Pentium 4-M 2.20 has 512 KB of L2 cache and operates at 2.2 GHz. Intel is making the Pentium 4-M 2.20 on a 130 nm production node using 55 million transistors. The multiplier is locked on Pentium 4-M 2.20, which limits its overclocking potential. With a TDP of 35 W, the Pentium 4-M 2.20 consumes only little energy. 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.
