Pentium III 1133 has 256 KB of L2 cache and operates at 1133 MHz. Intel is making the Pentium III 1133 on a 130 nm production node using 44 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. 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.
