Under the hood, the nubia Z5S was equipped with a Qualcomm Snapdragon 800 chipset, built on a 28 nm process. The quad-core 2.3 GHz Krait 400 CPU and Adreno 330 GPU provided robust performance for a range of applications, from basic tasks to more demanding gaming exploits. The phone ran on Android 4.2.2 Jelly Bean, which at release was relatively modern, offering a stable and user-friendly experience.
