Low Power Server CPU Shoot-out

Power is on everyone's mind these days and rightfully so. The cost of operating and cooling the average server is certainly not cheap, and is on the rise year over year. The question is whether the CPU is the component under the hood that is utilizing the majority of total system power or not. The answer to that question should be clear: the CPU is just a piece of the puzzle. Memory, fans, chipset, drives, HBAs, etc. all play a role in utilizing power.

AMD is clearly the leader when it comes to performance per watt using the workloads in this article. What is interesting to note is that AMD's advantage isn't at the processor level, but instead it's related to the fact that they don't use fully buffered DIMMs. Obviously, the measurements we took of each component aren't precise - it's just about impossible to do that (at least without sophisticated equipment). However, we can safely draw the conclusion that there is a lot more to power consumption than the CPU itself.

Whoa, if I knew more about woodcrest vs current opty performance i'd probably be less/more shocked?

I think this is also another thing that is keeping AMD from falling, they are holding the server market and the low to mid grade price per performance.

AMD low end ftw.
AMD server end ftw.

They are still good at some stuff. Hopefully they will be back in the hearts of many desktop and enthusiasts.
