The highest speed of Intel’s Pentium D processors currently in the market still remain below 4GHz. In very near future, we will see dual-core Intel Pentium D processors using 65nm process technology available as Intel is now ready to ship them.

Well, some hardware reviewers have already received some of the latest chips to measure their power consumption and investigate its overclock-ability, AnandTech is one of them. According to them :-

Quoted:
“The new cores do definitely overclock much better than their predecessors, and they will allow any serious overclocker to reach speeds greater than 4.0GHz effortlessly. Most exciting to us was the 4.25GHz overclock that we saw on Presler, as a 4.25GHz Pentium D will truly be a formidable opponent to AMD’s Athlon 64 X2. Cedar Mill offered reasonable overclocking headroom as well, but we would have liked to see a 5.0GHz overclock on standard air cooling, given that reaching 4.0GHz is possible today on Prescott.”

However, despite the impressive reduction in power consumption, Pentium D still does not give Intel the advantage to outperform AMD.
