Surprising Power Consumption Of Ubuntu 11.04 vs. Windows 7
Looking at the lines of power consumption for the Nexuiz testing, the power consumption here was close too.
The Windows 7 driver, however, was slightly faster than the binary blob in Ubuntu 11.04 when running the Nexuiz game at 1920 x 1080. Overall, Ubuntu 11.04 faired very well against Microsoft Windows 7 Pro SP1 in terms of power consumption for this very fast Intel desktop.
