Power Consumption

Since power consumption is a big deal these days, we ran some simple power consumption tests on our test beds. To measure idle usage, we ran the system at idle for one hour on the desktop with no screen saver and took the measurement. For load measurements, Cinebench R10 was run on all cores to make sure each and every processor was at 100% load. The Blu-Ray playback numbers were taken while playing the movie Star Trek from the Blu-Ray. All numbers were taken with both notebooks in 'high performance' battery mode, so these are the highest numbers you are likely to see.

Power Consumption Results

Results: The chart might look a bit messy, but it is because not all the notebooks had Blu-ray players and because we added gaming power consumptions results. The gaming tests were added as we wanted to see how power hungry the new Sandy Bridge core is when pushed with a DX10 gaming title. As you can see, when running Resident Evil 5 the Sandy Bridge processor consumed less power than when running Cinebench R10.5.  This was interesting as all the other laptops used more power during gaming. Blu-ray playback power consumption is very low, which means the battery should last a whole movie!
