Will Haswell and Ivy Bridge overclocking properties be similar?

heck, if O/Cing is all you care about you should get a BD. they clock sky high. what we're really looking for is O/Ced performance, and Performance/Watt.

Why is everyone expecting Haswell to overclock better? Same process but an enhanced IGP and VRM's on Die. It'll probably overclock worse.

That's...not entirely accurate. I don't know how much you followed Intel's stuff back in the Merom days, but a big deal was made about how Intel would deliberately "slow" down parts of the CPU in the name of perf/watt at the stock frequency. That is, they would literally gimp overclocking because restricting those circuits/paths to a certain, lower clock speed would make those parts of the chip much more perf/watt efficient.

Clock speed ceiling is very much limited to the micro-architecture. I suspect the move to 22nm didn't really get us more clocks because IVB's key focus is on making a much more perf/watt compelling SNB for laptops and at the same time trying to get their 22nm process right.

Haswell is a new micro-architecture actually designed from the beginning around 22nm tech (which should also improve), so it's very likely that they'll want the CPU to be able to run at higher frequencies. Also, integrated VRM = GOOD THING! For overclocking or pretty much anything.

Absolute clock speeds are meaningless. I'm more interested in the % increase in performance we can get over stock, and of course stock performance.

If Haswell clocks in @ 500mhz stock (and blows everything away), and OC to 1ghz, will it be an 'epic fail' because of low clocks?

IB on 22nm is disappointing (if the rumors are true), but it IS just a shrink on a process that (imho) is geared more towards low power.

So say Haswell eeks out 500mhz more from the 22nm process. Will you guys be happy with 4.8-5.3ghz? I find it a little disappointing.

It is not all about Mhz. You should read the MANY threads about the new Haswell instructions.
