Instead Intel is going to launch a brand new CPU named Merom, for all computers somwhere in 2007.
Merom will use a 0.65nm production process and will be based on Intel's Pentium M processor architecture. There will be Merom processors with different amounts of cache for each market.
Intel’s Netburst architecture that supports the Pentium 4 processors is likely to be phased out from the PC market when the Merom comes online, according to the sources. Under Netburst, Intel’s Prescott processors have been constantly haunted by problems such as heat dissipation and high power consumption.Source: DigiTimes
