    Just wondering how a SU2700 compares to a SU9300/9400/9600. They both use 10W at full speed, yet the 9 series are dual core. What did Intel do? Take a 9 series and use only one core and call it the Pentium? How does this single core use as much as a dual core, and would they both get the same battery life in a computer like an Acer Timeline?

    SU2700 (1,3 ghz) seem to be a low-priced cpu for the netbook market. So its TDP isn't impressive since the SU3500 (1,4 ghz) has only a 5 W tdp (but it's more expensive i guess).

    SU9xxx as you said are dual cores and performs much better for the same tdp (10 w)

    I know, but I want to know why the SU3500 has the same tdp as a dual core.

    The same TDP doesn't mean it uses the same amount of power.

    It's cheaper to validate the same CPU at a higher TDP than with a lower TDP. Plus, the same CPU with lower TDP will fetch a higher price in the market.

    Think of it this way. Why does a Core 2 Quad QX9300 use only 45W for quad but a Core 2 Duo E8600 use 65W?

    The Core 2 Quad QX9300 is mobile, uses less voltage/current etc.

    SU3500 is a 5.5W TDP cpu as shown here. My understanding is that it's a single-core SU9400.

    exactly what i wanted to mean.

    SU3500 is a monocore so it's quite logical that it has half the TDP of the SU9xxx dual cores. SU2700 is a monocore with a higher tdp so less expensive and destined to the low-range mobile market.

    You may be right. That's the only logical explanation. Otherwise SU2700 should have the same or lower TDP than SU3500.

    Edit: Or the Pentium uses a different core than Core 2 CPUs. That would be another explanation.

    They both use identical silicon. Intel can say that the TDP is whatever they want and these numbers are almost meaningless when talking about power consumption. Keep in mind that the Core 2 is sold for ultra portables and that the Pentium is sold as a budget chip.

    I agree about the TDP. But both SU2700 and SU3500 are used in Acer 3810T for example.
