What is the rationale behind integrating the voltage regulator in Haswell?

[rickon66]

Them rascals at Intel, what will they do next-intergate the math co-processor to try and screw us?

I'm glad someone said this, because every time intel makes a change, this argument is brought up and every time the chip is an exceptional overclocker.

Yeah you get a couple expensive 1155 chips they allow you to oc. Out of the dozens they make.

Their non-k cpus are so Boring (go up 400mhz for some models, yay). You can't even base-clock them anymore. I'm glad Intel hasn't choked ocing

Expensive? They carry a $10-$20 premium over the non K models and people are hitting 4.2-5GHz+ on air without bclk. That's huge. You're complaining for the sake of complaining. Nothing more nothing less. Come back when Intel is actually locking down over clocking to expensive CPU's. Then what you just said will actually be true instead of pure BS.

$200-$300 is not expensive for wanting to oc a cpu? Wish I had your paycheck. Ocing $50 cpus is much better like it used to be.

Ya the way it use to be was stupid from a manufactoring and margin perspective. Intel did it right . Its an insult to people who buy the higher end cpus . AMd has to offer cheap unlocked cpus or no one would buy them . I surprized IDC hasn't jumped in here on this process design on skrinks. SB was made for 32nm . Ib isn't designed around the 22nm process. You can talk all you want but your full of it . Haswell design will be alot differant than IB were as IB is much like SB.
All one has to do is compare the first 32nm intel chips with sb . I understand perfectly what your about.

Problem with overclocking a $50 cpu is it still performs as a $50 cpu.

These Semprons still suck, even overclocked.

I dont think so. Plus its 3-4 times less than what we payed in 7-8 years ago.

And as said, those 50$ CPUs performed poorly. Even OCed.

 

[formulav8]

Thats fine and dandy, to each his own. I can't afford $200-$300. But I would still like to oc. But since i'm poor i'm not allowed to says Intel. (Well i'm actually well off but having to spend over $200 to simply oc a cpu is nutty to me.) I just bought a G620 and its as boring as can be. (Well, not for me to keep personally. And I oc more for the fun of it and not that the power is actually needed. Which is nearly everyone here anyways.). Intel forces you to pay them over $200 to oc. I want to tinker with a cheaper dual core not an expensive one. Used to be able to do that. But Intel purposely killed ocing except for having to buy high priced models. And 7 years ago you didn't have to buy specific higher cost cpus to oc. You just needed a mobo with the features.

PS: I recall ocing e5200's and the likes as being great performers, not poor performers. Especially when oced. But nothing like that is possible anymore.

But anyways, to each his own opinion. Have fun gotta run

They'll integrate the memory, sound card, network card, wifi, disk controller. Wanna upgrade any of those with non-Intel parts, or mix and match components how you want? Or upgrade the cpu without replacing your entire system? Nope, sorry - that's gonna cost you a whole new CPU and everything in it.

Thats would fulfill everything Intel has ever wanted.

 

[ShintaiDK]

Btw, in case anyone forgot. We got locked CPUs because of counterfeits. For example selling a P2-266 as a P2-300 and so on.

Sound and disk and somewhat NIC is already integrated into the chipset. And chipset or CPU is a potatoes potatoes thing.

"Integrated voltage regulator" is pretty vague, and probably only means the logic part of the regulator. I'm willing to bet the chokes, caps, and even the fets are all still external to the CPU. Is there any more descriptive info available?
Some of these devices are starting to draw 100A, or as high as 300A in some multicore network applications, where it becomes very difficult and expensive to design a power supply that can regulate 1v at that high of current. I'm surprised that hasn't happened sooner.

 

[Zucker2k]

This may well be a second level vrm to enable for ultra-low voltage regulation; think less than 10mw.

I think Intel is already implementing the knowledge gained in the NTV research into Haswell and future processors; the claims made in the linked article are quite consistent with similar claims for Haswell. Intel will surely leverage this technology across platforms so smartphones, tablets, notebooks, and desktop all stand to benefit from incredibly power-efficient chips.

NTV allows really low active power, but frequency at that power level is quite archaic. The lowest voltage mode Claremont only runs at 3MHz, which is in the 386 range. At its top frequency of 915MHz, it uses 737mW.

Notice that Atom Z2460 running at 1.3GHz only uses 750mW. There's a reason minimum frequency on LFM is rather high at 1.6GHz(800MHz for laptops). Even hardware offloaded video playback requires some CPU power to run it fluently.

It's a proof of concept. It's at least few years away, and application might be limited. But that's what research is. Don't confuse with Haswell though.

This may well be a second level vrm to enable for ultra-low voltage regulation; think less than 10mw.

Atom Z2460 only uses 50mW @ 100MHz. And its out already. The VR there must be able to handle that no?

I'm surprised that hasn't happened sooner.

Sure, its so easy.

They are Sandy Bridge Celeron class, when unlocked into dual cores and clocked @ 3.3 Ghz or higher.

Not sure, what integrated sound you were referring to here.
