Ivy Bridge vs Haswell

[SickBeast]

Personally I'm not interested in more cores, and I'm also not so much interested in having a laptop CPU in my desktop (sub-95W).

If AMD and Nvidia can figure out a way to cool >300W GPU's then I'm ready for Intel and AMD to open up a product lineup that goes there too.

And do it the good old fashion way, keep it to 4-6 cores and just give me some nice high clockspeeds. With configurable TDP, if I don't want 300W then I can set it to 95W and have the clockspeed throttle itself accordingly.

Intel would probably charge you $1000 for the privilege when you are already pretty much doing the same thing on your own.

What would be great is if Intel or AMD would release the tools that they use to validate CPUs.

IME running LinX, Orthos, and memtest at the same time is a pretty good stability test.

thats not right,my 2600k at 5.1ghz with 8 threads and avx is about 136 W are you measuring total system power draw?

This is with 1.55 v core and its stable at 5.3ghz at this voltage

No, that's CPU power I am referring to.

You must have a rather magical 2600K if your power consumption at 5.1GHz and 1.55V is a mere 136W. How did you measure this value?

there is no way your chip is pulling 270 watts.you are not reading it right.I have measured with 3 diffrent programs and even the one that came with the board.

do you know how impossible it would be to cool a 270watt cpu?

I held my stock heatsink on at stock speed and voltages with no fan just to see if it could post and the heat sink got so hot after a min(60c in bios)that I couldnt even hold it anymore.

270 watts would melt ever pin on your socket.

I'm having a real hard time taking you serious here.

First, the CPU can't exceed 98°C because it throttles itself. Whether dissipating 10W or 1000W, the temp won't exceed 98°C.

Second, if you read the thread then you'll have noticed how I measured the power-consumption. You have yet to state anything that invalidates the method of measuring power. Feel free to do so at your leisure.

Third, you have yet to elucidate your own methods of measuring your claimed 136W power consumption at 5.1GHz and 1.55V. You used a software program? You know they don't work, right? That's a "wow, just wow" moment right there.

You can neither deftly argue against my results nor can you deftly defend your own unsubstantiated claims of power-consumption. Which leaves me where I started this post, having a difficult time taking you seriously.

Iv taken my cpu up to the point where it throttles and it only drops 150-200mhz and hovers back and forth going from 97-98c.

You dont get it,you cooler will not cool 270 watts,your whole system would melt.Try using the software that came with your board to measure the actual watts for just the cpu.I think where you pulled your power was total system power or not a true reading.

the way I pulled my numbers I tried stock cpu and volts and it comes up at 80-85 watts and thats really close to the 95watt the chip is rated at.why dont you clock that chip to stock volts and clocks and measure what your readings are the same way you got your 270 reading.

if you are over 95 there is something wrong.

the sandy e's are adding 2 more cores with millions more transistors and its only drawing 30 more watts over a quad core,how is your chip pulling more than twice as much power as a sandy E and almost 3x more power than a 10 core 5000 dollare sandy xeon chip.

do you really think your 800mhz is pulling more currant than a stock clocked 10 core sandy xeon?

I have 3 radiators,chilled water,water wetter and 6 fans blowing on my board and it still hits 80c at only 135 watts,at 270 with no throttling my cooling would hit over 200c.There is no way a corsair water setup can cool 270 watts and keep your temps under throttling

wait are you saying the software that came with my 370 dollar board dont work? I have also tested the same chips I had on a ud7 board that was north of 350 and there software showed the same results.

 

[grkM3]

Here is a full system power draw with a gtx580.toms hardware got 25X watts for full system draw of an overclocked 2600k to 4.6ghz,how is your chip pulling 270watts on its own? at stock it pulls 166 watts total system power running prime 95.over at toms hardware he benched it running programs that would use cpu and gpu and hit max total power draw at 250watts at 4.6ghz

And here I was thinking my ~150W i7 920 is adequately cooled at ~60C with a Mugen 2.

There is no such thing as a 10 core Sandy Bridge Xeon.

