Heat And Noise
Heat and noise output are controlled not just by the GPU voltage and clock, but by the cooler design. Asus surprised us by having the lowest temperature, since the card was also relatively quiet. Sapphire takes second place when its fan is turned to max speed.
Quiet coolers are often sub-par when dealing with heat, but Asus proved the contrary with its DirectCU design. The chart below is not perfectly accurate, since some background noise was unavoidable.
Sapphire has the noisiest card. But looking beyond the card itself, there is an advantage to its noisier, blower-type fan. That advantage is case cooling, since the Sapphire Toxic 6850 is the only card in today’s comparison to vent most of its heat outside of the case. We’ve previously seen the consequences of using internally-vented cards in an extreme CPU configuration.
Following a similar method to that of our previous-page’s energy efficiency calculations, we compared temperature to noise for today’s cards. Note that the temperature division is “flipped over” in this case to give the lowest temperature the highest score, and that the “acoustic efficiency” chart does not account for performance differences.

It would be nice to see overclocking results. I know the whole "results will vary" malarkey but still, it would be interesting to see things like the benefit (if any) to having two pci-e power connectors on the Sapphire card or how high you could take the ASUS card using the software that came with it. Oh, and also, can you use Afterburner with the Powercolor and Sapphire cards?

I use afterburner with a Gigabyte Card, (Flashed to ASUS). Works fine.

Yes

"Now, here did I put that Christmas list?"
here = where
Why are you using catalyst 10.6 (drivers from june) instead of latest, quite long already available 10.11 or 10.10-beta with HD6800 support?
love this card looking to buy it for my new build and would go for ASUS as i already own the game.
No OCing?
so, wheres the comparison between these cards and rival cards from nvidia??? using recent drivers?? and OC???!this doesnt really tell us anything except the performance is so close you may as well get the cheapest of the lot.
ATI driver support is a complete debacle. That's why this article uses stone age drivers (10.6)

The previous article, which answered all your questions a month ago, was linked numerous times in this article.
So, it seems it can run Crysis!
I always appreciate more information, but shouldn't an exploration of the top options in the $200 range be more appropriate given it's the Christmas hardware giving season? The 6850 is a great card, but a more focused value study across many makes and models might be more useful. All the same, I'll take what I can get. I'd just like to point out that the new Radeons are getting more expensive while nVidia's 460s are getting much cheaper.
Just my two cents, but that would seem like a much more interesting article. We already know the 6850 is mostly quiet and pretty efficient, but GTX470s are going for only a few dollars more in some cases. Bring the throwdown.
Excellent conclusion, Thomas. Explores different uses.
You can use Sapphire Trixx to overclock and unlock the voltage for the new Radeon 6800 series cards if Afterburner doesn't work.
I would have loved to see the Sapphires being OC'd and then XFire'd. Will there be any love for that? 8)
Great article also, thanks Mr. Thomas!
Cheers!

Thanks, I don't think I could have ever figured that one out...
Those dirt2 benches kinda make me regret getting the 6870. Oh well...
What I like about the 6800s is that AA does not detract that much from framerate.
A nice review and round-up of the 6850, Thanks Tom. I have to say I was am still am very interested in the 6850-70 model GPU's and I am glad to see some comparisons of the 6850's. Although right now these cards exceed my spending limit, I am glad to say I picked up a 5830 for $130 after MIR(pricing mistake?), I think thats a good trade off of price/performance for now.
this article was pointless
overclocked cards perform better and use more power.. we all know this
