A quad-core processor is a chip with four independent units called cores that read and execute central processing unit (CPU) instructions such as add, move data, and branch. Within the chip, each core operates in conjunction with other circuits such as cache, memory management, and input/output (I/O) ports.

Which is better dual core or quad-core?

Should You Get More Cores? Overall, a quad core processor is going to perform faster than a dual core processor for general computing. Each program you open will work on its own core, so if the tasks are shared, the speeds are better.

Is quad-core a good processor?

4 cores. Quad-core CPUs allow you to render video (slowly) or play games (at lower resolutions) in addition to all your regular work or school tasks. Most gamers will be fine here as long as you are not playing the most processor-intensive games and you have a dedicated GPU.
