News - Intel Haswell leaked power usage details are confirmed

[HEXUS]

Almost half the power usage of the most efficient Ivy Bridge processors.

Until these are released we will see if the claims are borne out in reality.

They haven't really failed to deliver since they first came to market with the Core 2 duo's though have they!

If you look at how much the media were getting excited about finfets last year(and some big websites even hinted that IB would be out last year too) and people bigging up IB as the next coming, and the IB GPU claims ,yeah,I am going to wait until Haswell is released to retail first! Intel has a very good track record,but it has not been entirely perfect either.

Power reduction really does interest me,being a SFF PC fan,but the proof of the pudding is in the eating!!

[Domestic_Ginger]

The Intel marketing department is as well funded and creative as the research division!

It will be time to upgrade I think late this year/early next year. So quite interested in goings on.

Interesting indeed, seems Intel are going with the flow and getting to grips with the fact that ultrabooks/tablets is the direction the industry is moving towards

'That’s all the Haswell info I have for now but keep your eyes open for more Intel news and views from our own man at the IDF - Tarinder. The show starts today, but US Pacific time is 8 hours behind Blighty so he’s probably still scoffing fluffy buttermilk pancakes and maple syrup at the hotel.'

Ahem, I wish.

Let's see what Dadi Perlmutter, General Manager, IAG, has to say in a couple of hours' time.

I'm sure there was something that I heard that Intel released... Something to do with a P67 Chipset's SATA ports perhaps?

Not to mention Larrabee... ahem!

It's potentially interesting if it's as good as the marketing would have you believe, but reducing the TDP can mean next to nothing.

TDP is just a guide so system/thermal solution manufacturers have a round about idea of how much heat they need to get rid of, a chip's max realistic power can be way above/below that value, and it even varies from die to die depending on yields.

As an example, a mITX Celeron G540 system I have doesn't pull more than 54w from the wall even under an unrealistic load (OCCT PSU stress test, which also stresses the GPU), despite the 65w TDP. Because of the sizeable margin, Intel/AMD could easily change how they decide on the TDP and set it way lower for at least some of the models.

As always, take marketing/conveniently 'leaked' documents with a pinch of salt.

[shaithis]

Perhaps the first silicon to sport a rudimentary form of the NTV tech?

Can't see them getting the TDP down that much any other way but another sizable die shrink.....and surely they aren't doing that again so soon?

[watercooled]

Haswell is a tock, so it will still be using the existing, albeit refined, 22nm process. And the power benefits of shrinking the process are smaller than they used to be, because of increased leakage among other things.

[hiyayhi]

these processors will only be any good if the AMD piledriver cpu's are actually competition, otherwise it's just gunna be a processor thats a slight bit better than ivy bridge and make amd look like a pile of crap in the cpu department again.

[watercooled]

CPUs take longer than 5 minutes to run through R+D, trial production, more R+D, more trials .... final production believe it or not. Haswell, like all other CPU architectures will have been in development for years, they can't change their mind on performance last minute like some people seem to think. At most, they could charge more/less depending on competition for a given CPU/clock speed, but it won't have any impact on performance/power.
