Ivy Bridge OC Results Came in (Engineering Sample)

[Nemesis 1]

Well if ya go MSI and I would . Its a great M/B likely the best. The GD 80 is te way to go. In my case anyway . As I haven't alot of storage room so I will need the Thunderbolt tech for storage and daisy chain.
AT preview of IVB was worthless. Thats right it was worthless . Thats not just because AT seems to push ASus M/B only. A preview of IVB on a 77 series chipset without using Lucid virual v syn. is a joke. Than if you use the performance mode it really puts the preview in a bad light. Looks like someone is trying to sell needless highend AMD graphics cards. The fact AT never even mentions Lucid is in itself an oddity. Wait till you see this thing in lucid performance mode . Keep your old GPUs they have lots to offer . What if a NV 560 ti could slug it out frame for frame with AMDs 7970 just buy using a lucid performance mode. Don't laugh / Strangerthings have occurred.

The performance boost isn't as much from what I have heard, but yes a 560 Ti can probably compare with a 570 stock or 570 slightly OC with that tech enabled Something like 10-20% faster or so.

A boost from 200+ fps to 500+ fps... does what exactly?

 

[sm625]

The power density on the die has to be greater than any previous cpu.

I dont see the point in trying to dissipate more than 100 watts anyway. At somewhere around 4.4GHz, the increase in performance is negligible compared to the increase in power. That's just an estimate based on the trend of previous "sweet spots". Lynnfield is 3.8, sb is 4.1, so ib should be 4.4.

 

[Nemesis 1]

Well in a GPU benchmark test . Like hardware sites review GPU . You tell why this is important. I don't know you so . I can't tell what exactly your post means , But just guessing its not good.

LINK please . You got something to back up that statement scaling stops @ 4.4ghz

 

[psolord]

Nope, it's basically due to the Lucid Virtu MVP itself - http://www.lucidlogix.com/product-virtu-mvp.html

You have some food for thought good man. Thanks.

Nothing important or at least useful really.

Still our good friends at Anandtech have already posted an article regarding MVP.

The interesting bit is this.

Update: We had a chance to talk to Lucid about HyperFormance and Virtual Vsync in more detail, and have updated our article accordingly. One thing Lucid has made very clear is that while HyperFormance technically improves framerates, this is not the intention of the technology. Indeed it's largely a side effect of the fact that with HyperFormance the GPU is rendering some (or none) of a frame while still reporting to the CPU that the frame has been rendered and the buffers flipped.

That would explain why we get such speed increase in a high framerate benchmark/game, but I really cannot make heads or tales, as of why 3dmark11, which has lower than 60fps rendering in its scenes, still presented some considerable performance increase. I mean there shouldn't be any excess frames that could be discarded, since it was running below 60fps. :S

I never said that scaling stops. Wow what is with the reading comprehension today? I specifically said "the increase in performance is negligible compared to the increase in power". The scaling becomes more and more nonlinear.

On an i5-750, 3.7/3.8GHz is where the efficiency starts to really blow out, ie wattage goes parabolic. I cant find the same chart for the 2500k but I have seen one and it occurs at 4.1GHz.

What I want to know is where is this point on ib? I am assuming it is 4.4GHz.

So basically it drops frames to increase the speed a game can run at, and it adds the dropped frames to your fps so that you can brag about a bigger number that has no basis in reality. This looks about as useful as snake oil tbh.

The below 60 fps area is where I'm most interested in seeing what happens. The Techreport article covering the initial Virtu MVP introduction back in September actually had some impressions of the demonstrations, the most interesting of which is found about halfway down the page. Namely, what happens when you use this on the definition of underpowered hardware - the HD 3000 iGPU all by its lonesome. Their impression was that it provided a marked improvement, not necessarily by increasing the actual number of frames rendered, but instead by properly spacing them.

It sounds like if your hardware is capable of running over the refresh rate it drops the excess frames so that it can render the most up to date frame for each refresh and reduce input lag. Whereas if your hardware can't match the refresh rate it cuts out the extra frames and merely sends the card what it'll be capable of rendering, thereby making the best use of what little you have. In both cases it sounds like it'd use a feedback loop of sorts to know how long it takes a card to render a scene of certain complexity in order to guess which frames to send.

I may have read it wrong and listened to the tape hereing what I wanted . But as I understood it . It doesn't drop frames . But doesn't rerender all objects that are in another frame only rendering new objects . Thats as I understood it . But Like I said That could be me hearing and reading what I want to read or hear

been tested on z77 too

how cool are those bios icons :awe:

 

[Absolute0]

Pics got taken down, but had 6.1 Ghz IB on XS
http://www.xtremesystems.org/forums/showthread.php?279711-Ivy-3770K-amp-MSI-Z77A-GD65-LN2-results

IIRC it was 6.1 Ghz SP1M and 6Ghz 32M something like that. He reports 5 Ghz stable on air but 1.42v makes it only marginally better at OCing than SB.

