Taipei, Taiwan — At Computex 2024, Arm’s CEO delivered a keynote address that set the stage for a new era in AI computing with the introduction of the Arm Compute Subsystems (CSS) for Client. This innovative solution leverages the benefits of the Armv9 architecture, state-of-the-art 3nm process nodes, and a suite of new CPUs and GPUs designed to accelerate the development and performance of AI-driven applications on mobile devices and PCs.
Introduction to Arm Compute Subsystems (CSS) for Client
In his keynote, Arm’s CEO announced the launch of Arm Compute Subsystems (CSS) for Client, a groundbreaking compute solution aimed at enabling rapid innovation and speeding time-to-market for silicon partners. This new platform brings together validated and verified implementations of Arm’s latest CPUs and GPUs, specifically designed for the 3nm process nodes. With the increasing demand for AI capabilities, Arm CSS for Client offers the performance, efficiency, and accessibility needed to deliver cutting-edge AI-based experiences.
Unprecedented Performance and Efficiency
Breakthrough CPU and GPU Performance
Arm CSS for Client features the latest Armv9.2 CPUs and the new Immortalis GPUs, which together provide significant performance and efficiency improvements. The new Cortex-X925 CPU, at the heart of CSS for Client, delivers the highest year-on-year IPC uplift in the history of Cortex-X, resulting in a 36% increase in single-thread performance. This enhancement is critical for AI applications, delivering a 41% uplift in performance for on-device generative AI tasks such as large language models (LLMs).
Supporting the Cortex-X925 is the Cortex-A725 CPU, which offers a 35% improvement in performance efficiency, making it ideal for AI and mobile gaming use cases. Additionally, the refreshed Cortex-A520 CPU and updated DSU-120 contribute to overall power efficiency and scalability for consumer devices.
The Immortalis-G925 GPU stands out as Arm’s most performant and efficient GPU to date, providing a 37% increase in graphics performance and a 34% boost in AI and ML network performance. This GPU is designed for flagship smartphones but is also part of a scalable family including the Mali-G725 and Mali-G625 GPUs, targeting a broad range of devices from premium handsets to XR wearables.
AI-Optimized Software Integration
Arm introduced the new KleidiAI software, which integrates seamlessly with popular AI frameworks like PyTorch and TensorFlow. KleidiAI provides developers with frictionless access to optimal performance on Arm CPUs, supporting key Arm architectural features such as NEON, SVE2, and SME2. This software dramatically improves the performance of computing applications by leveraging a wide range of Arm’s acceleration technologies.
