Why take a chance on getting a golden Sandy when a normal IB chip will be faster anyway and it's hit or miss whether you are going to get high clocks on either chips. Everything about Ivy is better even if only by a small amount. Taking a chance on getting a 2600k that will do 5ghz seems crazy to me.
If you say so. Lynnfield to Sandy bridge was a huge jump. 15% more IPC and had way more oc headroom. My old i7-870 was able to hit 3.9ghz, but my SB hit 4.8ghz with ease. Thats more IPC *and* better overclocking. But Ivy Bridge???? The IPC difference between SB and IB is laughable, 3-5%? And it overclocks worse? Oh wait, you get better iGPU? WHO CARES?
Look at the above graphs, many reviewers aren't even able to hit 4.6ghz stable. For a new purchaser IB makes sense but for existing SB users, IB is a joke.
SB TJMAX is 98C, IVB TJMAX is 110C.
@ 1.1V IB runs 4,25C hotter then SB with HT off. (16.03%)@ 1.2V IB runs 10,75C hotter then SB with HT off. (36.44%)
@ 1.3V IB runs 15,00C hotter then SB with HT off. (44.11%)
@ 1.4V IB runs 24,75C hotter then SB with HT off. (65.56%)
So if you're lucky enough to get 4.6ghz at 1.1V on IB you're good. NEWS FLASH, MOST REVIEWERS REQUIRED 1.25V+ TO GET 4.6, and *some* weren't even able to get past 4.5ghz.
At 1.25V your temps will be 45% warmer than SB. Good luck with that. Ivy Bridge is a complete disappointment for air overclockers.Edited by xoleras - 4/24/12 at 7:48am
