Intel · Pentium 4 · 2001 · 478
The Intel Pentium 4 2.0 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 2 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 72W, the Pentium 4 2.0 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.
Top Willamette. The 180nm process's limits were showing — 72W TDP for 2.0 GHz was poor efficiency. The Northwood 130nm revision at the same speed was a substantial improvement.
