memory in a single package. Nvidia says it can deliver up to one petaflop of AI performance while staying power-efficient enough for thin laptops. It was developed with Microsoft and MediaTek, and laptops from brands including Acer, Asus, Dell, Lenovo, MSI and Microsoft's Surface Laptop Ultra are expected this autumn.

The pitch is that powerful AI, including personal AI agents, can run on your own device instead of in the cloud, with no servers or subscriptions and even without an internet connection. But some of the boldest claims spreading online are not confirmed, including the 3nm process, a 14mm thickness, "zero throttling," and 100+ FPS in major games on battery, and the ability to run 120-billion-parameter models locally has not been independently tested. Independent benchmarks are not possible until the laptops ship, and reviewers note that gaming compatibility on Arm is still a question. The traditional PC is also not dead, since Intel and AMD still dominate Windows laptops, although their shares fell on the news. For now, RTX Spark is a serious challenge to the old model, not yet its replacement.
