Haswell CPUs to Top Out at 3.5 GHz
The lineup of Intel's Haswell processors, due for launch in Q2 2013, has been leaked.
Chinese website VR-Zone published the spec sheet, which includes 14 different Core i-4000 series processors, ranging from the Core i5-4430S (2.7 GHz) to the flagship i7-477K (3.5 GHz) model.
Thirteen models are quad-core models, and five versions (all i7 models) support hyperthreading. The fourth-generation of i-processors will be based on the LGA1150 package, which will require those who upgrade from sandy Bridge or Ivy Bridge CPUs to buy new motherboards.
Most interestingly, Intel is lifting the power budget of the processors from a maximum of 77 watts in the current generation to 84 watts at the top end, while the mainstream processors remain at their old 65, 45 and 35 watt power ranges. It is reasonable to assume that the 84 watt rating of i7-4770/4770K processor is based on increased graphics performance of these chips.
I dont see major improvements except for the igp.
Also, ALL models get the same IGP with almost the same clocks, so no Wolfgang, i don't think the increased TDP is because of the IGP, unless there's more to it than what's written here.
I wonder if this will allow the processors to be clocked higher, or if it simply means that they're dissipating more heat via the IHS more quickly. I'd expect power consumption to remain identical to Ivy with the IGP turned off, infact lower, since i remember Otellini saying something like "twice as efficient during idle vs Sandy Bridge" with regard to Haswell's performance.
Didn't expect higher clocks really, it's the same process after all.
Yeah me too! Though it's quad in my case.
Yeah doubt there's much for people who're on Sandy/Ivy at the moment...

Isn't that true for the existing -K series chips as well? (EDIT: it is true, just checked).
EDIT:
More observations regarding the TDP: Some of the the low power CPUs clock as high as the 84w ones on turbo boost, and the only dual core i5 there is (35w, second last in the list) has a minimum of 2.9 GHz (Will pentiums and i3s run at 3.5+???? Or will they all be 35w parts?).
So what's the catch here? the IGP isn't the cause as far as i can tell, unless there are grades of the HD 4600 graphics (like HD4650 or something), but that's unlikely looking at how they've named their IGPs so far. Clearly the lower TDP CPUs (or APUs, really) are indicative of what Haswell is really capable of as far as power consumption and heat are concerned.
What i think is, the standard desktop parts will be able to remain in their turbo state for longer and OC higher than SB/IB could, same goes for the IGP in those parts.
If you're on S775 or maybe S1156, then probably the performance difference is worthwhile. Look at your rig, and ask yourself if an upgrade would make it better for you, or would it just transfer your money to some vendors? What can't you run [well enough] now, that an upgrade would fix? If the answer is "Nothing," then save your money. Step outside the incessant churn of planned obsolescence / perceived obsolescence.
I think that my 920 will last a long time...... I did add a high end SSD to it lately.
It is annoying, since I'm sure it's a wholly artificial limitation. I'm sure they do it so that you won't just buy the top i7, overclock it, and use it in a server or other high-end rig in place of a more expensive Xeon or "Extreme" processor.
Why? Those extra cores won't benefit you unless you're doing heavily-threaded work (video rendering, image manipulation, 3D modeling, etc). I'd rather have fewer stronger cores, as that'd be more universally helpful since most programs can't leverage that many threads.
Also, the higher TDP has me at a loss as well - are they having more heat issues?
Intel could have already given us affordable 8-core CPUs if they had a version without integrated graphics.
Too bad...
