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.

Not just for AI agents: Nvidia’s RTX Spark means Arm-powered laptops for gamers, too, promising 100 fps at 1440p in the latest games

Nvidia has introduced the N1X CPU, integrated into the RTX Spark SoC, marking its entry into the laptop SoC market. The RTX Spark features up to 20 Grace CPU cores and 6144 RTX Blackwell GPU cores, supporting up to 128 GB of unified LPDDR5x memory. Major manufacturers like Asus, Dell, HP, Lenovo, Microsoft, and MSI are expected to release over 30 laptops and around ten desktop models with this technology. Nvidia's Aevermann described the RTX Spark as "the most efficient PC chip ever built," designed for both computing and gaming. Nvidia plans to introduce mini PCs powered by the RTX Spark chip this autumn, with companies like Acer, Asus, and Gigabyte preparing systems. The RTX Spark's custom Arm architecture requires Windows-on-Arm, raising performance concerns due to reliance on Microsoft's Prism emulator. Nvidia is collaborating with game developers to ensure compatibility and performance, focusing on optimizing popular games and integrating anti-cheat software.

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.

Windows security breaks ROG Xbox Ally handheld game consoles

Microsoft's Windows Smart App Control feature has flagged essential software components of the Asus ROG Xbox Ally gaming handheld as untrustworthy following a recent update to Windows 11. This issue affects the Armoury Crate CE software, which manages the hardware functionality of the device, leading to difficulties in launching games outside of the Xbox app and adjusting performance settings. The problem may stem from inadequate configuration of certificates by Asus or the need for an update to Microsoft's trusted application database. Many Windows 11 PCs do not have Smart App Control activated, and users can disable it through SETTINGS > APP AND BROWSER CONTROLS > SMART APP CONTROL SETTINGS. If users choose to disable it, they may later need to reset or reinstall Windows to reactivate Smart App Control. ROG Xbox Ally owners are currently faced with the choice of waiting for a fix or disabling the security feature.

Microsoft’s canceled dual-screen version of Windows Phone has leaked, and you can now try it on a Surface Duo

Andromeda OS, originally conceived by Microsoft in 2018 for a dual-screen phone, has been revived by developer Gustave Monce, who successfully ported a leaked build to the Surface Duo. The OS was intended to provide a new smartphone experience, featuring a home screen for note-taking and seamless navigation with gestures. Applications can open on one display and be dragged to another for multitasking. Monce has packaged the OS into a user-friendly FFU file for installation, although it is still unfinished and may have bugs. Installing Andromeda OS will erase existing Android data, but a dual-boot option is available with data loss risks. Monce has previously ported Windows 10 and 11 to the Surface Duo, highlighting Microsoft's dual-screen ambitions.
