AnandTech - Ivy Bridge: A Tick+ With Configurable TDP
If this is true then we could run the M17x at an indefinite turbo limit for an indefinite period of time as long as the laptop stays cool enough. so 4ghz shoudl be quite easy on a laptop cooler............WOW
im really hoping the ivy bridge CPU is a drop in for the sandy bridge laptops and all these features are on the CPU no the new chipset.

Well, Ivy Bridge is supposedly backwards compatible with Cougar Point, so this should be possible. BUT this is just a rumor and it also depends whether ALW decides to provide BIOS support. I'm more interested in next-gen GPUs though, should see a 2X performance increase...

With Ivy Bridge Intel will be bringing the average TDP of their CPU way down rather than targeting increased performance at the same TDP we see on SB now. In other words instead of 25W-35W mainstream dual cores and 45W-55W quads, we'll see something like 10-15W dual core and 20-35W quad Ivy Bridge that offer about the same performance as Sandy Bridge. Better performance per watt, but no extra processing power.
What Ivy Bridge's configurable TDP sounds like is that the new CPU are still plenty capable of running at the old SB TDP levels but Intel is leaving it up to the user to unlock that potential if they need more performance.
So a hypothetical Ivy Bridge i7-3920xm @30W might not be any faster than Sandy Bridge i7-2920xm @55W but dialed up to a higher TDP the IB would become faster.
In the end you'd not so much be running a constant overclock as you'd be removing a default underclock. -

hope you can configure it with ALL mobile cpus and not only extreme ones...
Now you can also change TDP (even with nehalem) with throttlestop. Choosing a certain mutliplier reveals a new TDP. -
The 2920XM already has this feature but many laptop manufacturers have decided to lock and disable this feature in the bios. Intel can come up with some great features but they've also given the people writing the bios full control over what features you will be allowed to access so an unlocked CPU could be meaningless.

The only way I could see Ivy end up in the R3 is, if Dell sell the R3 with a Ivy in it adding BIOS support. That would be unlikey, as the new chipset will likely be released at the same time as the new processor.
Let hope by some small chance that there is a delay for some reason or problem with the new chipset (which I doubt after this year) and Dell just jams in a Ivy in to the current chipset.
Other than that, is someone would have mod the BIOS to support an Ivy processor, which again is unlikey, as I haven't ever seen anyone doing these kind of mods? -
AnandTech - Intel's Ivy Bridge Architecture Exposed
so it seems only the ULV and Extreme chips will offer configurable TDP. Nothing surprising there. Although this will make notebooks like the Macbook air much more versatile. To the point that a 15inch Air might actually make sense.
the 65W extreme processor will also be more attractive. 65w is a pretty sensible limit for a notebook. My R3 with a 45w chip gets to 75-80c without a dedicated cooler.
PS. Im assuming these are not limited by bios in anyway.
Ivy bridge with configurable TDP and indefinite turbo limits???
