On September 10, 2025, the Arm UNLOCKED Summit took place in Shanghai. During this event, Arm formally introduced the Arm Lumex Compute Subsystem (CSS) tailored for mobile devices.

This subsystem encompasses the newly - launched C1 series CPU cluster, which is built upon the Armv9.3 instruction set. Additionally, it features the Mali G1 GPU series that is equipped to support next - generation ray - tracing technology.

The C1 CPU cluster is designed to be compatible with the Scalable Matrix Extension instruction set SME2. This compatibility substantially bolsters its ability to handle AI (Artificial Intelligence) and ML (Machine Learning) workloads.

The Arm Lumex CSS platform is a comprehensive integration of the most high - performing Arm CPU, GPU, and system IP, all incorporating SME2 technology. Its primary goal is to expedite the introduction of AI devices into the market by ecosystem partners. Moreover, it aims to enable a wide array of rich experiences, including desktop - level mobile gaming, real - time translation services, intelligent assistants, and personalized applications.

It is projected that by 2030, SME and SME2 technologies will contribute an additional computing power of over 100 billion TOPS (Tera Operations Per Second) to more than 3 billion devices. This will lead to an exponential enhancement in the on - device AI performance.
