multicore - Computer Definition
A computer chip that contains more than one CPU (one processing unit). Multicore chips allow for greater increases in computing power in contrast to a single CPU continually made to run faster. Dual-core and quad-core chips came out for the x86 platform in 2005 and 2006 respectively. In the following years, multicore laptops and desktops became commonplace, and companies such as Intel, Sun and IBM introduced servers with 64-, 80- and 128-core CPUs. See SMP, dual core, triple core, quad core, octa-core, multiprocessing and Cell chip.
