Nvidia's AI Hardware Comes to Windows in RTX Spark PCs

What was announced at Computex

Nvidia and Microsoft brought Nvidia's AI hardware to Windows.

›RTX Spark is a version of Nvidia's Blackwell GB10 superchip for Windows PCs.
›It was originally rumored to launch in 2025 and was introduced at Computex 2026.
›Microsoft announced the Surface Laptop Ultra and the Surface RTX Spark Dev Box.

Asus, Dell, Lenovo, HP and MSI also announced Windows PCs with RTX Spark, signaling broad OEM support for the new chip.

Echoes of the Qualcomm Copilot+ launch

The article notes a sense of deja vu from an earlier Windows AI push.

›In June 2024, Qualcomm and Microsoft partnered to launch AI-focused Copilot+ PCs.
›Qualcomm's Arm-based chips offered an alternative to x86 chips from AMD and Intel.
›That effort had mixed commercial success, and Intel remains the dominant supplier of chips for Windows laptops.

Ryan Shrout, president at testing firm Signal65, said Nvidia has more clout and industry weight than Qualcomm to make things happen, including getting game developers and AI software developers on board.

Inside the RTX Spark hardware

RTX Spark builds on Nvidia's existing DGX Spark workstation.

›RTX Spark iterates on the hardware in the DGX Spark mini-workstation released in late 2025.
›The silicon, badged N1X, is the Blackwell GB10 with 20 Arm CPU cores, 6,144 GPU cores and up to 128 GB of LPDDR5X.
›The most significant difference from the workstation is power consumption.

The DGX Spark was designed for GB10 to run at up to 140 watts without overheating, while RTX Spark laptops are likely to use less power, which may lower performance depending on each maker's implementation. RTX Spark also includes a neural processing unit that earns Microsoft's Copilot+ certification and powers background features like Windows Recall, while the GPU stays in the driver's seat for active AI tasks such as LLMs and image generation.

Desktops, workstations and timing

The news extends beyond laptops.

›DGX Spark currently ships with a custom 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 version of its hardware.

More than an AI play

Analysts say RTX Spark matters for creators and gamers too.

›Anshel Sag of Moor Insights and Strategy thinks the AI play is mostly to appease investors.
›He says creators and gamers are also excited about RTX Spark.
›GB10 is comparable to other system-on-a-chip designs like Apple's M-series and AMD's Ryzen AI Max, all with CPU, GPU, NPU and unified memory.

RTX Spark is expected to deliver GPU performance similar to an RTX 5070 mobile GPU, which would put it ahead of competing Apple and AMD systems if accurate. Nvidia's advantage, the article suggests, may lie as much in software as in raw hardware.
