Intel Corp. started recently started revenue shipments of its dual-core Intel Pentium D processors made using 65nm process technology and no surprise that some of those chips “leaked” to the hands of reviewers. AnandTech has managed to get some of the upcoming chips, measured their power consumption and investigated overclock-ability.

Intel’s upcoming Presler and Cedar Mill processors are likely to be among the last NetBurst-based chips with two and one processing engines respectively. It is projected that the aforementioned chips are derivatives of Smithfield and Prescott central processing units produced using 65nm process technology with minimal architectural changes.

“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 ,” concludes AnandTech .

“The reduction in power consumption is impressive, but still not enough to give Intel an advantage over AMD, which makes things better, but hardly fixes the problem in our opinion. Unfortunately, we will have to wait for Intel’s next-generation processors for a true competitor to AMD's low power Athlon 64s,” writes AnandTech .
