From an older Anandtech article, the lowest powered mobile Sandy Bridge CPU's TDP is 35W. Compared to 10W for Core 2 CULV parts. I don't like the direction this is going.

I'm in the market for a new portable, and I'm looking at CULV for the better battery life and cool operating temps. Even the Core i based low-voltage CPU's can't quite compete (18W TDP). I know TDP != real power consumption, but ...

Specifically, Lenovo's Thinkpad Edge. Newegg has it pretty well priced. The IGP doesn't scare me - this is for web/mail/general work.

What are people's thoughts on this? Should I look backwards essentially 2 generations for CULV? I suppose we won't really know what Sandy Bridge battery life will be for another month or so.

Sandy Bridge as well as the mobile i3/i5 have integrated graphics, right? So TDP are apples and oranges compared to Core2.

They may release more efficient Sandy Bridge chips later.

TDP!=actual consumption, especially if you underclock/undervolt and especially if it includes graphics stuff yoiu're not going to use

A N550 should be fine for most users for web/mail/word processing and TDP is lower than Core2. It's cheap too.

AMD might release something a bit better than an N550 with a TDP in the CULV range.

Ah yes, foolish me. They steal other logic from the NB as well (memory controller). Forgot about all that.
