Question

what is the fundamental difference between CPU and GPU when both of them do some calculations ?

Answer 1

On the hardware end,

CPUs can handle complex instructions but have only few cores, around 16 or so.

GPUs can handle simple instructions but thousands of cores.

Each core can handle one “calculation” at a time (ignoring pipelining). Having more cores means more parallel computing.