If history suggests, Intel Tocks are underwhelming compared to their Ticks.

dude get a grip on reality. Guess what? some GPU's have been 300w+ for a few years now from both ATI and Nvidia and we are able to cool them with heatsinks that are smaller than the biggest CPU air coolers. Cooling 300w is possible.

As for suggesting using software to measure power use, well you are a nutjob if you think thats accurate, its been proven inneffective so many times its not funny anymore.

You are doing it wrong.

Read IDC's threads on sandy overclocking power consumption. His numbers aren't perfect, but they are rational estimates. Then read is thread on cooling, comparing his two coolers. You will learn a few things from this experience about cpu power consumption with overclocking.

Also, you really are doing something wrong if all that watercooling hardware can't keep a sandy cool. Consider posting a thread in Cases and Cooling with pics asking for help. There has to be something wrong.

 

[grkM3]

When did I say gpus don't draw 300 watts?we are talking about sandy bridge cpu.there is no way a sandy b chip is pulling 270 watts on its own.look at the site I posted.

And if you think my cooling is bad id like to see you run 1.6 volts into your chip and see where your temps are full load at 5.3 ghz.

Really

I would invest in a few meters and take the time to learn.
Never ever trust the outdated software that comes with your mb.

Correct. There's a 10 core Xeon E7 based on the Westmere-EX core.

I put in only the cpu 2600k @ 5300 with 1.6vcc cpu = 263 watts
This is old software

Maybe you should check to see if Consumer Reports® has a cpu forum. That might be more on your level.

[grkM3]

I think its sad that some of you people really have no clue.Go read the review at toms hardware.his setup pulled max TOTAL system power running games and cpu stress programs and the max total system power draw at 4.6 ghz was 25X watts and that was with fans,Hardrives and video card.

There are many more reviews out there that show the same results.

why dosnt IDK run his chip at stock setting and read the watts its pulling the way he tested his chip with the 270 watt reading?

I will bet anything its over its tdp

 

[grkM3]

Here you go,right from anandtechs own review.

stock 2600k pulls 86watts and 111 watts at 4.4ghz running cinbench.

going from 3.4ghz to 4.4ghz only brought up power usage by 25 watts,why do you people think sandy chips overclock so well on air cooling?its because they dont put out much heat and are very power efficient.there stock cooler couldnt even keep an old p3 cool enough to not shut down,the cooler is tiny but yet it does a fine job of even getting the chips to hit 4.4-4.6 ghz on the stock cooler.

If you spent more time reading the link I already gave you, and less time arguing with everyone under the sun, you would have noticed I already posted those numbers weeks ago:

At 2.0GHz clocks, with the Vcc reduced to 0.822V (IBT stable), the 2600K consumes 24W at 38°C under load with IBT.

At 3.4GHz stock clocks, with the Vcc reduced to 1.038V (IBT stable), my 2600K consumes 65W at 48°C under load with IBT.

Pushing it up to 5.0GHz, with the Vcc set to 1.488V (IBT stable), this 2600K consumes 227W at 93°C under load with IBT.

 

[LOL_Wut_Axel]

I'm hoping in the next few months we get so see some more info regarding Haswell. I'm hoping they'll finally bring six-core CPUs down to the Performance market. We've been stuck with $250-350 quad-cores for WAY too long. The legend [Q6600] was released in 2006, five years ago. We need to move on.

 

[grkM3]

Ok so now its 227w a little better than the 270w you said in this thread it pulls at 5 ghz.

you might have a llc or pll voltage set high for it to pull that many watts,I will hook up a meter to my atx 12v line and ill give you my computer if it pulls anywhere near 227 or like you first said in this thread 270 watts.

Ill post up a video in a few days,just ordered a ac power meter where Ill plug the computer into it and see total power draw at 5ghz etc.

I know the software is not 100% spot on but its not 150 watts off

Surely you are aware of the fact that your 2600K receives power through more than just the 12V line...

I wouldnt be so sure, since he still thinks software measureing is effective.
