Hello, 28nm chip refers to the chip manufacturing process used in electronic products, which can be used to make mobile phone chips. Mobile phone chips manufactured using the 28nm process generally have lower power consumption and higher performance, including Qualcomm's Snapdragon 400, Snapdragon 410 and other series of mobile phone chips, Mediatek's MT6589, MT6592 and other series of mobile phone chips, as well as Huawei's self-developed K3V2 and other series of mobile phone chips. However, it should be noted that the chip manufacturing process used in the mobile phone is not the only factor that determines the mobile phone, but also includes the combined influence of other factors such as design, manufacturing process flow, software optimization and so on.
The Nokia C31 is powered by a Zunigroup 9863A1 chip using a 28nm process with eight Cortex-A55 cores (1.6GHz) and a PowerVR GE8322 GPU. The phone runs fully.
