Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 2 threads. Mobile Pentium 4 2.40 has 512 KB of L2 cache and operates at 2.4 GHz. Intel is building the Mobile Pentium 4 2.40 on a 130 nm production process using 55 million transistors. The multiplier is locked on Mobile Pentium 4 2.40, which limits its overclocking capabilities. With a TDP of 60 W, the Mobile Pentium 4 2.40 consumes typical power levels for a modern PC. Intel's processor supports DDR1 and DDR2 memory. Neither SSE3 nor SSE4 instruction sets are supported, which will lead to problems with games not starting.
