processor
A processor is the logic circuitry that responds to and processes the basic instructions that drive a computer.

The term processor has generally replaced the term central processing unit (CPU). The processor in a personal computer or embedded in small devices is often called a microprocessor.

i3 vs i5 vs i7
Core i5 and i7 CPUs have 4 cores, while i3 CPUs only have 2. Core i5 CPUs lack Hyperthreading. Core i7 CPUs have more Smart Cache than i5 CPUs, which in turn have more cache than i3 CPUs. Core i5 and i7 CPUs have the same graphics, although the speed of that graphics will depend on the individual CPU.
