Arm Lumex CSS Platform Unveiled with AI-Native Processing and Enhanced Gaming for Next-Gen Smartphones and PCs
Arm introduced its Lumex Compute Subsystem (CSS) platform, designed to support AI-driven experiences on flagship smartphones and next-generation PCs. The platform integrates SME2-enabled Armv9.3 CPU clusters, including C1-Ultra and C1-Pro, a Mali G1-Ultra GPU, and the C1-DSU DynamIQ Shared Unit, optimized for 3nm nodes. It aims to deliver real-time on-device AI capabilities such as assistants, voice translation, and personalization.
The SME2-enabled CPU cluster offers up to 5x AI performance uplift, 4.7x lower latency for speech-based workloads, and 2.8x faster audio generation. Applications include a Smart Yoga Tutor demo with 2.4x faster text-to-speech and a 40% reduction in LLM response time, achieved with partners Alipay and vivo. Neural camera denoising runs at over 120fps in 1080p or 30fps in 4K on a single core. The platform supports multimodal inputs—vision, audio, voice, and touch—and prioritizes on-device processing for lower latency and enhanced privacy compared to cloud-based AI.
The Mali G1-Ultra GPU provides a 2x uplift in ray tracing performance with its Ray Tracing Unit v2 and 20% better performance across graphics benchmarks for titles like Arena Breakout, Fortnite, Genshin Impact, and Honkai Star Rail. It also supports 20% faster AI inference. ...
