The Intel Pentium III 500E was a desktop processor with 1 core, launched in October 1999, at an MSRP of $239. It is part of the Pentium III lineup, using the Coppermine architecture with Socket 370. To further increase overall system performance, up to two Pentium III 500E CPUs can link up in a multi-processor (SMP) configuration. Pentium III 500E has 256 KB of L2 cache and operates at 500 MHz. Intel is building the Pentium III 500E on a 180 nm production process using 28 million transistors. The multiplier is locked on Pentium III 500E, which limits its overclocking capabilities.
With a TDP of 13 W, the Pentium III 500E consumes very little energy. The highest officially supported memory speed is 133 MT/s, but with overclocking (and the right memory modules) you can go even higher. Actual memory technology support depends on the chosen motherboard, because the memory controller is located on the motherboard (not in the processor). Although the processor doesn't come with integrated graphics, certain motherboards with compatible chipsets can provide this capability.
Many games will refuse to start on this processor due to the lack of the SSE2/SSE3/SSE4 instruction set.
