    Phoronix: Radeon Driver Power Management Has Room For Improvement

    Today on Phoronix are not only new benchmarks of the proprietary Catalyst graphics driver compared to the open-source Radeon Linux driver alternative when looking at the OpenGL frame-rates, but also metrics on a number of other fronts. In this article is a graphics driver comparison when looking at the system power consumption, GPU operating temperature, and CPU usage too. The results are quite interesting and not commonly looked at on Phoronix or by users.

    Code:
    default engine clock: 800000 kHz
    current engine clock: 796500 kHz
    default memory clock: 700000 kHz
    current memory clock: 693000 kHz
    voltage: 1200 mV
    PCIE lanes: 16
    Code:
    sensors:
    
    radeon-pci-0200
    Adapter: PCI adapter
    temp1:       +82.0 C
    On fglrx everything works.
    Open bug on freedesktop please.

    Yes, maybe. But I just plug that 9? thing in PC socket and it can show wattage, peak wattage, power efficiency etc. And to test if its showing right, plug 40w light bulb in it or something similar.. I mean, of course maybe wattsup shows more precisely and can report back the consumption to the machine, to use it in scripts etc. But for random drain check the basic 9? thing is more than enough. Is in every supermarket.

    Yes, I will. Unfortunately I have a long week ahead, hopefully I will be able to report it next week end.

    Where can I buy it? Is there anyone else in Europe interest to buy it?

    Thanks for reporting, dynpm is hard flawed according to Michael tests as well.
