Introduction

As Al era accelerates, Arm is redefining mobile experiences with the release of Al-optimized CSS for Client. lt is designed to deliver greater uplift of performance, efficiency, and scalability for consumer devices, benefiting developers and end-users.

Arm CSS for Client: Pushing the Boundaries of Al Performance for Premium Mobile

Arm CSS for Client targets consumer devices, integrating the latest Amv9.2 CPUs, Arm's Immortalis GPU, production ready physical implementations for CPU and GPU on 3nm, as well as the latest Corelink System Interconnect and System Memory Management Units (SMMUs) and the Kleidi software providing developers with frictionless access to the best performance possible on Arm CPUs. CSS for Client is Arm's fastest platform for Android to date, with significant improvements across key benchmarks and general compute use cases compared to the TCS23 platform.

Arm CSS for Client can address demanding real-life Android workloads with a greater than 30 percent increase on compute and graphics performance and 59 percent faster Al inference for broader AI/ML workloads. Additionally, the new Cortex-X925 CPU provides a 41percent performance uplift to improve the responsiveness of on-device GenAl, while the Immortalis-G925 GPU can deliver 34 percent more performance for multiple Al networks. Through the platform, Arm is building the future of consumer computing for the Al-based experiences of today and tomorrow.

Arm CSS for Client: Enablement of New-Generation On-device Al Experiences

CSS for Client is the purpose-built plat-form for the next generation of Al experiences across a broad spectrum of consumer devices.On mobile, users will experience Android like never before. Amv9.2CPUs have chosen 2+4+2 CPU cluster which helps improve performance of important use cases like app launch and Al performance on the CSS platform. CoreLink increases the L3 cache size from 8MB to 16MB, which is shared across all cores in the cluster, will contribute to a further speed-up for compute heavy workloads. On the GPU side, Arm Immortalis-G925 has opted to implement 14 sharer cores with 4MB of shared L2 cache to make use of area reduction with 3nm process. CSS for Client achieves stunning graphics and console-level gaming performance through theImmortalis-G925 for flagship smart-phone devices, which is built on the 5th Gen GPU architecture.

As part of CSS for Client,working with leading foundry partners,Arm is co-designing and delivering CPU and GPU physical implementations, which includes tape-out ready Cor-tex-X925 CPU and Immortalis-G925 physical implementations for 3nm.This helps partners to access the full PPA (power,performance and area) benefits on the 3nm process, while shortening silicon development and deployment timelines through the production-ready silicon solutions. It also gives partners the flexibility to build market-specific, differentiated CPU clusters and GPUs using CSS for Client.

With maximizing the PPA benefits, enabling more Al capabilities and application experience for premium platforms, Arm CSS for Client can help Arm's partners to create advance SoCs, diving the evolution of Am ecosystem.

Arm CSS for Client: the Technology Foundation for AI Everywhere

Arm architecture is the world's pervasiveness computing platform being the foundation of Al innovation. As of now, Arm partners have been shipping 290 billion Am-based chips to the market.

As Al workloads continue to get more compute intensive and complex, Am is laying the foundation for next-generation AI, with more compute and graphic performance, better interfering efficiency,more Al applications enabled, and lower power consumption at the heart of the latest Amv9.2 CPU cluster. These benefits are scalable across a broad range of consumer devices, from flagship smartphones and AI PCs right through to mainstream mobile,XR and wearable devices as part of Arm's commitment to enable AI everywhere.

Arm is driving the Al evolution and expects that more than100 billion Arm-based devices will be Al ready by 2025. Armv9 CPU technology has been adopted in silicon across leading Al-enabled flagship smartphones, including Google Pixel 8 and Pixel 8 Pro (Goo- gle Tensor G3 chipset), XiaomRedmi K60 Ultra, and vivo X100 (MediaTek Dimensity9300 chipset).

In the ever-evolving, fast paced age of Al Arm is steadfast in support for the over20 millions of developers worldwide and ensuring that they have access to the performance, tools and software libraries needed to seamlessly create the next wave of stunning Al enabled experiences. This is why Arm launched Arm Kleidi, abroad program of software and software community engagements for accelerating AI.

Arm CSS for Client is the platform for the next-generation of smartphones and PCs. With these technology improvements, ecosystem partners will be able to seize the opportunity of Al by enabling advanced features to build future on-device Al experiences, on Arm.
