The Intel Pentium III-S 1266 is a desktop processor with 1 core, released in 2001 at an MSRP of $340. It is part of the Pentium III lineup, using the Pentium III platform, and fits the 370 socket. Internally, it is built on the "Tualatin" architecture. It operates at a fixed 1.266 GHz. Intel manufactures the "Tualatin" silicon on a 130nm 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 32W, the Pentium III-S 1266 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.
Tualatin -S variant, 512KB on-die L2 at full speed. 133 MHz FSB.
