Quad-core is a processor with four identical functions on a single processor based on a single semiconductor. In other words, four physical processor cores are consolidated into one core. Enterprise IT managers are also constantly looking for ways to increase performance without increasing actual hardware coverage. Multi-core processor solutions address these needs, providing enhanced performance without the need for increased power or real space.
