RTX Spark Brings Nvidia AI Muscle to Windows PCs

At Computex 2026, an annual computer trade show held in Taipei, Taiwan, Nvidia made a long anticipated announcement—a version of the company’s Blackwell GB10 superchip for Windows PCs, called RTX Spark. Originally rumored to launch in 2025, it was finally introduced at this year’s show.

It came with full support from Microsoft, which announced two new devices powered by RTX Spark: the Surface Laptop Ultra and the Surface RTX Spark Dev Box. Asus, Dell, Lenovo, HP, and MSI also announced Windows PCs with RTX Spark.

If this is triggering déjà vu, that’s for good reason. In June 2024, Qualcomm and Microsoft partnered to launch AI-focused Copilot+ PCs. Qualcomm’s Arm-based chips provided an alternative to x86-based chips from AMD and Intel used across dozens of budget and mid-range Windows laptops. It was met with mixed commercial success, however, and Intel remains the dominant supplier of chips for Windows laptops. But that doesn’t mean RTX Spark will follow the same path, as Nvidia’s involvement is an important part of the equation.

“Nvidia just has more clout and more industry weight to push and make things happen that Qualcomm couldn’t do early on, and that even Microsoft struggled with,” says Ryan Shrout, president at Signal65, a third-party testing firm. “They can get game developers on board, and get software developers in the emerging AI space to pay attention.”

What is RTX Spark?

At its core, RTX Spark is an iteration of the hardware found in the DGX Spark mini-workstation, which was released in late 2025. Officially badged N1X, the silicon is Nvidia’s Blackwell GB10 “superchip,” a system-on-a-chip with 20 Arm CPU cores, 6,144 GPU cores, and support for up to 128 gigabytes of LPDDR5X memory.

There are some small differences between the mini-workstation and PC system, and the most significant is power consumption. The DGX Spark was designed for GB10 to operate with a power consumption up to 140 watts without overheating. RTX Spark laptops are likely to use less power, which may lower performance, though the details will depend on each PC maker’s particular implementation and remain to be seen.

RTX Spark will also include a neural processing unit (NPU) that qualifies the system for Microsoft’s Copilot+ certification. The NPU is used for some background AI features, like Windows Recall. However, the GPU will remain in the driver’s seat for active AI tasks, including large language models (LLMs) and image generation.

Though RTX Spark laptops took the spotlight, the news is also relevant to desktop workstations. Currently, DGX Spark ships with a custom version of Linux called DGX OS, not Windows. Nvidia says RTX Spark desktops with Windows are coming in the third quarter of 2026. Windows is also coming to Nvidia’s DGX Station, the full-sized desktop iteration of Nvidia’s hardware.

The launch of RTX Spark is of course in part an AI play, and that is taking the lion’s share of attention. But Anshel Sag,…
