First of all we have to know that What is Processor?
Smartphone
processors always come as single-chip systems (SoC). This means that
several processor types are lasered into a single piece of silicon,
which significantly influences the working speed of the smartphone. The
clock rate and the number of cores of the central processing unit (CPU)
do not say anything about how fast the smartphone works in certain
tasks.
An
SoC consists of CPU, GPU, LTE modem, multimedia processor, security,
signal processor, AI accelerator and often also units for Bluetooth and
Wi-Fi. This variety of features makes it difficult to talk about the
fastest mobile phone processor.
The top-range Android smartphones released in the last half of 2018 or start of 2019 will pack one of the following three chips:
