13 Facts About Pentium D

However, the Pentium D did not offer significant upgrades in design, still resulting in relatively high power consumption.

The Pentium D line was removed from the official price lists on July 13, 2010.

However, in multitasking environments such as BSD, Linux, Microsoft Windows operating systems, other processes are often running at the same time; if they require significant CPU time, each core of the Pentium D branded processor can handle different programs, improving overall processing speed over its single-core Pentium 4 counterpart.

On May 26, 2005, Intel launched the mainstream Pentium D branded processor lineup with initial clock speeds of 2.

All Pentium D processors supported Intel 64, XD Bit, and were manufactured for the LGA 775 form factor.

The only motherboards guaranteed to work with the Pentium D branded CPUs were those based on the 945-, 955-, 965- and 975-series Intel chipsets, as well as the nForce 4 SLI Intel Edition and ATI Radeon Xpress.

The Pentium D 820 did not work with the nForce 4 SLI Intel Edition chipset due to some power design issues, though they were rectified in the X16 version.

Week after its launch, Intel officially denied a report in Computerworld Today Australia that the Pentium D branded CPUs included "secret" digital rights management features in their hardware that could be utilized by Microsoft Windows and other operating systems, but was not publicly disclosed.

The processor was based on the dual-core Pentium D branded Smithfield, but with Hyper-threading enabled, thus any operating system saw four logical processors.

Pentium Extreme Edition based on the dual-core Pentium D branded Presler was introduced as the 955 model, at 3.

Pentium D brand was merged with the Pentium 4 brand and succeeded on July 27, 2006, by the Core 2 branded line of processors with the Core microarchitecture released as dual- and quad-core processors branded Duo, Quad, and Extreme.

Also, while the Athlon 64 X2 inherited mature multi-core control logic from the multi-core Opteron, the Pentium D was seemingly rushed to production and essentially consisted of two CPUs in the same package.

Indeed, shortly after the launch of the mainstream Pentium D branded processors and the Athlon 64 X2 (31 May 2005), a consensus arose that AMD's implementation of multi-core was superior to that of the Pentium D As a result of this and other factors, AMD surpassed Intel in desktop PC sales at US retail stores for a period of time, although Intel retained overall market leadership because of its exclusive relationships with direct sellers such as Dell.
