Quad-Core

Example: "Apple's Mac Pro workstations have quad-core CPUs."

Quad-core CPUs have four processing cores. These cores act as separate processors, but reside in a single chip. A quad-core CPU can process instructions using all four cores at the same time, but the computer's software must support multiprocessing in order to use the four cores effectively.
