    My new Triumph just scored 1660 on Quadrant. If I'm calculating correctly, that's about 53% faster than my quasi-stable Optimus V when overclocked.

    The Optimus V on Quadrant scored almost 1087 when overclocked from 600 to 864 Mhz, with governor set to "interactive" on AOSP's ROM.

    So what can the Triumph do when overclocked? Using Gingerbreak, it's now rooted. So do we really need a new ROM, or at least a kernel to overclock it? Battery life was ok, the whole day, with lots of wifi, GPS, BT, 3G, etc. It'll be worth it. Where can I get / try the kernel?

    What I'm wondering is if I read that the same processor of the Triumph was either overclocked to 2000 Mhz, or was it a quadrant score of 2000.

    Yes, a new overclocking kernel will be required. Hopefully some developers will pick up the phone and start working on kernels and roms. This thing seems PERFECT for hacking since it is apparently not locked down at all. Permanant root is easily achieved, booting into the bootloader allows you to simply copy the boot image onto/off of the device by plugging into a PC. Can't ask for much more :)

    so has the bootloader been confirmed as unlocked and unencrypted?

    Why would you want to overclock this thing? The battery is bad enough as it is! I want to underclock it to around 800Mhz and see if that makes a big difference in batt life.

    Some have done testing on the OV and found that overclocking can actually help (or at least not hurt) battery life. Although it makes the processor run faster, it doesn't have to stay running as long so it kind of balances out. I'm hoping that holds true for the MT as well.

    I just got a 1965 on Quadrant using the deadline scheduler and performance govenor. But with overclocking and undervolting(through a custom kernel) we can get better performance and better battery life!

    Race to Idle


    Current processors are quite good about saving power when idle; so much so that many show a behavior around power saving that surprises many people.

    This behavior, called race-to-idle, is best explained with a simplified example:

    Lets take a typical commercially available processor that consumes 34 Watts when running at full speed, and 24 Watts when running at half speed and 1 Watts when idle (using frequency and voltage scaling using P-states).

    On this processor, we're decoding one second of a MP3 file or some HDTV media every second. This decoding takes 0.5 seconds at half speed, and, consequently, 0.25 seconds at full speed.

    The energy consumption for one second is

    Half speed: 0.5s * 24W + 0.5s * 1W = 12.5 Joules
    Full speed: 0.25s * 34W + 0.75s * 1W = 9.25 Joules
    Even though the above example is simplified from reality, the same paradigm tends to hold for real systems: It's generally better to run as fast as you can so that you can be idle longer.
