Intel · Pentium 4 · 2005 · Socket 478/775
The Intel Pentium 4 HT 531 is a desktop processor with 1 core, released in 2005 at an MSRP of N/A. It is part of the Pentium 4 lineup, using the Pentium 4 platform, and fits the Socket 478/775 socket. Internally, it is built on the "Prescott" architecture. Thanks to Intel Hyper-Threading, each core can handle two instruction streams simultaneously, yielding a total of 2 threads for improved parallelism. It operates at a fixed 3 GHz. Intel manufactures the "Prescott" 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 DDR/DDR2 memory. With a TDP of 84W, the Pentium 4 HT 531 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 of L1 and 1MB of L2 cache. There is no L3 cache on this processor.
