Microsoft Calls In NVIDIA CEO Jensen Huang For Its Biggest Windows Event In Years

Microsoft will hold a Windows event on October 7 in San Francisco, marking its first major dedicated Windows gathering in over two years. The event will feature CEO Satya Nadella, Windows and Surface chief Pavan Davuluri, and NVIDIA CEO Jensen Huang, focusing on the impact of local AI on personal computing. A highlight will be the Surface Laptop Ultra, designed to compete with the MacBook Pro, featuring a custom NVIDIA RTX Spark SoC, an NVIDIA Blackwell GPU, up to 128GB of RAM, and the ability to run complex AI models on-device. Microsoft has also introduced a Workload Profile Scheduling system for efficient task distribution across CPU cores and optimized its Prism emulation layer for legacy x86 applications on ARM systems. The event is not expected to announce Windows 12, as Microsoft will focus on enhancing Windows 11. Major hardware partners like Dell, Lenovo, and ASUS are also involved in the RTX Spark ecosystem.

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.

First Xiaomi, then the world: why Arm might give phone gaming a huge graphics boost

Arm's DLSS for Android is set to be released soon, starting with the Xiaomi 18 Fold in China. The new Arm Mali G2-Ultra NX graphics processor inside the custom Xring O3 chip promises to enhance mobile gaming by providing PC-like technologies to improve game performance without using more power. This technology includes AI gaming graphics accelerators that can eliminate jagged edges in games and offer features similar to Nvidia's DLSS, such as AI upscaling, frame generation, and ray reconstruction. The new graphics tech is expected to be available in various devices beyond Chinese phones, including tablets and Chromebooks. The technology is aimed at improving gaming experiences while maintaining battery life and will be integrated into games like Where Winds Meet, Infinity Nikki, and Arena Breakout: Infinite.

Windows on Arm just hit 7,000 compatible apps. It’s still not enough

Windows on Arm offers energy-efficient performance with extended battery life, minimal heat generation, and quiet operation. However, compatibility issues arise as most applications are designed for x86/x64 systems, making it difficult for Arm-based systems to run them effectively. A significant resource, the "Works on Windows on Arm" website, lists over 7,000 apps and games that support Arm architecture, including popular applications like Adobe Photoshop and Firefox. Microsoft plans to launch Arm-based computers from major manufacturers, but the number of compatible apps is still a small fraction of those available for traditional Windows systems. For non-native Arm applications, Microsoft provides an emulation solution through Prism in Windows 11, though this does not perform as well as native support. Gamers face challenges with current Snapdragon laptops, which struggle to deliver a smooth gaming experience, and the existing app offerings do not meet the gaming community's needs.

Microsoft Touts Windows on Arm Ahead of Nvidia RTX Spark

In June, Microsoft and Nvidia introduced the Windows on Arm-based RTX Spark chipsets, signaling a shift in personal computing. New PCs, including models from Microsoft’s Surface line, are expected soon, driven by increasing customer demand for efficient Windows on Arm devices. This interest follows Apple's announcement of its Arm-based chips, prompting Microsoft to adapt to the changing market. Klaus Diaconu from Microsoft indicated that Nvidia RTX Spark PCs from manufacturers like ASUS, Dell, HP, Lenovo, and MSI are set to launch in fall 2026. The growth of the Windows app ecosystem is also noted, with over 7,000 verified apps and games available for Windows on Arm. Microsoft’s App Assure program collaborates with developers to enhance application representation in this ecosystem. Significant advancements in compatibility have been reported across various app categories since the last update. Diaconu emphasized that Windows on Arm is now characterized by a growing ecosystem of PCs and applications that meet consumer needs. Microsoft has not explicitly referenced "Windows 11" in its communications, focusing instead on the "Copilot+ PC" narrative.
