Dual-core
A dual-core processor is a CPU with two individual cores on the same integrated circuit or die. Each CPU has a unique cache, enabling the dual-core processor to order, execute, and store data twice as fast as a standard single processor unit. A single-core processor has only one CPU forcing some cached information to be retrieved from the system's random access memory (RAM) or other storage device. This process slows performance of a computer to the maximum speed of the device that handles the data outside the cache of the CPU. A multi-processor system is different from a dual-core processor in that there are two separate CPUs, each with its own resources. Although a multi-processor system has the capability to be faster than a dual-core system, the dual-core processor does not necessitate a new motherboard. In order for a system to utilize a dual-core processor, the operating system must be able to recognize multi-threading. In addition to this need in the operating system, the software being used must also support simultaneous multi-threading technology (SMT).
