****Official 6850/6870 Reviews thread****

Going by anandtechs review the EVGA *** 460 is on par with a 6870 " better in games like Dirt 2 " now with the 6870 not clocking very well would it not be best for people that are willing to overclock to go for the cheaper 460 and clock it.
 
Due to being limited to Crossfire, my options are either to get another 5850 (if the prices drop), or sell up and get 2x 6850.

I know the 6850 is a much weaker card, but if the scaling on the 6850s is as early reports say, they could match 2 5850s for £40 less.

Please let me know what you do :D

I might be getting two 5850's and I have the same power supply as you so I just want to know if it can handle 2 5850's ;)

All you guys saying you can get 6870 for under £180, do these places actually have stock though?

Not as far as I can see.

Might I also remind you competitor talk is against the rules on this forum. (Thats aimed at those hinting at pricing elsewhere, in stock or not).

Depends on what the rest of your system is.

I did some total system power draw tests when I sold my 5770s.

5770 crossfire idle = 145w
5770 crossfire load = 310w - 27/74/51 - 71ºC
5770 single idle = 135w
5770 single load = 220w (90w per card) - 22/37/26 - 63ºC
5850 idle = 150w
5850 load = 270w (140w per card) - 40/68/48 - 70ºC
5850 775/1100 load = 275w - 43/72/51 - 72ºC

So banging another 5850 in there would take me up to 410w at load, plenty of headroom for a 520w PSU. :)

Will need some molex-PCIE adaptors though.

I have a 965 BE processor and that uses a bit of power but I am not going to overclock it :P but I have less hard drives though :)

Will just have to wait and see won't I. :)

lol there is a ton of reviews in the first post.:p

They are about on par.

:o

"And at the same time it draws less power and produces less noise than the GTX 460 1GB. In fact unless the GTX 460 1GB was cheaper than the 6850, we really can’t come up with a reason to buy it."
 
Scaling looks good on CF 68xx. Wonder if it's anything to do with the 10.10 drivers? Are owners of 58xx CF setups going to see a performance boost?

It overclocks real good, 850 core matches and in some games beats the highly clocked 6870.

There are very quiet 460's out there.
 
I'm rather tempted to swap out my 5770 for a 6870. I can never justify buying the ultra high end face melting GPU's, and always limit myself to sub 200 notes... For that it looks quite good for the cash.
 
My take on it is that looking at just the performance here is misleading. The 6850 & 6870 aren't designed to win a performance war, they are designed to win a price war and are very suited to that purpose. They have amazingly small chips, are pin-compatible with Cypress (little board R&D, re-tooling or stock write-off cost) while being more-or-less competetive with all of Nvidia's offerings in the segment.

AMD have much more scope for dropping prices that Nvidia, who currently appear to have brought a knife to a gunfight, and judging prices at launch seems a bit pre-emptive to me. IMO AMD will have wanted to avoid the the pricing problems they had with Cypress, it's better to start high and drop the price than the other way around.
