Intel · Pentium 4 · 2001 · 478
The Intel Pentium 4 1.8 is a desktop processor with 1 core, released in 2001 at an MSRP of $562. It is part of the Pentium 4 lineup, using the Pentium 4 platform, and fits the 478 socket. Internally, it is built on the "Willamette" architecture. It operates at a fixed 1.8 GHz. Intel manufactures the "Willamette" silicon on a 180nm 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 67W, the Pentium 4 1.8 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 256KB of L2 cache. There is no L3 cache on this processor.
Willamette on Socket 478 — the more affordable and accessible platform that replaced Socket 423. DDR memory support via the Intel 845 chipset made this generation far more practical to build.
