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.

QNX 7 Can Be Fitted With A Qt5 Desktop

  • QNX 7 Can Be Fitted With A Qt5 Desktop
    While QNX remains targeted as an operating system for mobile/embedded solutions, a BlackBerry developer in his spare time has fitted QNX 7 with a Qt5 desktop. QNX 6 and prior had a desktop option, but was removed in QNX 7, which was released this past March. QNX 7.0 also brought support for 64-bit (and maintaining 32-bit) Intel x86 and ARM platforms along with C++14 support. For those wanting to experiment with QNX 7, a BlackBerry kernel developer has been working on making this operating system more desktop friendly.
  • Building a BlackBerry QNX 7 Desktop
    Having Qt allowed me to port one of my favourite applications, SpeedCrunch. It was a simple matter of running ‘qmake’ followed by ‘make’. Next, I ported the QTermWidget library so that I could have terminal windows.

  • State of Sway April 2017
    Development on Sway continues. I thought we would have slowed down a lot more by now, but every release still comes with new features - Sway 0.12 added redshift support and binary space partitioning layouts. Sway 0.13.0 is coming soon and includes, among other things, nvidia proprietary driver support. We already have some interesting features slated for Sway 0.14.0, too! Today Sway has 21,446 lines of C (and 4,261 lines of header files) written by 81 authors across 2,263 commits. These were written through 653 pull requests and 529 issues. Sway packages are available today in the official repos of pretty much every distribution except for Debian derivatives, and a PPA is available for those guys.

  • Surface revenue does a U-boat, and dives

    Revenue generated by Microsoft's Surface hardware during the March quarter was down 26% from the same period the year before, the company said yesterday as it briefed Wall Street.

    For the quarter, Surface produced $831 million, some $285 million less than the March quarter of 2016, for the largest year-over-year dollar decline ever.

  • Acer said to me: "do not use our products with Linux. Find another manufacturer"
    Last year, I bought an Acer notebook and it came with Windows 10. As I didn't want spyware neither bloatware, I got Linux installed and asked for a refund of the OEM license. After a little of talking, they were wanting to charge me US$100 (to remove the license, which I already had wiped, as I got FDE Linux installed) to refund US$70 of the OEM license. This year, wondering to buy a new Acer notebook, I asked them again if they would refund me the OEM license without all the hassle (as they did pay me the US$70, without me having to pay the US$100).