 

[Tempered81]

That guys testing wasn't exactly idontcare quality stuff, I would wait for more reports or more detailed and competent testing before drawing any conclusions (even conclusions about the engineering sample, let alone retail).

Looks like they were not kidding you. Read his review, he says he got 5.2 on his 2600k, and couldn't get higher than 4.8 on his 3570k and 3770k due to heat on air.

[aaksheytalwar]

Does that mean Ivy might even mean a slight downgrade for some?

 

[Tempered81]

At stock 3770k is an upgrade to a 2700k. Overclocked max on air it's a tie 2700k @ 5ghz = 3770k @ 4.75ghz. Benching ln2 3770k is an upgrade.

The test was not done on air, it was done with a H100 with 2 fans and knowing that just made it worse. :\ Looks like I would have to get custom WC for some decent overclocking.

 

[pelov]

I think it depends on what you're looking for. If you were expecting a number-crunching stallion then IVB just doesn't have that kind of horsepower. If you want the HD4000 along with the superior compute ability and low power draw then it's an upgrade.

A lot of people forgot what IVB was intended for in the first place: maturation of 22nm along with graphics + mobile. If you're in the desktop crowd then you may be better off buying a [presumably] cheaper 2500K/2600K.

Personally I can't wait to see how IVB and Trinity stack up in the laptop segment This i3 sandy has been a beaut but it's lousy graphical performance and power draw have been a boon.

Bummer...although we are conflating terms here that will probably lead to confusion amongst readers.

Heat = power consumption.

The heat is actually lower. A 1500W electric heater is producing 1500W of heat regardless whether it operates at 500C or 200C.

The issue here is temperature (not heat) as it related to TJMax.

Yes heat, in combination with thermal dissipation/resistance, ultimately determines temperature, but there is a difference and that difference holds a meaningful distinction amongst many readers.

IB gets hot (temperature) but does not produce a lot of heat (power dissipation). The same could be said of a burning match (hot, but not much heat) or an incandescent light bulb (also very hot, but also no much heat dissipated).

No question this is why TJMax has been elevated for IB over SB.

The tradeoff is in intrinsic lifetime reliability (a deferred cost to the warranty program and risk management portfolio) versus diesize (an upfront cost and margin hit).

Regardless, the practical considerations for the overclocking enthusiast is that the search continues for ever better air-cooling HSF setups and water-cooling. That quest has always been there, for the same reasons.

I was surprised that I would need to go from my Tuniq tower to a NH-D14 just to keep the temps on my SB (NH-D14) the same as the temps on my Q6600 (Tuniq tower). But that is why the NH-D14 was invented.

IB will drive the development of nex-gen cooling solution, the cycle continues.

In the near term though, after my experiences with cooling SB, if I can get an IB I can tell you I would lap it immediately and I'd also use nothing less than Indigo Xtreme for the TIM if the operating temps were limiting my OC.

 

[pelov]

I think that the heat may be less of a problem on the desktop. On laptops the small size of the chips will cause some funky heat issues, much like what was seen with the Acer Kepler laptop review where it doesn't all get hot, but it gets really hot in a particular place.

Thats a pretty chart . Now get a chart for SB arch . See how it compares

I was hoping that someone would bring this up. So where you place your sensors in the die will give you differant heat out put readings is this not so? This is why AMD cpus appear to be running cooler than they actually are.I off course realize that some will say this is where SOI pays off. Luckily for us will shall see . As AMD switches to bulk strain

Well, I'm not sure about the differences in temp readings, but what I was getting at is that these smaller chips with very tiny nodes are packing a huge amount of transistors in a relatively small area, requiring some heavy cooling per-square-mm -- case in point, Ivy Bridge temp readings and IDC's point about TJmax. On the desktop this doesn't really matter all that much as you've got huge coolers and water cooling and you're not placing your keyboard essentially right on top of your CPU, but on laptops you might see what AT's review of Kepler saw where the laptop got really hot in a very specific place, most likely the GPU. If you need another example just have a look at the recent articles regarding the iPad3 and the warmer temperatures.

Small die sizes and billions of transistors are tons of fun until someone gets third degree burns

Ya on the experamental system I am building . I will employ everthing you mentioned here. The water block I will use on that system is a AquaComputer kryos high flow with silver base .I have used silver bases for along time but never this cheaply as having to by the silver and than have the machine work done is very expensive . All this for 3c. But I believe its needed on this system as I am using the AquaComputer 420 dual loop with only the 30% loop going to the cpu. We all ready know the cooling threw the loops will work perfectly as we use a patent mixer system before the Reservoir. It works great. I was also able to remove the very expensive flow control valves with pressure guages . The Kryos water block is pretty restrictive as is the 420 dual loop modular Rad . We have our MSI Z77 M/B already . But I have no ivy cpu . So we tested with SB and its very good results . I see no reason IB will change those results. Also IDC lapping is good . BUT . If its true that intel will replace for free the 3700K 1 time if you destroy it . I would be sure that lapping doesn't remove the 1 free replacement offer.
