| Intel's P4 820D and 670 More Power to Duallies | |

(Review by MS September 3, 2005) |
| P4-670 |
Raw Power
Given the fact that most systems are either idle or else run under full load for most of the time, these two scenarios are the most important for an overall evaluation of the economic performance of a given processor. Keep in mind also that anything in between would be terribly difficult to quantify
Regardless of power management or not, the P4 is a power hog and, moreover, our power measurements on the P4 670 remained at a constant level, which confirms our suspicions based on PC Wizard 2005 that there is no EIST-based clock reduction under idle conditions in the test configuration used. Keep in mine that the mainboard is Intel Original.
Prime95 used in either single instance or up to 4 parallel versions running on the different physical and logical cores. Overall the power consumption of the P4 670 using a single or two instances of Prime95 is way beyond that of the 820 under similar conditions. Note that there is little difference between hot and cold on the P4's whereas the AMD CPUs show a more or less noticeable temperature derating of the overall power efficiency
