Definition - What does Quad-Core Processor mean?
A quad-core processor is a type of computer processor architecture that has four processor cores embedded within a single processor dye.
Each of the four cores can execute and process instructions independently of the other cores.
Techopedia explains Quad-Core Processor
A quad-core processor is a multiprocessor architecture that is designed to provide faster processing power. It is a successor to the dual-core processor, which has two processor cores. Quad-core processors integrate two dual-core processors within a single processor. The two separate dual cores communicate with each other using processor cache. A quad-core processor can execute multiple instructions simultaneously, meaning that each core can be dedicated for separate instruction.
Although quad-core processors increase the processing performance of a computer by a significant margin, system speed also depends on other computing components to deliver overall computing performance.
Intel and AMD are popular vendors of quad-core processor technologies.
