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.
Types of Dual Core Processors
Kinds of Dual Core Processors include the following:
64-bit dual core processors
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.
Extended 64-bit dual core processors
Extended 64-bit processors have the same capacity as 64-bit processors, but they can run 32-bit and 64-bit programs at the same time.
They are commonly used for applications that require much processing power, such as computer-aided design (CAD) and animation programs.
Choosing Dual Core Processors (Buying tips)
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.
