Core i7-2657M is a new Ultra Low Power CPU from Intel, its TDP is 17 watt with a 1.6 GHz clock speed.

So will Intel release this year another Ultra Low Power Core i7 with TDP 17 watt, but with higher clock speeds than 1.6 GHz???

I am asking a technical question, what I mean, is their any technical barriers that prevent Intel from producing an ultra low power high end CPU without lowering the clock speed greatly???

------------------------------------------------------------------------------------------------------

In the past years Intel produced:

Core i7-620UM / 1.07 GHz / 18 watt
Core i7-640UM / 1.2 GHz / 18 watt
Core i7-660UM / 1.33 GHz / 18 watt
Core i7-680UM / 1.47 GHz / 18 watt
Core i5-430UM / 1.2 GHz / 18 watt
Core i5-470UM / 1.33 / 18 watt
Core i5-520UM / 1.07 / 18 watt
Core i5-540UM / 1.2 / 18 watt
Core i5-560UM / 1.33 / 18 watt

None of them was above 1.6 GHz, so will the Sandy Bridge be any difference?

The 2100T 1155 uses a max of about 25 watts, and is priced at around $130 on ebay for the bare cpu only. That's what I would use. Many of the low wattage stuff is for mobile boards only or very pricey and hard to find. If you have a laptop then your choices are correct.
