The Pentium Extreme Edition (codenamed Smithfield and Presler ) is one of Intel introduced on 18 April 2005 dual-core - microprocessor based on the NetBurst architecture. The Pentium Extreme Edition architecture is identical to the architecture of the respective Pentium D series (8xx ( Smithfield ) and 9xx ( Presler )). The main difference to the previously presented Pentium D processors is that the Hyper-Threading function is enabled on Pentium Extreme Edition processors . The processor can execute up to four threads at the same time, since there is another virtual core for each physical processor core. The Pentium Extreme Edition requires Intel's high-end chipsets 955X and 975X with socket 775 .

The Pentium Extreme Edition stands in the tradition of the Pentium 4 Extreme Edition . With the new naming scheme introduced at the same time as the dual-core processors, however, the “4” was dropped from the product description.

The first model presented ( Pentium Extreme Edition 840 ) has a clock frequency of 3.2  GHz and 1  MiB Level2 cache per physically present processor core. In addition to the Hyper-Threading technology, the functions also differ in the activated multiplier, which significantly simplifies overclocking the processor.

At the end of 2005, the next model, the Pentium Extreme Edition 955, came onto the market, which was clocked a little higher at 3.46 GHz, but was manufactured with a new processor core in 65 nm. Due to the now smaller die area, the L2 cache per core could be doubled, and as with the Pentium D 9xx, the Intel Virtualization Technology was activated and, in contrast to the Pentium D, the FSB increased to 266 MHz (quad-pumped, FSB 1066).
