NVIDIA CUDA 13.4 Adds Windows on Arm Support [2026]

NVIDIA released CUDA Toolkit 13.4 on September 9, 2026, introducing native CUDA support for Windows on Arm. This update allows developers to compile and run CUDA applications on Windows Arm64 systems, closing a gap that existed since CUDA's inception in 2007. The toolkit offers two workflows: native compilation on Windows Arm64 machines and cross-compilation from x86-64 systems. Developers must install an R616-series Developer Driver to utilize the new features. The release aligns with the upcoming launch of NVIDIA's RTX Spark laptops, built on the N1X Arm platform. The toolkit is designed for RTX Spark devices, which leverage NVIDIA’s Blackwell GPU architecture. Current Windows on Arm devices can also begin using the toolkit in preparation for the hardware launch. The initial feature set for Windows Arm64 is narrower compared to x86-64, but developers are encouraged to adapt their applications for the new environment.

Microsoft celebrates major progress with Windows 11 on Arm PCs, confirms Windows on Arm is now “a first-class platform for any workload” and that “customer demand is growing”

Microsoft has announced advancements in the Windows on Arm platform, highlighting the upcoming addition of NVIDIA's RTX Spark SoC later this year, which will enhance the existing Qualcomm Snapdragon X platform. By fall 2026, devices from manufacturers like Microsoft Surface, ASUS, Dell, HP, Lenovo, and MSI will feature RTX Spark technology. There are currently over 7,000 compatible applications for Windows on Arm, available on the "Works on WOA" website. Users can engage in discussions about these developments on Reddit at r/WindowsCentral.

Nvidia’s RTX Spark could caplitalize where Qualcomm’s Arm-based efforts have not — following the expiration of Qualcomm’s Windows on Arm deal, Nvidia stands poised to pick up the slack

Nvidia unveiled its RTX Spark superchip on May 31st, combining a 20-core Arm-based Grace CPU with a Blackwell RTX GPU, marking its entry into the Windows PC market. The chip features up to 128GB of unified memory, 1 petaflop of AI compute capability, and 6,144 CUDA cores. It will debut in laptops and compact desktops from manufacturers like ASUS, Dell, HP, Lenovo, Microsoft Surface, and MSI, with Acer and GIGABYTE expected to follow. Microsoft collaborated with Nvidia to develop new Windows security features for on-device AI agents. The RTX Spark, previously known as N1X, has been in development for three years, with initial reports in 2023 and delays attributed to advancements in Arm technology and notebook demand. Microsoft's Windows on Arm initiative, previously exclusive to Qualcomm, has opened opportunities for MediaTek, Nvidia, and AMD. The RTX Spark aims to enhance local AI applications, with Adobe reengineering its software for the platform and over 100 software vendors supporting it. However, challenges remain, including reliance on x86 emulation and delays in the next-generation Windows on Arm platform. Pricing details are scarce, but the RTX Spark is expected to be positioned at a premium price point.

NVIDIA N1 and N1X: new leak data show multiple Windows-on-Arm chips for notebooks

NVIDIA is preparing to enter the Windows PC market with at least two distinct ARM chip product tiers, the N1 and N1X, although these remain unverified. The N1X will have two configurations: a larger variant with 20 CPU cores (10+10 layout), 48 Blackwell Streaming Multiprocessors (6,144 CUDA cores), and a smaller variant with 18 CPU cores (9+9 layout) and 40 SMs (5,120 CUDA cores). The power envelope for the N1X models is projected to be between 45 to 80 watts. The smaller N1 variant is expected to have a power range of 18 to 45 watts and up to 20 SMs. Retailer listings suggest that Lenovo may offer models like the Yoga Pro 7 15.3 with NVIDIA N1X configurations and options for 32 GB RAM and 1 TB SSD. NVIDIA and Microsoft plan to unveil the first Windows PCs featuring NVIDIA chips, with potential vendors including Microsoft’s Surface brand and Dell. The success of the Windows-on-Arm platform will depend on factors beyond CUDA core count, such as native applications, drivers, power management, and gaming compatibility. NVIDIA's extensive resources, including CUDA and AI frameworks, may give it an advantage over competitors like Qualcomm.

Lenovo Legion 7 and the N1X leak: Will this be the first serious Windows-on-ARM gaming laptop?

A recent discovery involving Lenovo's model listings revealed a "Legion 7 15N1X11," which may indicate a 15-inch Legion model of the 11th generation potentially powered by an NVIDIA N1X platform. This model deviates from the typical Intel, AMD, or Qualcomm nomenclature associated with gaming laptops. While the specifics of the device's final specifications and potential release remain unverified, the mention of an ARM gaming laptop raises questions about the future of Windows on ARM, a segment that has struggled in gaming. NVIDIA has introduced the GB10 Grace-Blackwell superchip, which integrates an ARM CPU with Blackwell GPU technology, and speculation exists that the N1X might share similarities with this chip. The current Legion 7a generation features AMD Ryzen AI 400 processors and GeForce RTX laptop GPUs. Windows 11 has improved compatibility for ARM, but challenges remain with games relying on anti-cheat drivers not designed for ARM systems. The reference to a 15-inch model suggests a potential transition to a dedicated chassis for this specific SoC class.
