With the advent of the era of artificial intelligence (AI), mobile phones are becoming more intelligent, user experience is becoming more immersive, and consumers' demand for mobile phone computing power is also increasing. In response, we announced the launch of the Arm Terminal Compute Subsystem (CSS) , which not only has the advantages of the Armv9 architecture, but also has the performance, efficiency and accessibility to provide excellent AI experience, and can support our partners to build chip solutions based on the Arm architecture more easily and quickly.

AI enhances the generation of text, images, audio, and video, and provides dynamic and immersive gaming environments. Arm Endpoint CSS combined with Arm Cortex-X925 reduces the time to first token response by 46%, while the Arm Immortalis-G925 GPU also improves AI/ML performance by 36% compared to its previous generation. Ecosystem collaboration raises the bar for new AI smartphone experiences and will redefine the way we live, work, and play. To ensure an ideal user experience, we recently announced a joint lab with vivo to promote deep technical collaboration in the future. This collaboration effectively combines vivo's deep understanding of the use cases and features required by today's consumers with Arm's high-performance, energy-efficient computing platform, allowing us to bring a compelling user experience on vivo's flagship device.

The core highlight of Dimensity 9400 is that it is equipped with Cortex-X925, which is our most powerful Cortex-X CPU to date. Compared with the previous generation, the IPC performance of Cortex-X925 has increased by 15%, which is enough to ensure that Dimensity 9400 is not afraid of even the most demanding tasks. The resulting improvements include faster response speed of AI applications, smoother AAA gaming experience, more sensitive application operation and consistent high energy efficiency. Dimensity 9400 has a 40% improvement in energy efficiency over the previous generation.

The Dimensity 9400 uses TSMC's advanced N3E process technology and is equipped with multiple Armv9.2 CPUs in a large core cluster, including one Cortex-X925, three Cortex-X4, and four Cortex-A720. Compared with the previous generation, the Dimensity 9400 has a 35% increase in single-threaded performance and a 28% increase in sustained multi-threaded performance. As a result, it is suitable for all types of workloads on smartphones, whether it is a "burst" workload that requires peak performance (such as app launch) or a sustained workload that requires both high performance and high energy efficiency (such as gaming and video playback).

The Dimensity 9400 uses the Armv9 CPU design, and the core of the latter lies in the SVE2 architecture function . The SVE2 architecture uses new dedicated vector instructions, which are ideal for accelerating key smartphone workloads and applications. SVE2 can increase the HDR video decoding speed by about 10%, allowing users to enjoy longer battery life when watching videos on demand on mainstream applications, while also improving the performance of computational photography algorithms by 20%, allowing higher quality photos to be taken on mobile devices.

In terms of graphics processing, by integrating the Immoralis-G925 GPU, the Dimensity 9400 has a 41% improvement in peak performance and a 44% reduction in power consumption over the previous generation, ensuring that users can enjoy an immersive visual experience and seamless multitasking without compromising battery life, while also providing better acceleration capabilities for AI use cases such as image classification, natural language processing, and speech-to-text.

Immortalis-G925 also drives improvements to ray tracing content on mobile devices, increasing the Dimensity 9400’s ray tracing performance by 40% over the previous generation, resulting in a more realistic, higher-quality mobile gaming experience.

Arm, MediaTek and vivo have also collaborated extensively in areas beyond hardware innovation, working together to optimize hardware and software to achieve ideal performance. End users will experience these performance enhancements firsthand on the vivo X200 series flagship smartphones, such as faster response times for web applications.

In terms of gaming, we also demonstrated the performance advantages of Arm ASR (Arm ASR) through our collaboration with MediaTek . Arm ASR is an excellent open source solution that can improve the resolution of mobile visual and gaming content on mobile devices based on the Dimensity series. After enabling Arm ASR, the GPU's gaming performance is greatly improved, saving power and extending gaming time.
