Arm CSS for Mobile 2 delivers advanced AI-powered mobile experiences across the ecosystem
Arm launched CSS for Mobile 2 in September 2026 to power next-generation AI-driven mobile experiences, integrating new CPU, GPU, and neural technologies across flagship devices from OPPO, vivo, and Xiaomi.
Arm CSS for Mobile 2, introduced in September 2026, establishes a compute foundation for AI-native mobile experiences by combining the Arm C2 CPU cluster with SME2, Arm Mali G2-Ultra NX GPU featuring Arm Neural Technology, and system software. The platform enables responsive on-device AI and neural graphics, with CPU and GPU components already adopted by leading OEMs and game developers across the ecosystem.
Flagship smartphones such as vivo’s X500 Pro and Pro Max, powered by MediaTek’s Dimensity 9600 Pro, showcase CSS for Mobile 2’s capabilities, delivering multitasking and advanced agentic AI experiences. OPPO’s Find X10 Pro Max integrates Arm C2 CPUs and Mali G2-Ultra NX to enhance AI, photography, and gaming performance, while Xiaomi’s XRING O3 chipset extends Mali G2-Ultra NX graphics to the Xiaomi 18 Fold and Xiaomi Pad 9 Pro Max.
Mali G2-Ultra NX introduces neural accelerators tightly integrated with shader code, enabling neural graphics to run alongside traditional workloads. The GPU supports sharper visuals, smoother gameplay, and cinematic lighting within mobile power limits, demonstrated in the game Neural Dawn, which features Unreal Engine MegaLights and is available on supported Android devices.
SME2 in CSS for Mobile 2 accelerates agentic AI workloads by up to 70% compared to the previous generation, with performance gains validated in Google’s Gemma 4 E2B model. Google’s AI Edge software stack, including LiteRT and XNNPACK, leverages SME2 for automatic CPU acceleration, while the AI Edge Gallery app enables users to run Gemma models locally with SME2 support on compatible devices.
