The Intel Pentium III 1133 was a desktop processor with 1 core, launched in July 2000, at an MSRP of $990. 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 1133 CPUs can work together in a multi-processor (SMP) configuration. Pentium III 1133 has 256 KB of L2 cache and operates at 1133 MHz. Intel is making the Pentium III 1133 on a 180 nm production node using 28 million transistors. The multiplier is locked on Pentium III 1133, which limits its overclocking potential.
With a TDP of 29 W, the Pentium III 1133 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. 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.
