Question

Processors

Please explain in accessible language. What is the difference between a processor and a core in a smartphone?. For example, a smartphone has a Snapdragon 650 processor and a Cortex-A53 and Cortex-A72 core, although the second one is written where how, where the core is where the processor is where the CPU. Here is the specific question of what is a processor and what are processor cores and give an example and how is Cortex-A53 and Cortex-A72 correctly called in this case?

Answer 1

The processor, although more precisely in the mobile world, it is SOC / SOC (System On Chip) - a set of technologies put together that solve all kinds of problems. The chip has a percent, vidyuha and much, much more.
The processor (google definition) contains the core.
The core is a microprocessor in the processor, that is, if you get all the cores except one, everything will plow.
There are different kernels, given (A53, A72) these are the types of kernels, which together is called bigleat. A53 - energy efficient cores, A72 - high performance. In 650 snaps there are 4 A53 cores, 2 A72 cores.
Roughly speaking, the processor core is like your hand. Hands may be different, but they all carry out the given instructions. More hands (number of cores), more of their size (core type), higher their speed (clock frequency) - you complete tasks faster.
If a little differently, the processor is the head, the core is the brain. More brains - more tasks, more complex tasks and you can solve all this faster.
I already xs, how even easier to explain))

Answer 2

Previously, the processor simply calculated something according to the algorithm. As the algorithms got more complex, so did the processor. Up to the 21st century. Further, the processors were no longer optimally improved. They came up with a combination of several pieces so that they would work in parallel. So these "things" became cores, and the control and parallelization controller became a processor. IMHO)
