Haswell CPUs to Top Out at 3.5 GHz

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.

    nope.. gonna stay with my 2700K 4.5Ghz till 14 nm Broadwell.... thank you.

    I dont see major improvements except for the igp.

    and they're still deactivating VT-d on the unlocked chips. That's annoying. I'll stick with my 2600k for a while longer. It OCs to 4.6GHz easily. Why bother to upgrade?

    Do we really need that much choice? What's wrong with 'High End', 'Mainstream' and 'Budget'?

    LAME. New motherboard again. I wish both AMD and Intel could come up with something to work for a few generations anyways.

    Very interesting! Higher TDPs on all the standard desktop parts and a 35w quad core with HT at the other end!

    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.

    mad techRelease it already i am w8ing to upgrade from crappy core2duoYeah me too! Though it's quad in my case.

    Onikagenope.. gonna stay with my 2700K 4.5Ghz till 14 nm Broadwell.... thank you.Yeah doubt there's much for people who're on Sandy/Ivy at the moment...

    dgingeriand they're still deactivating VT-d on the unlocked chips. That's annoying. I'll stick with my 2600k for a while longer. It OCs to 4.6GHz easily. Why bother to upgrade?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.

    Stop it with the graphics in CPUs!!
