Intel · Pentium III · 1999 · Slot 1
The Intel Pentium III 550 is a desktop processor with 1 core, released in 1999 at an MSRP of $849. It is part of the Pentium III lineup, using the Pentium III platform, and fits the Slot 1 socket. Internally, it is built on the "Katmai" architecture. It operates at a fixed 0.55 GHz. Intel manufactures the "Katmai" silicon on a 250nm 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 30W, the Pentium III 550 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 512KB of L2 cache. There is no L3 cache on this processor.
