That's even better than I thought; I assumed it was 4-3-2-1.The i7-4790K represents Intel’s first ever consumer processor with a base frequency of 4 GHz (we have CPUs that turbo this high), but the turbo mode for this processor is actually 4-4-3-2, meaning that at single core loads the user will see 4.4 GHz and at full-core loads it will be 4.2 GHz.
That's even better than I thought; I assumed it was 4-3-2-1.
So even if all four cores are loaded, you still get 4.2 GHz guaranteed at stock voltages, even on the crappy stock cooler.
Again, I can't see why people are complaining about this. :awe:
If I want baseless speculation posited as fact I'd watch TV news.The average overclock for this will be +100-300MHz, which is basically no performance increase. This would have been more impressive as a locked CPU.

How long do you guys think this new i7 will be a good gaming CPU? A good 3-4 years?

Indeed. 4.4ghz required 1.2V+ on the 4770k (for MOST 4770k CPUs) which is simply a no-go on the intel stock cooler. The fact that this chip can get 4.4ghz on the crap intel stock cooler at 1.1x V? It's a definite improvement. It definitely is better binned with improved power delivery. Some folks are complaining just because.
No, it isn't designed to be an upgrade for anyone with a 4770k. I can't believe that is being argued as the main perspective. But it WILL be a great upgrade for those coming from lynnfield, nehalem and SB CPUs.
Well, to be fair, 4.4 stock is *not* on all 4 cores like it would be on an overclocked 4770K. So the comparison is not totally valid. A more accurate comparison of stock 4790K vs overclocked 4770k would be to use 4.2ghz as the 4970k clock on all 4 cores.
That said, I agree it is a nice improvement, especially since there was no price increase, and I agree some posters are just being overly negative, and are assuming overclocking will be no better than 4770k without sufficient data.
Personally, I think it will be somewhat better on average, since the 4790K is already basically overclocked to 4.2ghz with the stock cooler, and I doubt many 4770k would achieve that. Even if it were no better, so what, it was overhyped (like that is anything new for either intel or AMD), but you still get the same or better performance for the same price. Edit: and undeniably better stock performance.
I believe DC will get in to high voltage wall after 4.6-4.8Ghz and above with AIR and WC. So just because it can operate easily at 4.4Ghz doesnt translate in to very high OCs. In fact LN2 ocerclocks didnt brake the 6.5GHz barrier (maybe they run in to coldbug ??).
Depends.
I believe it is possible to dissipate upto 1.5V on Water if you have a high-end loop.
At those volts, the max frequency would be around 5Ghz or a bit higher.
I wouldn't use 1.5V on FinFets unless you go sub zero.

1.5V on Haswell is almost certainly going to degrade the chip very fast. Even 1.4V is going to kill it quickly imo. I've degraded followed by completely killing a SB-E with 1.4V over the course of about a year or so.
I don't think Haswell really can withstand much more than 1.3V for long-term use, even that might be too much. My 4670K gets really hot with just going over 1.2V in my experience.
