Microsoft Unveils Surface Laptop Ultra with Nvidia RTX Spark Chipset

Microsoft has introduced the Surface Laptop Ultra, a high-end Windows laptop featuring Nvidia’s new RTX Spark chip, marking Nvidia’s entry into Arm-based PC processors. The device underwent rigorous testing at Microsoft’s Redmond lab before launch, aiming to compete directly with the MacBook Pro in performance and capabilities. The Ultra also supports gaming and offers a sleek design similar to Apple’s space gray options.

Microsoft announces Surface Laptop Ultra release date and pricing

Microsoft has confirmed that the Surface Laptop Ultra will launch on October 16th, with starting prices at $2,599 for the base model. The device features a 15-inch HDR touchscreen, Nvidia RTX Spark chip, and a range of ports, targeting high-end users in creative, gaming, and AI fields. Higher configurations are available, with the most expensive reaching nearly $6,000.

Google confirms some Android apps run worse on Intel-based Googlebooks than Qualcomm models

Google told Android Authority that certain Android apps may not perform as well on its new Intel-powered Googlebooks compared to versions running Qualcomm's Snapdragon X Elite chips. The company said most apps run smoothly on both platforms, but a subset of complex apps or games originally built for Arm processors need developer tuning to work well on Intel's x86 architecture. Google did not identify which apps are affected, and the disclosure came only after the five new Googlebooks went on sale.

GrapheneOS says Pixel 11 lacks ARM memory tagging hardware support

GrapheneOS reports that after a week spent building a partial port for the Pixel 11 series, it cannot complete the port because the devices lack working support for ARM hardware memory tagging (MTE) in software, firmware and likely hardware. The project notes the Pixel 8 introduced hardware MTE in October 2023, but neither Android nor the Pixel OS enabled it by default, and Android 16's Advanced Protection Mode only turns it on for a handful of processes. GrapheneOS adds that Pixel 11 still gains some security upgrades, including post-quantum verified boot, AOSP IMS replacing Samsung Shannon, and a Titan M3 chip.

Google confirms some complex Android apps falter on Intel-based Googlebooks

Google told Android Authority that while most Android apps run fine on both Intel and Qualcomm Googlebooks, a small number of complex apps or games need extra developer tuning to perform well on Intel x86 devices. Google did not specify which apps are affected or describe the exact compatibility problems. The company said it is working with app developers, Intel and Qualcomm to improve optimization across the platform.

Google confirms Android app compatibility gaps on Intel-based Googlebooks

Google told Android Authority that most Android apps run well on both Intel and Qualcomm-powered Googlebooks, but acknowledged that a small number of complex apps and games need extra developer work to perform properly on Intel chips. The company said this stems from many Android apps originally being built for Arm processors rather than Intel's architecture.

Qualcomm, Arm bring DLSS-style AI graphics upscaling to next-gen mobile chips

Qualcomm unveiled the Snapdragon 8 Elite Extreme Gen 6 at Snapdragon Summit 2026, featuring new Adreno Neural Fusion GPU technology that uses AI to upscale resolution, generate extra frames, and extend battery life during gaming. Separately, Arm introduced its Mali G2-Ultra NX GPU with similar AI upscaling, frame generation, and a denoiser for effects like ray tracing, which will appear in chips from companies such as MediaTek.

Developers port Valve's new Arm-based SteamOS to Android gaming handhelds

Valve released an Arm version of SteamOS following its Snapdragon-powered Steam Frame headset, and developers hashtagbasit and MaSieS4Fun quickly adapted it to run on Android handhelds. The port can be installed from a microSD card on devices including the AYN Odin 2 family, AYN Thor, Retroid Pocket 6, and several AYANEO Pocket models, letting users try SteamOS without wiping internal storage. Android Authority tested the MaSieS4Fun build on an AYN Odin 2 Portal and reported it booted and set up successfully after first installing the Rocknix ABL bootloader.

Developer builds LLM-controlled robot arm using SO-101 kit and old Raspberry Pi 3

A software developer documents an experiment in robotics after nine months of intensive LLM-assisted coding, purchasing a preassembled SO-101 robot arm kit for $415 and adding a $50 webcam. He repurposed an eight-year-old Raspberry Pi 3 found in a drawer to help control the setup, aiming to give his children a tangible, hands-on project after failed attempts to interest them in building video games.

Modders port Valve's Arm SteamOS to Android handhelds via Armada project

Following Valve's official Arm64 SteamOS release for its Steam Frame headset, open-source developers have expanded the Armada project to bring a similar Linux-based Steam experience to Android gaming handhelds. The system combines the Linux kernel, Valve's Arm64 Steam build, the FEX emulator, and Proton to run Windows x86 games on Arm hardware, with support already available for devices from Ayaneo, Ayn, Retroid and Konkr.

Nordic Semiconductor engineer details debugger pitfall in nRF54L Key Management Unit

A Nordic Semiconductor engineer, newly joined to the company, describes debugging the security architecture of the nRF54L chip series by directly manipulating registers rather than writing firmware. While probing the Key Management Unit (KMU), which stores sensitive key data in a Secure Information Configuration Region only accessible in secure mode, they encountered unexpected memory values traced to how the debugger interacts with the chip's internal components rather than a flaw in the KMU itself.
