Linux vs. Windows Power Usage
Since publishing our Ubuntu power tests, where we had monitored the power consumption of the past six Ubuntu releases going back two years on a laptop, we've had repeated requests for a power comparison between Windows and different Linux distributions. Well, in this article are the first set of results from that testing. We've compared the power consumption of Microsoft Windows XP, Windows Vista, Fedora 7, and Ubuntu 7.10.
For these tests we hadn't used the Lenovo ThinkPad R52 notebook again, but had turned to an older hardware configuration. This is the same system from our Linux For Older PC Hardware article, which consisted of an Intel Pentium 4 1.46GHz (Northwood) processor, 2 x 512MB DDR-400, Western Digital 80GB 8MB cache ATA-100 hard drive, DVD-ROM, and an ASUS P4SGX-MX motherboard. This motherboard uses the SiS 650GX + 962L Chipset and has SiS Real 256 graphics.
Like our Ubuntu power testing, a SeaSonic Power Angel was used for measuring the power consumption of the system.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
