Principled Technologies, Inc.: Energy consumption of seven Intel chipset motherboards

Test results

Figure 5 presents energy consumption measurements (the median of three or five runs for each test) for the systems with the seven motherboard models. (In the event of a tie, we chose the run with the higher energy consumption. If the energy consumption score was also tied, we then chose the first run we executed with those scores.) Because energy consumption results represent the energy the systems used when completing the workload, lower is better. We used the Extech Instruments 380803 Power Analyzer to gauge energy consumption. The Extech Power Analyzer is an external unit that connects to a host computer through a RS-232 communications cable. The device also has an AC power cable that powers the system under test. We used the Extech Power Analyzer to monitor the average AC energy consumption of each system while running the four custom tests. We then multiplied the Extechs average AC power score by the time the workload took to complete to calculate the Workload Energy Consumption (WEC) in watt-seconds. We divided the WEC watt-seconds score by 3,600 (the number of seconds in an hour) to calculate the WEC Watt-hours we report below. The Idle and Web browsing tests ran for a fixed amount of time (five minutes) while the other tests ran as long as necessary to complete the task.

Test methodology

This section discusses some differences in the configurations of the test systems, and details the methodologies we followed in testing them. We ran the tests three or five times, and report the median of those runs.

Configurations

PT purchased and built each system as identical as possible with the only difference being the motherboards. Each system consisted of: Intel Core 2 Duo Processor E8600 (3.33GHz, 1333MHz FSB, 6MB L2 Cache). (Note that the Asus P5BVM SE motherboard would only run the Intel Core 2 Duo E8600 processor at 2.66GHz with a FSB of 1066MHz) Corsair XMS2 2GB 240-pin DDR2 PC2-6400 CL=5 Seagate ST3320620AS Barracuda 320 NCQ SATA2 7200RPM Lite-On DH-16D3S SATA DVD-ROM Linkworld 536-09-c2228u ATX Mid Tower Computer Case with 430W power supply For detailed system configurations, see Appendix A.

Select the external hard disk in the copy image to drop-down box, name the file BASE, and click Save. At the Compress Image dialog, select High. At the Proceed dialog, select Yes. When the ghost image is complete, click OK, and exit Ghost. Power down the computer. Disconnect the USB hard disk. Reboot the computer.
Extech Power Analyzer setup and test procedure
We did the following to set up the Extech Power Analyzer and software: 1. Power off each computer under test. 2. Connect the power cord from the computer under test to the Power Analyzers output load power outlet. 3. Plug the power cord from the Power Analyzers input voltage connection into a power outlet. 4. Connect a separate host computer to the Power Analyzer using an RS-232 cable. This computer will monitor and collect the power measurement data. 5. Turn on the Extech Power Analyzer by pressing the green On/Off button. 6. Turn on the host computer. 7. Insert the Extech software installation CD into the host computer, and install the software as follows: a. Using Windows Explorer, browse to the Extech Power Analyzer installation CD, and click on the Setup.exe. b. At the Welcome to the Power Analyzer screen, click OK. c. At the installation screen, leave the default installation directory, and click the icon button to begin installation. d. At the Setup has completed successfully screen, click OK. 8. Launch the Extech Power Analyzer software by clicking Start All Programs Power Analyzer. 9. At the Select COM port dialog, click OK. 10. From the top menu, select Option COM. Select COM1. 11. Exit the Extech Power Analyzer software. We did the following to measure energy consumption during a test: 1. Power on the computer under test, and make sure you have prepped it to run a test. 2. On the host computer, launch the Extech Power Analyzer software by going to Start All Programs Power Analyzer. 3. From the top menu, click Option Sample Rate. Type 1.0, and click OK. 4. From the top menu, click File Name. 5. In the Name field, type a name that appropriately describes the platform and configuration, and click OK. 6. To begin recording power, click File Start Recording Now (Auto) at the same time you start a test. 7. To stop recording power, click File End Recording at the same time you stop a test. To view the power measurement data, double-click on the My Computer desktop icon and select the C: drive Program Files Power Analyzer. When the program launches, select the test name selected earlier, and double-click that file name. To open the file, select Excel as the program for viewing the data. This is the file you will use to calculate the average power usage. We calculate average power usage by doing the following: 1. Use Windows Explorer to locate the log file. By default, Windows saves the log file in C:\Program Files\Power Analyzer. 2. Open the log file with Microsoft Excel. 3. Insert a column by right-clicking on column E, and clicking Insert. 4. In cell E1, type =value(left(D1,7)), and press Enter.

5. Scroll down to the last row in column E, and press Ctrl + Shift + Up. This should select the entire E column. 6. Press Ctrl + D to fill in column E. 7. Select cell A1, and press Ctrl + F. 8. In the Find What Field, type olw, and click Find Next. This will find any outliers that may have occurred during the test. 9. Delete any row that produced an outlier. 10. In an empty cell, type =average(e:e), and press Enter. This is the Average Power Draw in Watts.
