A technical deep dive explains why translating x86 software to run on ARM chips runs into a persistent obstacle: x86's strict Total Store Ordering (TSO) memory model clashes with ARM's much more relaxed memory consistency rules. The piece walks through why this mismatch affects essentially every emulated multi-threaded application and outlines the various workarounds engineers use, noting some cases where no clean fix exists.
Arm Holdings CEO Rene Haas told CNBC's Jim Cramer that his confidence in reaching $2 billion in revenue for the company's new AGI CPU has increased since the July earnings call. Arm first flagged $2 billion in demand visibility in May, double its earlier $1 billion estimate, but had held off raising guidance while working to secure sufficient manufacturing capacity.
Valve has opened reservations for its standalone Steam Frame VR headset, priced at $1,059 for 256GB storage or $1,299 for 1TB, with sign-ups closing September 17 and invitations sent starting September 18. Every unit includes two controllers, a 6GHz wireless adapter, and a native Arm64 rebuild of Half-Life: Alyx that runs directly on the device.
OpenArm is a newly released open-source 7-degree-of-freedom humanoid arm built for physical AI research, offering high backdrivability and compliance for safe interaction with humans. A complete bimanual system costs $6,500, and the project includes a standardized 'OpenArm Cell' testing environment for reproducible research. The team is inviting contributors, researchers, and manufacturers to join development.
A tech guide outlines practical settings changes Windows 11 users can make to extend laptop battery life, noting that x86-based machines remain more power-hungry than ARM alternatives and that Windows 11 itself carries performance overhead. The top recommendation is lowering screen brightness via the Win + A shortcut, alongside other adjustments that trade some performance for longer runtime.
Microsoft has patched a bug that stopped Teams and the new Outlook for Windows from launching on ARM-based devices like the Surface Pro 11 and Surface Laptop 7. The issue, triggered by August 2026 security updates (KB5121003), mainly hit new or freshly imaged PCs without Microsoft Store updates. The fix arrived with the September 8 cumulative update, KB5124012.
Arm announced a wave of agentic AI-focused updates to its IP portfolio at its Arm Everywhere China event, spanning mobile devices, robotics, and cloud/enterprise infrastructure. Among the highlights is the Mali G2-Ultra NX GPU, which integrates neural accelerators capable of delivering AI graphics performance at under one watt of power for mobile devices.
Arm has announced its new C2-Ultra CPU architecture, the successor to last year's C1-Ultra, which is expected to appear in Samsung Exynos and MediaTek Dimensity chips around 2027, and possibly Google's Tensor G7. Arm claims up to 15% peak performance gains over its predecessor, though most of that comes from a higher 4.45GHz clock speed rather than architectural changes, while power efficiency improves by 38% at equivalent performance thanks to a 2nm process and larger L2 cache.
Arm has launched the Mali G2-Ultra NX, described as its first AI-native Mali GPU, which embeds dedicated neural accelerators directly into shader cores alongside a new execution engine and third-generation ray tracing hardware. The design lets neural graphics workloads run in parallel with traditional graphics and compute tasks, sharing memory and cache resources to cut data movement and power use while aiming for desktop-quality visuals on phones.
Arm has introduced its new Mali G2 series of mobile GPUs, led by the G2-Ultra, which brings neural network-based resolution upscaling to smartphones for the first time. The chip also delivers modest rasterization gains of roughly 9-14% in gaming benchmarks over the previous G1-Ultra, alongside a reworked execution engine with doubled shader registers that better supports advanced rendering techniques like Unreal Engine 5's Lumen and Nanite.
Arm has introduced its next-generation Neoverse CSS N4 semi-custom compute subsystem, codenamed Ranger, built on TSMC's N3P process node. The platform allows cloud and chip partners to configure between 8 and 128 Arm Neoverse N4 cores per die, clocked up to 3.8 GHz, with support for DDR5 or LPDDR6 memory, up to 256 MB of L3 cache, and 128 lanes of PCIe 7/6 or CXL 4.0.
Arm has introduced its CSS for Mobile 2 platform for chipmakers, featuring a redesigned GPU called the Mali G2-Ultra NX that it describes as its first AI-native graphics processor. The chip uses three AI techniques—neural super sampling, frame rate upscaling, and denoising—to boost resolution and frame rates directly within the graphics pipeline, while updated CPU clusters target AI agent workloads. The technology is expected to appear in premium Android phones starting in 2027.
