No it doesn't. I was at an Ivy Bridge launch event yesterday which included demonstrations of overclocking up to 5Ghz. This was with an i7-3770K, MSI Z77A GD65 motherboard and Dark Rock Pro cooler (think Noctua NH-D14). In open air (test bench setup) 5Ghz was resulting in CPU temps of around 75C. The opinion there was that IB could be overclocked to higher levels at lower temps than Sandy Bridge, with lower CPU voltage increases.
That goes against just about every review and test of Ivy Bridge that I've seen online. Even with decent water cooling people have been getting unacceptably high temperatures before they hit 5Ghz. Many overclockers have been bitterly disappointed by Ivy Bridge and are planning to stick with Sandy Bridge instead.This review
at Hardware Canucks is pretty typical:
To put it simply, we think that the term "blazing hell inferno" might be short-selling Ivy Bridge's heat problem once you cross a certain threshold. Past 1.30-1.35V temperatures skyrocket, so we're going to recommend that everyone on air-cooling, even high-end air-cooling, stay in the 1.25V-1.30V range. Most chips shouldn't have any problems hitting 4.5GHz with 1.20V or less, which is awesome for your average casual overclocker, but scaling gets progressively worse as you go above these levels.
Our overclock was stable, we threw every app we could at it and had four 2-3 hour gaming sessions, but we aren't going to hide the fact that during the one hour AIDA64 stress test at least one core hit a truly absurd 101°C, while the others routinely reached into the 90's. At least that proves that these new chips are resilient to short-term heat.
I think the original post is correct. Ivy Bridge is a nice upgrade for people like us, but not on a par with the previous generation for the maximum performance overclockers.
