Intel has created a rod for its own back in recent years by delivering ever more performance.
The new Ivy Bridge generation basically puts on the brakes.
No more cores. No more clocks. And no more overclocking headroom.

Unfortunately, practical experiments uncover a few unpleasant issues. We tested two different Ivy Bridge processors in our lab, but none of them managed to achieve stability at the frequencies reached by their previous-generation predecessors

The temperature is higher than we'd like, assuming it's being reported correctly, and the spiralling temps for Ivy Bridge chips may be a cause for concern for SIs whose best-selling systems - currently based on Sandy Bridge - tend to be overclocked to 4.5GHz-plus.

Ivy Bridge can be overclocked, but at least initially it's not going to be as good of an overclocker as Sandy Bridge. Over time I expect this to improve somewhat as Intel's 22nm process matures, but by how much remains a question to me. It's unclear just how much of these limits are by design vs. a simple matter of process maturity.

Overclocking the Third Generation Core i7 3770K was a little more challenging than I expected, as the usual means to gain additional clock speed did not seem to work after a certain point. My expectation was to go for 5.0 GHz right off the bat by adjusting the clock multiplier to 50 and voltage to 1.40 V. That did not end well.

With this setup we were able to boost the clock speed of the 3770K up to 4.8GHz, at 1.36V. At this speed the processor is running each core 37% higher than the base clock, and 23% higher than the Boost clock. We also could have scaled the processor higher, but we were already hitting temperatures of nearly 78°C, so we decided not to push it any further

However, those hoping for drastically higher frequencies in comparison to the Sandy Bridge will be disappointed, despite the CPU’s maximum multiplier rising to 63x. While much higher frequencies are now possible, you’ll need exotic cooling to reach them. We’ve found that the smaller production process and increased transistor count leads to hot-spotting on specific cores at higher frequencies. Three cores will be rock solid, but one will inevitably fail under load.
Our i7-3770K topped out at 4.8GHz (48x100, VCore 1.34V, Load Line Calibration = Extreme), reaching a peak delta T of 72°C in a 19°C ambient. Regardless of adjustments to the multiplier, base clock, core voltage or IGP, it simply would not remain stable at any higher speeds,
wanted to post a few just to prove the point. if you had any idea what you were on about, this would not be necessary. but i feel it is important that the OP is no mislead by incorrect information.
