Intel · Pentium III · 1999 · Slot 1
The Intel Pentium III 500 is a desktop processor with 1 core, released in 1999 at an MSRP of $696. 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 0.5 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 28W, the Pentium III 500 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.
Launch Pentium III (February 26, 1999). The Katmai die featured 512KB of L2 cache on a separate module running at HALF the CPU clock speed. Introduced SSE (Streaming SIMD Extensions).
