AMD Socket-F Opteron vs. Intel Woodcrest@ 2006/12/18
Of course any loyal Intel fan is going to cry foul, but rest assured we checked to see that there was no foul play here. The BIOS settings were configured as identically as possible, the fans were all running inside the case, etc. We've wanted to do this kind of comparison for awhile but lacked the equipment in the lab to create two identical systems. As we alluded to above, the only component that wasn't the same was the processor cooling. Intel's thermal design for most Xeon systems is an air duct that is fed by a hefty 6" fan on one side and vented out the rear of the case (see pictures on the next page). This usually produces a system that sounds like a miniature wind tunnel, at least for the server versions. There are of course a few other differences, but most of those relate to the platform: registered DDR2 vs. FB-DIMMs, different chipsets, and different motherboards were used, but that will always be the case.
