Dual core processors have two processing cores on a single chip. They are recognized by the computer as two processors and function with twice the power of single-core processors. They are a popular alternative to dual processor systems, where two separate processors are mounted on a motherboard. Most dual core processors can be installed on existing sockets and do not require replacing of the motherboard.
64-bit processors can handle data widths of up to 64 bits or eight bytes. They can run applications designed for 32-bit systems, but not simultaneously with 64-bit applications.
They are ideal for general computing to moderately heavy applications, such as video editing and graphics design.
Cooling: Choose a dual core processor with a powerful fan and cooling system. Since the equivalent of two processors is housed in a single body, dual core systems can heat up quickly. Look for a processor with a fan mounted at the top to spread out the heat.
Speed: Choose a dual core processor with a speed of 2.2 GHz or higher. Heavy applications and multitasking may require faster processors. Note that speed ratings vary between manufacturers – two processors with the same indicated speed may not run at the same rate. Look up the available speeds from each brand before selecting.
