Intel · Pentium 4 · 2004 · 478
The Intel Pentium 4 HT 3.40 is a desktop processor with 1 core, released in 2004 at an MSRP of $637. It is part of the Pentium 4 lineup, using the Pentium 4 platform, and fits the 478 socket. Internally, it is built on the "Northwood" 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 3.4 GHz. Intel manufactures the "Northwood" silicon on a 130nm 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 memory. With a TDP of 89W, the Pentium 4 HT 3.40 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 512KB of L2 cache. There is no L3 cache on this processor.
Top Northwood HT. 800 MHz FSB. The Prescott 90nm generation launched around this time with mixed results — higher clocks but significantly higher TDP.
