The Difference Between Pentium D & Pentium Dual Core

Pentium D and Pentium Dual Core are two different families of microprocessors that were developed by Intel. The Pentium D and Pentium Dual Core are both dual-core microprocessor families that contain a number of different models.

History

Intel launched the Pentium D family in 2005, and followed up one year later with the Pentium Dual Core family, in 2006.

Pentium Dual Core

The Pentium Dual Core family is comprised of 20 different models. With the exception of 3 models that use a Socket 1156 socket type, all Pentium Dual Core's use Socket 775 (the physical structure type). Dual Core microprocessors have a processing speed average that is slightly less than the Pentium D, with speeds that range from 1600 MHz to 3333 MHz. Dual Core microprocessors are comprised of models that have a bus speed of 800 MHz or 1066 MHz. They also have L2 cache sizes that vary, with sizes of 512 kilobytes, 1024 kilobytes, and 2048 kilobytes.

Pentium D

Pentium D microprocessors are made up of 13 different models. Like the majority of Pentium Dual-Core models, Pentium D microprocessors utilize a Socket 775 socket type. Their processing speed ranges from a low of 2667 MHz, to a high of 3600 MHz. Compared to the Dual Core family, Pentium D microprocessors are capable of slightly less bus speeds, with speeds of 533 MHz and 800 MHz. Their L2 cache size capabilities are also higher than Pentium Dual Core capabilities, varying between 2048 kilobytes and 4096 kilobytes.
