    Default Ubuntu 12.04 ARM Performance Becomes Very Compelling

    Phoronix: Ubuntu 12.04 ARM Performance Becomes Very Compelling

    Last week I delivered benchmarks showing how Ubuntu 12.04 is ARM-ing up for better performance with ARM-based hardware and detailed some of the plans Canonical has for this architecture going forward. While those benchmarks last week illustrated some significant performance improvements with the Ubuntu 12.04 stack -- in large part due to the switch to hard floating-point support -- the gains are not over. In fact, there are already some striking improvements if using the Texas Instruments OMAP4460 SoC as found on the PandaBoard ES.

    Enabling the hotplug governor will allow cores to be completely powered off (if on separate power planes), and frequency scaling works a bit differently as well.

    This is awesome. I'd like to see how Kubuntu and Ubuntu compare in terms of performance though.

    I was wondering how the pandaboard all in all compared to a moderately modern laptop. In this case a first generation i5 (480M):

    Yes, I know that they are not meant to be in the same performance class. I wanted to see it anyway.
    Also, the benchmarks are not ideal since I was surfing / working while running it.

    is there also a core2 8200 quad and dual tested (with an old DDR2 MB ?) in OB , that might have been a little closer ?.

    it would also be better if someone did a FULL TegraŽ 3 Quad-core CPU test with both this
    Ubuntu 12.04 and the latest and greatest
    The Linaro Kernel Tree https://wiki.linaro.org/WorkingGroups/Kernel/KernelTree
    , sure it would still loose compared to the i5 and even the i3 due to having a slower ram and subsystem on board right now if nothing else all being equal, but it is the best until A15 etc or at least a faster 1.6/8 gig dual A9 comes along, and Tegra3 prime does have NEON on board unlike the Tegra2 and is a current key device for linaro.

    i thought
    Michael was supposed to get a quad TegraŽ 3 prime in the post to test already, what happened there, didnt you follow it up
    Michael ?

    Well it's not about "losing".. It was obvious it would be much slower. But I wanted to see it in perspective.

    I think comparing it with a CULV would be maybe "fairer" on the x86 side...
