Low Power and Energy-Efficient CPUs from Intel and AMD Core2 Duo E6300 vs. X2-3800+ (ADD) and X2-4600+ (ADO)

Gaming Performance vs. Power

3DMark'05 CPU Test

Actual screenshot from 3DMark 2006

For the longest time, 3DMark's CPU test was dominated by AMD processors. The Core2 Duo/Extreme changed this picture in that the top scores are now savely in Intel's hand. Naturally, the E6300 falls further back into the crowded upper midrange of performance, arbitrarily defined here as a score between 7000 and 8000. In the same area are also found the Pentium 955XE (Presler) and several AMD processors, including the "ADD" X2-3800+

Of course, things change around again as soon as the actual processor power consumption is taken into account. For clarification: we are taking the highest power number measured towards the end of the second run of the CPU benchmark as baseline and use treat this value as sustained power draw to calculate the score/W value.

Given the extreme energy efficiency of the "ADD" X2-3800+, it is no big surprise to see it take the lead here. It is mindboggling, though to see this CPU pull ahead of everything else by a solid 20% margin to the next competitor - in this case Intel's Core2 Duo 6700. The rest of the field is more or less "also-ran"..
