The display's brightness peaks at around 400 nits, making it adequately visible in various lighting conditions, although direct sunlight might pose readability challenges.
The heart of the Redmi 9AT is the Mediatek MT6762G Helio G25 chipset, built on a 12nm process. It features an octa-core CPU, including 4 cores clocked at 2.0 GHz Cortex-A53 and 4 cores at 1.5 GHz Cortex-A53, alongside a PowerVR GE8320 GPU.
