No Enhanced Halt State, Thermal Monitoring 2 Or SpeedStep
Even though the new processors are clearly more efficient and offer lower power consumption level, Intel seems to have some troubles to sort out. None of the Pentium 4 or Pentium D 65 nm chips shipped today support the Enhanced Halt State C1E, Thermal Monitoring 2 or SpeedStep. Enhanced Halt State stops the processor operation to reduce thermal levels, Thermal Monitoring 2 performs a dynamic throttling function and SpeedStep can reduce core clock speeds down to 2.8 GHz with BIOS and operating system support whenever the system runs idle.
According to an Intel spokesman, these features will be added in the second quarter of 2006. You can use the Intel Processor finder to determine which chips support the full feature set: http://processorfinder.intel.com.

It is interesting to see that Intel stops at 3.6 GHz for the 6x1 single-core Pentium 4 processors. From a technical point of view, all the samples that went through our test labs were absolutely capable of running at more than 4 GHz without water cooling. As a result we're pretty sure that Intel could ship 3.8 and 4.0 GHz parts if it wanted. However, we have to agree that an entry level dual core is the better choice for most multimedia users today.

For dual cores, Intel was able to speed up the clock speed from 3.2 (Pentium D 840) to 3.4 GHz (Pentium D 950). In combination with the 900's larger L2 cache, the new top model works a bit faster than the old one.
