Nvidia has begun publishing a native Windows 11 on Arm graphics driver package tied to its upcoming RTX Spark platform, according to Windows Latest. Driver version 616.00 is reportedly currently aimed at Microsoft’s Surface RTX Dev Box rather than retail hardware, but its appearance is another sign that the first systems are moving toward launch.
The package reportedly includes an INF file named
Nvidia has not publicly described those device IDs or confirmed the lower-core configuration. The company’s official RTX Spark announcement on May 31 specified a Blackwell RTX GPU with 6,144 CUDA cores paired with a 20-core Grace CPU and up to 128GB of unified memory. That makes the driver evidence useful as a readiness signal, but not a full specification sheet for future retail machines.
Nvidia and Microsoft announced RTX Spark as a Windows on Arm platform for developers, creators, gamers and local AI workloads. Nvidia said laptops and compact desktops from Surface, ASUS, Dell, HP, Lenovo and MSI are due this fall, with Acer and Gigabyte models following later.
Microsoft has also said Windows is being tuned for the platform’s heterogeneous CPU, GPU and AI hardware. Its work includes Workload Profile Scheduling, intended to distribute jobs more effectively across RTX Spark’s 20 CPU cores, plus Microsoft Power and Thermal Framework support for platform-level performance and power management.
Windows 11 version 26H1 is central to that rollout. Microsoft’s support documentation says 26H1 is limited to new PCs with selected 2026 silicon and will not be offered as an in-place update to existing Windows 11 installations. In other words, current Arm PCs will not gain RTX Spark-specific platform support merely by updating Windows.
For IT pros and enthusiasts, the immediate implication is mostly administrative: native Arm64 Nvidia display drivers are no longer an abstract requirement for RTX Spark systems. OEM validation, firmware integration and application testing still have to follow, especially for organizations relying on specialist GPU software, older peripherals or anti-cheat-protected games.
There is nothing for existing Windows 11 users to install yet; retail RTX Spark driver support should arrive alongside the first hardware later in 2026.
The package reportedly includes an INF file named
nv_surface_woa.inf, a standard Windows driver manifest used to match hardware IDs and installation settings. Windows Latest found entries identifying two RTX Spark N1X GPU configurations: one with a 6,144-core Blackwell RTX GPU and another with 5,120 cores. It also found references to an unspecified “NVIDIA Desktop Device” and Nvidia NPU entries associated with the company’s Deep Learning Accelerator architecture.Nvidia has not publicly described those device IDs or confirmed the lower-core configuration.

What it does — and does not — prove
The driver does not establish final performance, battery life, price or game compatibility. Nvidia has made ambitious claims around CUDA, RTX, local AI and 1440p gaming, but independent testing of shipping laptops and desktops remains the meaningful benchmark.For IT pros and enthusiasts, the immediate implication is mostly administrative: native Arm64 Nvidia display drivers are no longer an abstract requirement for RTX Spark systems.
