Surprising Power Consumption Of Ubuntu 11.04 vs. Windows 7

Filed under

Ubuntu

After recently tracking down the major Linux kernel power regression that's present for a vast number of mobile users in Fedora 15, Ubuntu 11.04, and other recent Linux distributions shipping the 2.6.38+ kernel, the sights were turned to see how the power management of Ubuntu 11.04 compares to that of Windows 7 Professional Service Pack 1. In this article are the power consumption results of Ubuntu 11.04 compared directly to Windows 7 Professional 1 on several different systems with distinct notebook and desktop / workstation configurations.

For all testing, the Watts Up Pro power meter was used with its USB interfacing to the Phoronix Test Suite software for automatic monitoring. This monitoring was done by an independent system the entire time to ensure that there weren't any Windows/Linux software monitoring differences as the power meter was attached to each system's power supply.

The systems that where we looked at the Ubuntu 11.04 x86_64 vs. Windows 7 Professional Service Pack 1 x64 included:

* Lenovo ThinkPad T61: Intel Core 2 Duo T9300, Hitachi 100GB HTS72201 SATA HDD, Intel PM965 + ICH8M-E, 4GB DDR3, NVIDIA Quadro NVS 140M 512MB.

* Gulftown: Intel Core i7 990X, ASRock X58 SuperComputer, 3GB DDR3, 320GB Seagate ST3320620AS SATA HDD, NVIDIA GeForce 9800GTX.

* Dual Opteron: 2 x AMD Opteron 2384 Quad-Core CPUs, Tyan S2932 motherboard, 160GB Western Digital WD1600YS-01S SATA HDD, 4GB ECC Registered DDR2, ATI FirePro V8700.

* Phenom II: AMD Phenom II X3 710, MSI 890GXM-G65, Seagate 250GB ST250310AS SATA HDD, 4GB DDR3, AMD Radeon HD 4650.

Oh noes - a missing link

No Linky. Unless the "rest here" means "rest" and not "rest".

English is so confusing.

Bang & Olufsen’s RPi add-on brings digital life to old speakers

B&O and HiFiBerry have launched an open source, DIY “Beocreate 4” add-on for the Raspberry Pi that turns vintage speakers into digitally amplified, wireless-enabled smart speakers with the help of a 180-Watt 4-channel amplifier, a DSP, and a DAC. Bang & Olufsen has collaborated with HiFiBerry to create the open source, $189 Beocreate 4 channel amplifier kit. The 180 x 140 x 30mm DSP/DAC/amplifier board pairs with your BYO Raspberry Pi 3 with a goal of upcycling vintage passive speakers. Read more

The makers of the Gemini PDA plan to begin shipping the first units of their handheld computer to their crowdfunding campaign backers any day now. And while the folks at Planet Computer have been calling the Gemini PDA a dual OS device (with Android and Linux support) from the get go, it turns out the first units will actually just ship with Android.

  • Best Web Browser
    When the Firefox team released Quantum in November 2017, they boasted it was "over twice as fast as Firefox from 6 months ago", and Linux Journal readers generally agreed, going as far as to name it their favorite web browser. A direct response to Google Chrome, Firefox Quantum also boasts decreased RAM usage and a more streamlined user interface.

    A “screenshot” is created when you capture what’s on your computer screen, so you can save it as a reference, put it in a document, or send it as an image file for others to see exactly what you see.
  • What Happens when you Contribute, revisited
    I sat down to write a post about my students' experiences this term contributing to open source, and apparently I've written this before (and almost exactly a year ago to the day!) The thing about teaching is that it's cyclic, so you'll have to forgive me as I give a similar lecture here today. I'm teaching two classes on open source development right now, two sections in an introductory course, and another two in a follow-up intermediate course. The students are just starting to get some releases submitted, and I've been going through their blogs, pull requests, videos (apparently this generation likes making videos, which is something new for me), tweets, and the like. I learn a lot from my students, and I wanted to share some of what I'm seeing.
