Considering that an HD5850 runs at ~80c with a 35% OC, one could assume an HD5870 would run just as hot with a 20% OC.

 
Here are results from the launch review of the 5850 at Hocp.
The 5870 hits almost 90 at STOCK
The 5850 82c STOCK

The prowess of ATI's 5 series keeps growing , xD
 


Wtf kind of logic is that?

So like 99% of the experiments on the planet are invalid? That makes total sense.
 


Maybe instead of just "refusing to believe" a stat from a review, you could provide some alternate data ? Your spouted off before about another site not being reputable as a comeback, heres a quote from the LAUNCH article for the ATI 5870.
This is VERY IMPORTANT . Guess What they said might be issues.

SOUND AND HEAT, lol : It goes full circle. I have no doubt the new Nvidia cards are louder, but ATI fanatics are exaggerating every detail of these cards .

But a pair of Radeon HD 5870s was the loudest combination in our tests, generating 54.7 decibels from our plucky little Extech 407768. These cards actually did hit 100 degrees C, at which point they’d throttle, dip back to 99, and then hop back up to 100. What you really need to be careful with in a closed case, though, is a rising ambient. The Radeon HD 5870’s decked-out bracket doesn’t have a full slot’s worth of ventilation anymore, so half of the card’s air actually blows out the top back into your chassis.

This was a reasonable statement made about the NEW 5 series cards. This same logic applies to Fermi, IMHO.
When you start talking about cutting edge graphics, you have to address heat and noise—the collateral damage of complex GPUs and high clock rates under the duress of synthetic 3D loads.
 
You can't use 2 separate reviews for comparing 2 different things (ie. here's a review of a GTX 480 and here's a review of an HD 5870, neither one having the other in it. The 480 got 80fps in some bench, and the 5870 got 400fps in the same game, therefore the 5870 is OBVIOUSLY vastly superior). And the same goes for heat/noise comparisons. If a chart doesn't have both cards, you can't draw conclusions that 88 degrees (ALMOST 90!!!!) is just BARELY under the 480's 93 degrees, because in the same situations (case, ambient temp, stressor, etc.) the temperatures for each could be off. You can't one-to-one them like that.

Yes, the HD 5870 is not the quietest/coolest card ever. Everyone knows that. But the plain and simple truth is: The GTX 480 takes significantly more power, (~40%) and gives off more heat, (~40%) and runs hotter, (few-several degrees) and is louder than the HD 5870. Whether or not this matters to you at all, completely up to you. Where the point of "too much" noise and heat is, is a totally personal thing, unless cards are actually, seriously dying before ~6 months.

Is that clear, yet?
 



the first part, i disagree with. as long as oyu are comparing reputable sites unbiased reviews, then the results are directly comparable. granted, they will be less accurate than direct becnhes, but you still get the same snapshot of overall performance of any given piece of hardware.

by relying on direct comparisons, you are severely limiting the pool of benchmarks to draw from, and likely getting a LESS thorough analysis.

the second part is spot on though, couldn't have said it better myself. thats the glaring issue here, if the heat/power draw of fermi is not an issue to you, then the 100 dollars for 15 percent more performance may seem perfectly reasonable. but the fact is, that issue is there. anyone who does take those things into consideration would see fermi as an awful choice when compared to the competition.
 



Please your reaching. Yes you can use temps posted in a launch review of a video card as representative results.
WTF are you thinking. Its a temperature. Obviously the ambient room temp might be different, but by how much ? Its a factual documented observation of the cards performance, heat output. I never compared it to any Nvidia card in ANY review by the way ? . Did you not comprehend that ?
 



While taking performance from 2 sites is a little more lenient, taking TEMPERATURE data from two different sources is a completely different story, and that's what they're arguing over. Temperature data has a LOT of variables outside the card, and is especially subject to different cases, ambient temps, cable management, sunlight, etc. So pulling temperatures should definitely only be done from a direct comparison. For performance, yes, you can take a decent picture from multiple sources. I probably shouldn't have used a performance example since I was focusing on the temperature argument.
 


a fair point, i guess thats true. i still tihnk though, that since there are so few direct comparisons that its still worth looking at multiple sources. even if you dont draw any conclusions from that data, it can at least give you an indication of the end result.
 




Running temperature and heat output are extremely different things. If you don't know that.... I don't know. But it hurts.

And while you didn't directly compare, you did say "OMG HD 5870 is ALMOST 90, which is ALMOST Fermi's 93!!! OMG OMG OMG"

Well, slight exaggeration.

And don't say I'm reaching, I just wanted to clear up that lack of reasoning knowledge that RealityRush had. It doesn't make any difference to me which card is better, I'm poor.

And please don't say I'm reaching, I just wanted to clear up the lack of reasoning RealityRush had. I don't care which card is better, outputs more heat, any of it. I'm poor, neither card makes ANY difference to me.
 



Yes, exactly. We need to test the GTX 480, 470 in Nvidia Fermi certified cases. With the patented wind tunnel cooling. That realistically is the only true way to test and document the results of the FASTEST gpu in the world. To do any less is like road testing a corvette on a wet race track. :)
 
True shadow, the fan is really low when the gpu is stressed, when using Furemark I let the fan @ 45% 5850@825Mhz and the temps tops at ~68C.
Fermis fan is way higher than 35%,up to 80% when it reaches 90C+, hence more noise. ATi had always low fan problem, maybe to make quiet cards, my old 4850 was reaching 88C while gaming and the fan would never pass 30% and back then there was no fan control at the release lmao already saw the card @ 105C. We cant trust Auto fan rofl
 

Then wouldn't that be AMD's fault for settings the pvm very low even under load they traded silence for heat. A HAF 922 is a sub 100 case 😀

I'm sure no one would argue that 5xxx are hotter then the 480's but the cards them selves could be hot just for the sake of not agressive enough cooling which is fine as long as it doesn't hurt the card also one can always bump up the fan speed using w.e ATI has to use.
 


Of course that is comparing two cards with 2 fans, where the single HD5870 was quieter and generated less heat than the GTX295 whose performance would be comparable and 2 HD5870 in Xfire would far outperform all other examples there the only thing close would be putting 2 of those GTX295s together as well or 3-4 of those GTX285s.

The issue is that GTX480 consumes more power while creating more noise & heat than the HD5970 which outperforms it.

Not quite the same thing as your example. :pfff:




AS long as you compare an HD5870 & HD5970 under the same conditions go ahead, but what you were doing before was comparing them under different conditions (ambient, case, other influencing parts), so not the same as your example again. To do so in your example would be like testing one on a wet track and the other in dry conditions. What you're proposing now is to test one on the home test track to get your 'fair' comparison.

I would think this is a pretty simple situation. Find the best case which is not specifically designed for one or the other camp (something that may have won case of the year in 2009 for example) and then test both under equal conditions. [:grahamlv:3]

Seems easy enough.
 
Wow, that's actually a disappointment. :??:

Everything I like about Xbit's typical review is missing. No card power draw, just system; and just a single soundcheck at a distance of 15cm (although the ramp through the RPMs instead of using it in day-day situations [which doesn't reflect use/gaming noise, just the noise of the assembly]). :mouais:

While the conclusion is similar to others, I'm disappointed that the methodology I had been hoping for is missing, and it still leaves me with a feeling of having an incomplete picture, as I don't have that extra little minutia we usually get. :mmmfff:
