Power Consumption
Intel isn't really exploiting 22nm for significantly higher default or max turbo frequencies. While it does seem like you'll hit turbo frequencies more often with Ivy, most of what 22nm offers will be realized as power savings.
At idle, all cores are already power gated so there's not much more Ivy Bridge can offer. We see savings of a couple of watts at most over the 2600K but otherwise it's nothing significant. In notebooks I'd expect to see implementations of DDR3L help keep power consumption down, but at idle there's really not much that can be done.
Under load however the power savings are significant. The Core i7 3770K pulls 27 fewer watts while delivering better performance than the 2600K. Again, translating this to what you can expect in notebooks I'd say that peak battery life likely won't be affected, but battery life under load will be better with Ivy.

All that revenue, all that profit and yet, they STILL can't bet AMD in integrated graphics.I think that qualifies as a fail.
Thanks for (kind of) proving his point?

They don't really care to. The point of a business is to make money, not have the best products. The latter only gets solved when AMD gets serious in competing with Intel on power/performance again.Operandi - Tuesday, March 6, 2012 - link

You know what? All you do is bash AMD.If you think AMD sucks THAT much and it's engineers and everything else is incredibly bad...
Then I have a challenge.
Go build your own Processor or GTFO with the bashing.

Except... Intels IGP drivers on Windows are bad already. They are allot worst on the Mac.Historically Intel has never supported it's IGP's to *any* great length and even had to throw up a compatibility list for it's IGP's so you know what games they could potentially run.
Here is a good example:

Heck I recall it taking Intel a good 12 months just to enable TnL and Shader Model 3 on the x3100 chips.
Historically the support has just not been there.

AMD's CPUs are going to die...sucks to be an AMD fanboy. However, whatever they are doing with their dedicated GPUs, they are doing something right...if they can manage to pull their act together on the driver side, I think AMD would live as a GPU company...earthrace57 - Tuesday, March 6, 2012 - link
I'm sorry, but Llano APUs will stay on top for quite a while; Intel is still at heart a CPU, Llano is part GPU...if AMD can get drivers the quality of nVidias, they will most likely do extremely well on that front.zshift - Tuesday, March 6, 2012 - link
I really enjoyed the added compilation benchmark. This site has the most comprehensive collection of benchmarks that I've seen, it's a one-stop shop for most of my reviews. Keep up the great work!Jamahl - Tuesday, March 6, 2012 - link
Would be great to see power benchmarks of the IGP, especially vs Llano and the HD 3000. Let's see if the graphics improvements have come at the price of yet more power consumption or if intel has managed to keep that down.
