The Intel Pentium 4 2.40 was a desktop processor with 1 core, launched in March 2004. It is part of the Pentium 4 lineup, using the Prescott architecture with Socket 478. Pentium 4 2.40 has 1 MB of L2 cache and operates at 2.4 GHz. Intel is making the Pentium 4 2.40 on a 90 nm production node using 125 million transistors. The multiplier is locked on Pentium 4 2.40, which limits its overclocking potential.
With a TDP of 110 W, the Pentium 4 2.40 consumes a lot of power, so good cooling is definitely needed. Intel's processor supports DDR1 and DDR2 memory. Although the processor doesn't come with integrated graphics, certain motherboards with compatible chipsets can provide this capability.
The SSE4 instruction set is not supported, which can cause problems with modern games, as they require that capability.
