The Intel Pentium III Xeon 900 2.8V was a server/workstation processor with 1 core, launched in March 2001, at an MSRP of $3692. It is part of the Pentium III Xeon lineup, using the Cascades architecture with Slot 2. To further increase overall system performance, up to four Pentium III Xeon 900 2.8V CPUs can link up in a multi-processor (SMP) configuration. Pentium III Xeon 900 2.8V has 2 MB of L2 cache and operates at 900 MHz. Intel is building the Pentium III Xeon 900 2.8V on a 180 nm production process using 140 million transistors. The multiplier is locked on Pentium III Xeon 900 2.8V, which limits its overclocking capabilities.
With a TDP of 36 W, the Pentium III Xeon 900 2.8V consumes only 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. 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.
