Cheap TIM held Ivy back, and IIRC its pretty much been confirmed that Intel is going back to solder. And with the extra time of 22nm under their belt plus other overclocking friendly features being added in to the new architecture, I'd almost be willing to bet 5GHz will finally be a new norm for the enthusiast willing to spend ~$100 on cooling
However I'd bet against IPC improvement being that high, it'd wager it will be closer to 10% at best
Ok, I'll change my wording then, IB on 22nm FinFET isn't tuned for higher clocks than SB managed on 32nm. Point in case, I don't expect Haswell to be different in this area and I haven't read otherwise.
But only barely in the case of http://www.anandtech.com/show/6194/asus-ux31a-putting-the-ultra-in-ultrabooks/8 for example.
I doubt Haswell will bring much of an improvement to desktops. 22nm FinFET isn't tuned for high clocks and Haswell will not bend physics.

They dont overheat. And they produce LESS heat. Meaning your laptop should be more comfortable to use than for example a sandy bridge mobile chip. And there is no TIM/IHS on mobile chips.
You must have a different definition of "upgrade" from the rest of the world.Hopefully this chip will be an upgrade to the 2500K. Ivy was a no-grade (unless you are using a craptop).

With furnace-like heat, yes.

Am I the only one who has trouble with extrapolating his point?Haswell isn't tring to bend physics. And linking to an article about IVB comparring to haswell is of no value , Haswells GPU and CPU no longer share the same power plane as they did with IVB. Also comparring IVB on 3d 22nm to Haswell isn't correct either. SB was built for the 32nm process. IVB is simply a shrink with small improvements. Haswell is made from the ground up for 22nm process and Efficiency. Haswell running at 4ghz and above will perform hust fine . It What Haswell does at 15watts and below that matters this round. That we have to wait to see.
What point the hyperbole?
There is no comparing the operating temperatures of either processor to that of a furnace (TJmax is well below the operating temp of a furnace), and IB consumes less power than SB at any given clockspeed.
The temperatures between SB and IB are not directly comparable because Ivy has a wider thermal envelope than SB. Furthermore, the temperatures in your chart are hardly surprising because:
1) Ivy bridge is designed to run at 1 volt and some change, so you're over volting it a ton at 1.35v. So you're comparing a SB with a small overvolt to an IB with a huge over volt. Not exactly an apples to apples comparison.
2) The die size is substantially smaller than SB. Because of the heat dissipation properties, the temps of the chip will be higher when overclocked.
None of this matters because the chip is designed to tolerate higher temperatures.
To keep things even, we aimed for similar levels of power consumption for the two CPUs, which should translate directly into similar levels of heat to be dissipated. Fortunately, we were able to reach rough power parity at equal clock speeds. At 4.9GHz, the Ivy-based system draws 236W at the wall socket, and the Sandy rig pulls 231W.
Turns out the difference in temperatures between the two was quite a bit wider than the 5°C difference between the thermal throttling thresholds. Our Ivy CPU flirts with 100°C at those settings, while the Sandy Bridge chip is currently running at about 80°C in the same test system.
Your graphs do not appear to have much in common with tech press results who found temperatures far higher at any given clockspeed and runaway power on IVB after 4.8-4.9 GHz.
Who's to say your IVB sample isn't a very good one and your 2600K bad?
Yes 5 Celsius more. However TPR found this -

I dunno why people are pretending that IVB isn't a hot and power hungry chip when overclocked. There's a good reason why the OC community steers well clear of it.
What would make it a bust? And your ridiculous assertion assumes that Ivy Bridge wasn't an improvement over Sandy Bridge, which only a lunatic would argue especially in the face of the evidence that has been presented on this very page.If haswell is a bust then we are screwed because who can justify buying a 3 gen old CPU in a new system
