what is a quad core processor in a laptop
CPUs have a clock speed â think of it as how fast the CPU does work. (Thatâs actually an imperfect analogy as the truth is a lot more complicated, but it will have to do for now.) For example, Intelâs Core i5-3330 processor has a clock speed of 3 GHz and is a quad-core processor, which means it has four cores.
