Intel · Pentium D · 2005 · LGA775
The Intel Pentium D 805 is a desktop processor with 2 cores, released in 2005 at an MSRP of $133. It is part of the Pentium D lineup, using the Pentium D platform, and fits the LGA775 socket. Internally, it is built on the "Smithfield" architecture. It operates at a fixed 2.66 GHz. Intel manufactures the "Smithfield" silicon on a 90nm process node. Its multiplier is locked, so any overclocking has to come from raising the base clock rather than the multiplier. This processor supports DDR2 memory. With a TDP of 95W, the Pentium D 805 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 1MB/core of L2 cache. There is no L3 cache on this processor.
Budget Smithfield — the entry-level dual-core Pentium D. 95W TDP vs 130W on higher models. No Hyper-Threading (unlike the Pentium Extreme Edition 840). Popular for budget dual-core builds.
