How much power will Yonah's consume compared to G4's?

    With all this talk about the Yonah's going into Macs I was wondering how big the benefit there would be with battery life with the Low-votage and "Profomance" chips.

    Not sure- one would imagine that two cpu cores would use more juice than a single core.

    Around 30 watts at peak which is about the same as the 1.67Ghz 7447.
    Yonah will be dual core at 2ghz though.
    That's what you call better power per watt.

    Measuring power consumption of just the CPU does not really make much sense when it comes to Yonah. It will be deployed as part of a Centrino platform consisting of CPU, Core Logic and wireless card. It has been reported that Intels latest wireless chip/card uses less power than it's competitors.

    I would not be surprised if the total power consumption is less than the G4/Interpid/Airport Extreme combo we have now :D

    I can't wait to see what type of battery life the new laptops will have with these improvements.:D

    Hope less power used does not equal less reception.
    I need all the reception I can get.

    I think I read somewhere the the yonah chip is 28% more efficient than intel's current chips for laptops. They are expecting 5 hour batterly life with out a problem from what the article said. Sorry I don't remember where I saw it.

    To estimate the battery life of the new machines, look no further than current Pentium M based notebooks.

    I don't think that is a very accurate assessment.:rolleyes:

    Even if dual core does find its way into the iBook, I don't think they'd want to go down in battery life (5 hours vs. 6 hours).

    Yes, but I've never seen an iBook that actually gets 6 hours (or even 5). Apple overstates battery life for their laptops.

    almost all manufacturers overstate the battery life of their products

    Yes, but not nearly as much as other vendors do in my experience.

    This is Apple we are talking about, you aint going to have dual cores in a ibook, Powerbook maybe

    "Average power consumption is typically far lower than maximum power consumption; thus, depending on the notebook and the user, there may not be much variation between real-world power consumption in Yonah and that in current chips. The second core in Yonah often won't be running, keeping average power similar to the single-core only models now available."
    The anandtech artical btw is comparing total system power draws with yonah running on a desktop motherboard.
