Pentium D Vs. Pentium Dual Core
Pentium D and Pentium Dual Core are both multicore processor families. The Pentium D and Dual Core families both have various performance differences that make them unique.
History
The first member of the Pentium D family was introduced in 2005, and the first member of the Pentium Dual Core family was released in 2006.
Comparison
The Pentium D family is comprised of models that vary in clock frequency (speed), ranging from 2,667 MHz (model 805) to 4,096 MHz (model 960). The Pentium D has a much higher overall frequency than the Pentium Dual Core, having a 1,007 MHz advantage over the lowest-frequency Dual Core processor and a 267 MHz advantage over the highest-frequency Dual Core. The Pentium Dual Core ranges in frequencies that range from 1,600 MHz (model E2140) up to 3,333 MHz (model E6800). Despite a few models (E5300 and E5400), the Pentium D and Dual Core family all consist of the same socket type, Socket 775. On average, both processor families also have the same bus speed of 800 MHz. However, there are some differences, with the Dual Core family having models that also have bus speeds of 1,066 MHz and the Pentium D with a single model having a bus speed of 533 MHz. L2 cache sizes also vary between the two processor families. The Pentium D has cache sizes of 512 KB (kilobytes), 1,024 KB and 2,048 KB, and the Dual Core family has cache sizes of 2,048 KB and 4,096 KB.
Fun Fact
The Pentium D and Pentium Dual Core both have models that vary in codename (core name). The Pentium D consists of models with codenames Smithfield and Presler, and the Dual Core consists of Allendale, Wolfdale-3M and Clarkdale. The codename that each model is released with is determined by their makeup. Each codename represents a change in architecture, parts or tweaks from previous processors.
