***Official Intel Haswell Thread***

[illuz]

The was a report after IB came out that hypothesized that IB couldn't physically withstand as much long term voltage through it as Sandy, and so Intel had used the TIM to create an artificial "heat barrier" to prevent people being able to take the chips to the voltage level that would result in exponential degradation, nothing was ever proven though I don't think.

Then it turns out IB can handle voltage way better than Sandy...

Not sure if posted already?

A final observation should be made in regard to overclocked states. An overclocked 4770K, even with water cooling, was too hot and unstable to complete Cinebench 11.5, or run intensive benchmarks like Prime95. This problem (instability at high/very high temperatures) carries over from Ivy Bridge, it seems.

they use cheap paste to deliberately cripple performance imo,so not to hinder x79 sales

Yup, my thoughts exactly lol

 

[PCZ]

I think they use cheap paste to save money.
It hinders Overclocking for sure but I think that was not the primary driver for the change.

Perhaps 8Pack can tell us if he bothered de lidding or just used extra LN2 to get the 7Ghz run.

 

[BigBANGtheory]

Who is to say Ivb-E will have solder?

Money saving vs. power user reputation and bad press I guess. Which does Intel value the most?

What we have heard from un-confirmed sources is the implication that Haswell also 'runs quite hot like IvyB', which to me at this stage I read as more paste. Hopefully the full retail version of Haswell uses better paste atleast.

The fact that the supposed admin running the overclocked Haswell in the table above couldn't get past 4.5GHz with water cooling is not a happy message, I sincerely hope that is an engineering sample they had there.

intel don't cut corners to save on solder,they do it so they can sell more enthuisiast x79/hex core chips

 

[PCZ]

They were Retail chips being tested.
Had picture of the Boxes.

Launch isn't far away so stock has to be in the Channel.

 

[Boomstick777]

Thinking the same thing. Almost seems as if the mainstream chip are used as a testbed for the process and limit overclocking with dodgy tim so the Enthusiast CPU's are the best option..

Oh well, will wait for 4930K / 4960X for my next upgrade

So you think that someone in the market for X79 would change there mind if IVY got solder instead of paste under the IHS ?

Really you think that ?

 

[sniperone]

I should hope so I got £500 for it, I hope £320 should cover CPU and £180 for board.

You think the cpu will really br priced that hi ? I thought about £300 max for the cpu and £200 maybee a little more for a good asus board

 

[Dave2150]

Waiting for Anandtech review before reading too much into these leaked results

 

[Tackle_Berry]

No I think it will be a bit less but just incase I have put that much aside

 

[sniperone]

Best up my budget to about £600 then just to be on the safe side

no,im thinking why would new pc builders choose x79 over a good clocking haswell chip? guessing at 5ghz on air and soldered die

if paste it will drop you down to 4.6ghz on air due to much higher temps

again I could be completely wrong,its all speculation,but you know how intel likes to make money by switching to new sockets and locking/unlocking certain cpu's ect plus other things

Intel Core i “Haswell” Microprocessors May Require New Power Supply Units for PCs.

"As it appears, Haswell's C6/C7 states require a minimum load of 0.05A on the 12V2 rail, and many desktop power supply units (PSUs) just cannot provide that low current, reports The Tech Report web-site. Numerous older PSUs, which comply with ATX12V v2.3 design guidelines that only called for a minimum load of 0.5A on the CPU power rail, can be equipped with a less sophisticated internal feedback loop/protection, reports VR-Zone web-site. As a result, unless C6/C7 power states are disabled in the BIOS, PCs with older/cheap PSUs may become unstable when processors enter these states."

^^^ lol I wonder how much £££ psu makers bundled intel for that one

 

[ubersonic]

This was addressed a few pages back, if you have a cheap PSU you can just disable the settings in the BIOS.

True, though one of the incentives for a user like I who will be upgrading from bloomsfield (i7 920) to haswell are the huge power savings. Having to disable some of those power savings or purchase a new psu is quite frustrating!

Hopefully my trusty old Enermax Galaxy 1kW will be compatible

I got bad news for you
