The Intel Pentium Extreme Edition 955 is a desktop processor with 2 cores, released in 2005 at an MSRP of $999. It is part of the Pentium D lineup, using the Pentium D platform, and fits the LGA775 socket. Internally, it is built on the "Presler" architecture. Thanks to Intel Hyper-Threading, each core can handle two instruction streams simultaneously, yielding a total of 4 threads for improved parallelism. It operates at a fixed 3.46 GHz. Intel manufactures the "Presler" silicon on a 65nm process node. The multiplier is unlocked, making overclocking straightforward. This processor supports DDR2 memory. With a TDP of 130W, the Pentium Extreme Edition 955 sits in a typical power envelope for a modern desktop CPU. This processor has no integrated graphics — a discrete GPU is required. The cache hierarchy consists of 16KB/core of L1 and 2MB/core of L2 cache. There is no L3 cache on this processor.
Presler 65nm Extreme Edition — upgraded to 2MB L2 per core vs 1MB on the Smithfield 840. HT enabled giving 4 threads. 1066 MHz FSB.
