Arm unveils new Lumex AI focused smartphone CPUs with some impressive stats (www.techradar.com)

Arm has unveiled its new Lumex CPU lineup, a purpose-built compute subsystem designed to dramatically boost on-device AI performance in smartphones and wearables. Featuring the Armv9.3 C1 CPU cluster with built-in SME2 units, Lumex promises up to 5x improved AI capabilities and 3x greater efficiency over previous generations. This leap enables faster app execution with 15% speed improvements and reduced power consumption by 12%, signaling a significant step forward for mobile AI workloads. The architecture offers four CPU variants tailored to different uses—from energy-efficient cores for wearables (C1-Nano) to high-performance cores optimized for large AI models (C1-Ultra). What sets Lumex apart is its integrated platform combining CPUs, Mali GPUs, and software, including SME2-enabled KleidiAI libraries and telemetry tools, allowing developers to fine-tune models and identify bottlenecks. Notably, the Mali G1-Ultra GPU delivers 20% faster AI/ML inferencing and doubles ray tracing performance for gaming, enhancing overall device intelligence. Arm emphasizes CPUs as the universal engine for AI, addressing the current fragmentation around NPUs, and ensures Lumex-ready software compatibility, including key Google apps optimized for the new hardware. With Lumex, Arm paves the way for smarter, more efficient AI-driven mobile experiences, marking a significant milestone for the AI/ML community focused on edge intelligence and real-time on-device processing.
