Intel · Pentium III · 2000 · 370
The Intel Pentium III 866 is a desktop processor with 1 core, released in 2000 at an MSRP of $290. It is part of the Pentium III lineup, using the Pentium III platform, and fits the 370 socket. Internally, it is built on the "Coppermine" architecture. It operates at a fixed 0.866 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 27W, the Pentium III 866 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.
Coppermine, 133 MHz FSB. Available in both Slot 1 and Socket 370.
