Pentium D Dual Core Vs. Pentium Core 2 Duo

The microprocessor is a crucial component of your computer.

The Pentium D Dual Cores and the Core 2 Duo processors are 64-bit, dual-core microprocessors from Intel, with some of each made for laptops and others for desktops. Intel produced 14 D Dual Core processors and 24 Core 2 Duo processors.

Speeds

The front-side bus speed of the D Dual Cores range from 533 megahertz (MHz) to 800 MHz; the Core 2 Duo speeds range from 800 MHz to 1333 MHz. D Dual Cores range from 2.66 gigahertz (GHz) to 3.6 GHz in processing speed, and the Core 2 Duos range from 1.8 GHz to 3.33 GHz.

Power

The maximum power draw of the D Dual Cores is 95 watts to 130 watts, and each of the Core 2 Duos draw 65 watts. Some D Dual Cores have 65 nanometer (nm) technology, and others have 90 nm, while the Core 2 Duos are 45 nm- and 65 nm. The D Dual Cores are intended for PLGA775 socket types, as are some Core 2 Duos. Others are intended for the LGA775 socket type.

Cache

Some of both processor types use Intel virtualization technology, which offers increased security and hardware efficiency. They all have two cores and two threads. The D Dual Cores have two megabytes (MB) or four MB of cache, and the Core 2 Duos have 2 MB, 3 MB, 4 MB or 6 MB of cache.
