***Official Intel Haswell Thread***

tbh said:
That headline is a bit sensationalist, probably an attempt to get more views.

It's only the ultra-low power states which can cause issues, and it will take the whole of ten seconds to go into the BIOS and disable them.

Mobile devices will obviously want to have them enabled, but they ship with their own PSUs anyway so compatability shouldn't be an issue.

If it was me going for a Haswell replacement I would want to build around this feature its very appealing for peeps who dont want to have the PC off at all. It would be very nice for remote access home server :D
 
Intel Brands Haswell GT3 "Iris," Desktop Variants Planned

With its 4th generation Core "Haswell" processors, Intel is putting in a serious effort to improve integrated graphics (IGP) performance to catch up with AMD's Radeon HD 8600 series on its latest APUs. There are three classes of Intel IGPs for Haswell, the GT1, which features 10 execution units (EUs), and will feature on entry-thru-mainstream Pentium, Core i3, and Core i5 chips; GT2, which features 20 EUs, featuring on mainstream-thru-performance Core i5 and Core i7 chips; and GT3, a large 40-EU IGP, which uses an L4 eDRAM cache. Chips with GT3 graphics are multi-chip modules (MCMs) of the CPU die and this eDRAM due, as detailed earlier. It was earlier believed that Haswell chips with GT3 graphics cores will be confined to notebook and Ultrabook-specific CPU models, but it turns out that it will make an appearance on the desktop platform as well.

Intel is carving out three further variants based on the GT3 IGP silicon, probably based on clock speeds. The top variant is named Intel Iris Pro 5200, the next one Intel Iris 5100, and the last Intel HD 5000. GT2-based IGPs follow an Intel HD 4600/4400/4200 nomenclature. Desktop processors with GT3 graphics will get the -R brand extension, for example, Core i7-4770R. These chips will probably lack unlocked base-clock multipliers of the -K chips, could feature different CPU clock speeds, and interestingly, feature lower overall chip TDP than the -K chips. The i7-4770R, for example, is rated at just 65W, compared to the 84W of the i7-4770K. Merely being on the desktop platform doesn't mean the chips will be "DIY" or based on the LGA1150, we won't be surprised if the chip comes in BGA packages, which are soldered to motherboards.

8 pack 8-10 percent faster maybe :p come on :D

cant see it being much of a leap over ivy tbh how can they in such a short time. so im going with 8-10 percent at best.
 
Any news on overclocking potential? I read that they have improved the memory controller enabling higher clocks with all 4 Simms populated.

It would be good if they could make it so that the GPU would still give some benefit to people running a high end dedicated graphics card... For example free anti aliasing or something. Not sure if this would be worth doing or even possible though... Would probably introduce more input lag if it is even possible.

Ivy was "tock" of Sandy and sandy launched almost 2.5 years ago, they can do it in such a short time as Ivy-Haswell is new architecture not just a mod of an existing architecture (like i7 920-2600K instead of 2600K-3770K)

Ivy was a "tick"; the tick-tock cadence is centred around process technology rather than processor microarchitecture.

I have so got the itch to upgrade, dont need to upgrade as the i7 920 is still rocking on, very good investment there but I just feel the itch coming on.

Roll on Haswell :)

Same with me, my 920 is OK at the moment but I don't want to fall too far behind when upgrading and it has been a while.

I might sell off my 920 soon put the money aside until Haswell is released.
 
I don't know if this has been posted before but if true this is very impressive.

An Ivy Bridge i7-3770K part scored around 1560 in 3DMark 2011 [source], thus the new Iris Pro-equipped chips should be scoring over 3000, if Intel's performance claims are accurate. That indicates that the Intel's on-die graphics will be slightly better than a full discrete AMD Radeon HD 7750 GPU which scores around 2900 [source].

Could be bad news for AMD and Nvidia as now Intel has a part that's not only eating away at the low end but now is starting to creep into the mid range.

I wouldn't mind getting a hold of one of these new Iris Pro level chips and seeing just how much extra performance can be gained from overclocking it. Overclocking current gen HD3000 series can yield huge gains so one can only assume the same will be true on Haswell.

Edit:

I see Kaapstad has already posted something similar.

I was hoping for a <77w 4770k, at least with the onboard GPU disabled.

Haswell top end is meant to be 84 watt TDP, what would do with that 7 watt saving? Submit it as prove that you can be loyal member of greenpeace?!?

If a 7 watt lower tdp is really what is wanted, just run lower clocks and volts. Intel could hit stock 77w tdp if they wanted but it's only relevant to stock speeds (and would reduce perceived generational performance jump) and means nothing to someone who can over/underclock.
