AMD OpenCL beta targets CPUs, GPUs

What are multicore devices?
A microprocessor that combines two or more independent processors into a single package or IC. Multicore chips allow for greater increases in computing power as compared to a single CPU continually made to run faster. In general, multicore microprocessors allow a computing device to exhibit some form of thread-level parallelism (TLP) without including multiple microprocessors in separate physical packages. This form of TLP is often known as chip-level multiprocessing.

What does CPU stand for?
Central processing unit (CPU) is the computing part of the computer. Also called the processor, the CPU is made up of a control unit and an arithmetic logic unit.
