    Question-
    Will the sandy bridge processors (I7) run cooler then the I7's right before it? I was reading on the Cnet forums, and it appears the I7's before sandy bridge can run a little warm in a laptop.

    They're 32nm and consume less power but I don't how this translates in measured temperatures. I'm looking for a comparison too.

    The Sandy Bridge i7 consume around the same power. The Clarksfield i7s are 45 nm but do not have the IGP on the CPU die. SB i7 are 32 nm but now have IGP so TDP is still 45 watt. But clock for clock SB beats the Clarksfield i7 hands down unless you have an Extreme.

    They will definitely run cooler. They are more power effecient and along with that comes with less heat to dissipate.

    Or, think of it like this: with the same workload, over the same time period, the new SB platforms will be cooler because the CPU will be pegged for a much shorter time at 100%. It will spend much more time in C3/C6/C7 sleep modes than the older (and hotter) tech can.

    Of course, the corollary is that, as always, final temperatures will depend on the cooling built into the notebook. Given the higher efficiency of Sandy Bridge, some manufacturers may be tempted to skimp on cooling again, like they already are in the case of battery life on some of the new Zacate notebooks.

    read the spec sheets at ark.intel.com

    a 45 watt (or 65, 95, whatever) heat budget is the same as any other 45 watt heat budget.
