Intel · Pentium III · 1999 · Socket 370
The Intel Pentium III 550E is a desktop processor with 1 core, released in 1999 at an MSRP of N/A. It is part of the Pentium III lineup, using the Pentium III platform, and fits the Socket 370 socket. Internally, it is built on the "Coppermine" architecture. It operates at a fixed 0.55 GHz. Intel manufactures the "Coppermine" 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 SDRAM memory. With a TDP of 15W, the Pentium III 550E is an efficient chip suitable for modest cooling solutions. This processor has no integrated graphics — a discrete GPU is required. The cache hierarchy consists of 32KB of L1 and 256KB of L2 cache. There is no L3 cache on this processor.
