A hobbyist benchmarks running Qwen 3.6/3.8 MoE models on a £300 Snapdragon X mini PC (optionally dual-boxed via USB4), comparing llama.cpp, Janas, and their own unreleased ToRc engine, hitting 315 tok/s read on the 35B A3B model. The post details hardware setup, MTP head usage, and NPU-assisted CPU inference results.

Qualcomm has legally established that Arm breached its license, prevailing in their licensing dispute despite a nominal $2 award.

微软 Surface Laptop Ultra 搭载 Nvidia RTX Spark 平台，宣称一台设备即可兼顾开发、AI 与游戏，评测显示其基本兑现了大部分承诺，但价格高昂且 ARM 生态仍待完善。

The Verge reviews Microsoft's Surface Laptop Ultra, a $5,900 ARM-based laptop co-engineered with Nvidia featuring RTX Spark chips for running AI models locally. The hardware rivals the MacBook Pro with a stunning MicroLED display and magnetic USB-C charging, but local AI capabilities still feel like a beta experience.

A user benchmarks a £300 Snapdragon X mini PC running 35B and 80B local models on CPU alone, and ports the Janas MoE offloading tool to ARM with NEON kernels to squeeze out usable token rates. Results show 80B models running on 32GB RAM and hints at multi-box USB4 distributed inference.

Nvidia's RTX Spark Arm-powered laptops launch October 16th, promising to run all Windows apps, games, and AI workloads via Microsoft's Prism emulator — aiming to avoid the fate of the failed Windows RT era.

作者在为 AArch64 从零编写自制操作系统 floss 时，深入分析了 ldaxr/stxr 独占内存访问在 QEMU 上正常、却在真实硬件上触发异常的问题，探讨了自旋锁、异常处理、虚拟内存、内存类型与缓存属性之间的复杂交互。

Jeff Geerling reviews the Radxa Dragon Q8B, a $209 Snapdragon 8cx Gen 3-based SBC that on paper outperforms the Raspberry Pi 5 with twice the CPU cores, faster GPU, built-in NPU, dual 2.5G networking, and multiple M.2 slots — though software setup remains a hurdle. It may signal Qualcomm's entry into the hobbyist SBC market.

Google acknowledged that some Android apps may not run smoothly on its new Intel-based Googlebook laptops because many apps were originally designed for Arm chips, saying a 'small handful' of complex apps need developer tuning.

Raymond Chen explains why Windows hot-patching exists for x86-32, x86-64, 64-bit ARM, and Itanium but not for older or other architectures like 32-bit ARM, MIPS, Alpha AXP, PowerPC, and SH-3: most predated the hot-patching rules, while 32-bit ARM was excluded because hot-patching is a Windows Server feature and no Server version existed for that architecture.

A two-day hackathon at San Francisco State University, organized by Meta and Arm, focused on building AI applications on the edge using ExecuTorch on Arm-powered devices, with technical talks, workshops, and prizes.

Arm announces new C2-Ultra CPU and G2-Ultra NX GPU IP cores for mobile devices and CSS N4 for datacenters, with technical improvements and comparisons to previous architectures.

IBM unveils a next-generation dual-architecture processor for IBM Z and LinuxONE that natively supports both Arm and IBM Z instructions, featuring 2nm technology and AI accelerators to enhance enterprise computing options.

A small experiment comparing the RISC-V RVA23 and ARMv9 computer architectures.

David Chisnall presents CHERI, a hardware capability architecture enabling memory safety and fine-grained compartmentalization through ISA extensions such as ARM Morello, RISC-V, and CHERIoT microcontrollers. The talk emphasizes the importance of practical programming models for secure isolation.

At OCP APAC 2026, AMD, Arm, and Microsoft executives argue that agentic AI workloads will increase CPU demand significantly, potentially shifting CPU-to-GPU ratios from 1:4 to 1:2 or even 1:1, while Microsoft positions its Cobalt 200 chip as an 'agent-native CPU'.

Jeff Geerling's benchmarks show Intel's Core 5 320 in a Dell XPS 13 matching or beating Apple Silicon on performance per watt, suggesting x86 can compete with ARM on efficiency.

RPCS3's ARM port now runs 60% faster and draws 25% less power after fixing a busy-wait timer bug, replacing x86 pause with ARM ISB, and reworking LLVM code generation. The gains come from low-level ARM optimizations driven by a cheap Android handheld test device.

An analytical critique of NVIDIA's Vera whitepaper, examining the Olympus core's impressive architecture while arguing that the paper's anti-x86 narrative and benchmark claims are overstated, with independent testing suggesting the hardware is genuinely strong.

Oracle is halving its Always Free ARM compute limits, cutting Ampere A1 allowance from 4 OCPUs/24 GB to 2 OCPUs/12 GB, with automatic termination of excess instances starting August 18, 2026. The article explains the change and steps users should take to shrink or consolidate before the deadline.
