Test System Components
The beginning of this article will focus on introducing all of the system components, because they play an important role in energy analysis. This will also help you achieve a better understanding of the performance capabilities of a complete system.
Our complete test system platform for energy measurement.
For our energy measurements, we used the MSI K9A2 Platinum motherboard, which is based on AMD’s high-end 790FX chipset. We chose the MSI board because it has a lower power draw than comparable products from Asus or Gigabyte.
Test motherboard: MSI K9A2 Platinum with the 790FX chipset.
The BIOS 1.3 equipped motherboard is used with standard settings, which means that all on-board components, like audio and serial ports, are turned on. The test system has 2 GB of DDR2 RAM memory from A-DATA. The Vitesta module is run at DDR2 800 with a timing of CL5.0.
2 GB DDR2 memory M2OMIDG314720INC5Z from A-DATA
Our cooler is the Zalman CNPS9700 LED, used with the Fanmate 2 fan controller.
The cooler is set to maximum speed during the test, which enables our instruments to produce stable measurements.

Our system is equipped with a system cooler for the hard drive.

The are still built on the 90nm process.
The P45 will introduce the 65nm process on the chipsets.
The latest AMD Chipsets use the 55nm process.
In regards to CPUs, The Intel CPUs generally use less than the AMD CPUs.
He was simply pointing out that the CPUs lose some of the benefeit of their low power consumption due to the chipset.
For lower-end chips sitting idle, the difference in power usage of the chipsets can be significant. If you are looking at a higher-end chip under load, the power usage of the chipset becomes nominal.
Intel is not the greenest if it is less power hungry? Do they not meet RoHS standard or something?
Rohs = reduction of hazrdous substances, nothing to do with power consumption
at least one could see, if intel's "nominal" TDP's are as regular as amd's.
here we see, the phenom 95 watts DO HAVE 95 watts at maximum.
IMO the dynamic power used by the processor is a factor of frequency, voltage and probably the number of transistors. The Phenom has 2 more cores, and a much larger L3 cache. The Phenom core itself is fairly similar to the K8s, and should not exhibit that much power increase if you can match the setup of a typical X2...
I would be interested to see a chart that showed how many watts it takes to do a multi threaded task. For example, a faster core(s) finishes the job quicker then can drop to its low power state. And also on how much work can be done in a distributed computing task. This would be similar to "it takes X-watts to complete a task.”
Its grate and more economyc than cool n´quite.
HTPCs is probably hit the hardest by this, and any other system that is placed in so called computer desks that have a closed cabinet for the PC. Hot running system increases heat generation and affects home/server room temperatures which also affects the power bill. Cooler running systems also lead to quieter system cause of the decrease of cooling fans.
One Item I would also like to see tested are power consumption among motherboards. CPUs and GPUs are obvious that the higher the performance the more the power will be used, but how does it compare with motherboards.
Nice article! I would be interested to see a chart that showed how many watts it takes to do a multi threaded task. For example, a faster core(s) finishes the job quicker then can drop to its low power state. And also on how much work can be done in a distributed computing task. This would be similar to "it takes X-watts to complete a task.?
YES! Specifically, I'd like to see how much energy is used by each system if they have to do the same task for a given about of time ... like play a dvd for 2 hours.
