The Intel Pentium III Xeon 500 2MB was a server/workstation processor with 1 core, launched in March 1999, at an MSRP of $3692. It is part of the Pentium III Xeon lineup, using the Tanner architecture with Slot 2. To further increase overall system performance, up to four Pentium III Xeon 500 2MB CPUs can link up in a multi-processor (SMP) configuration. Pentium III Xeon 500 2MB has 2 MB of L2 cache and operates at 500 MHz. Intel is building the Pentium III Xeon 500 2MB on a unknown production process using 10 million transistors. The multiplier is locked on Pentium III Xeon 500 2MB, which limits its overclocking capabilities. With a TDP of 37 W, the Pentium III Xeon 500 2MB consumes only little energy. The highest officially supported memory speed is 100 MT/s, but with overclocking (and the right memory modules) you can go even higher. This processor lacks integrated graphics, you might need a graphics card. Many games will refuse to start on this processor due to the lack of the SSE2/SSE3/SSE4 instruction set.
