Pentium D#Smithfield XE

The Pentium Extreme Edition ( codename Smithfield and Presler ) is a term introduced by Intel on 18 April 2005 dual-core microprocessor based on the NetBurst architecture. The Pentium Extreme Edition architecture is the architecture of the respective Pentium D series ( 8xx ( Smithfield ) and 9xx ( Presler ) ) are identical. The main difference to the previously presented Pentium D processors is that in Pentium Extreme Edition processors supporting Hyper- Threading feature is enabled. Thus, the processor can execute up to four threads because on each physical processor core comes another virtual core. The Pentium Extreme Edition requires Intel's high-end chipsets 955X and 975X with Socket 775

The Pentium Extreme Edition continues the tradition of the Pentium 4 Extreme Edition. With the new naming scheme introduced simultaneously with the dual-core processors, however, fell off the "4" in the product description.

The first model presented (Pentium Extreme Edition 840 ) has a clock frequency of 3.2 GHz, and 1 MiB Level 2 cache per processor core physical '. The functions differ in addition to the Hyper -Threading technology is still through the unlocked multiplier which makes overclocking the processor significantly.

The end of 2005 came with the Pentium Extreme Edition 955, the next model on the market, which has been clocked at 3.46 GHz slightly higher, but is made with a new processor core 65 nm. By now smaller die area of the L2 cache was doubled per core, also has the Intel Virtualization Technology enabled as with the Pentium D 9xx and, unlike the Pentium D FSB to 266 MHz (quad pumped FSB 1066) increased.
