    Intel CoreDuo 2Ghz iMac vs DP 1.8 G5

    Replaced my DP 1.8 G5 with a CoreDuo 2.0Ghz iMac this past week.

    The DP 1.8 G5 did ~60g nodes/sec

    The CoreDuo 2.0 does ~ 56.7g nodes/sec

    Advantage: Still PPC

    The iMac gets to around 169F. A 2.0 G5 iMac I had spiked at 176F during OGR. iMac's are definately not set up for optimal cooling.

    Don't think I'll be running OGR on this thing.

    I would be interested in knowing what the difference in timings are for RC-5, if you have the time.

    Beyond,

    I have the G5 disconnected for shipping but will do before it happens.

    I tested on the 2Ghz CoreDuo and got 10,758,xxx keys/sec.

    Does that sound right?

    1.47GHz mac mini does 300 blocks per day on RC5, 3T nodes on OGR.

    I did a test for Beyond. i don't do RC-5. How does keys/sec translate to blocks? Or give me a measurement in keys/sec of your mini.

    According to Bok's stats 300 blocks = 15.00 Mkeys/sec

    That's a G4 mini no? That prolly explains it. Or the auto detection routine didn't select the best core for the CoreDuo.

    Thanks for testing.

    The rule of thumb on dnet is 10:1 ratio OGR:RC5 on AMD and somewhat less on Intel in the past. Was not sure if it still held true with the newer processors.

    My Core 2 Duo at 3.6Ghz is doing 93 Mnodes/sec with core #2. With core #3 it hits ~110 Mnodes/sec but crashes. Hopefully it will be fixed in the next beta.

    Advantage PC!

    Now to get my hands on Quad Core and overclock it!
    I'm having fun!!! I'm just not sure if it's net fun or gross fun.

    huh, I never consider crunching on the mac mini in one corner or the iMac in the other. Might be time to see what the PPCs will do. I better dust em first!
