AMD’s Radeon HD 6870 & 6850: Renewing Competition in the Mid-Range Market
by Ryan Smith on October 21, 2010 10:08 PM ESTUbisoft’s 2008 aerial action game is one of the less demanding games in our benchmark suite, particularly for the latest generation of cards. However it’s fairly unique in that it’s one of the few flying games of any kind that comes with a proper benchmark.
Unlike our previous shader-bound games, HAWX is a game that’s light on the shaders and comparatively heavier on geometry, texturing, and general rasterization. As a result it’s one of the best games for the Barts architecture, as the 6800 series comes out only a frame behind their 5800 series counterparts thanks to the equal number of ROPs and the higher clockspeeds of the 6800 series. In this game at least, 6800 and 5800 are equals.
Unfortunately for AMD, both generations may be equal, but compared to NVIDIA they’re equally slow. The EVGA GTX 460 and the GTX 470 enjoy a healthy 10% lead over the 5870/6870, while the 6850 has more in common with the GTX 460 768MB than it does the GTX 460 1GB.
Meanwhile in an action that blows our mind, the 6800 series cards in Crossfire manage to convincingly beat the 5800 series in Crossfire. Admittedly we’re talking about a difference that’s academic (169fps vs 154fps) but it’s as clear a sign as any that something special is going on with the 6800 series in Crossfire.

The problem with that is that GPUs are much more complex than the way a single score can paint. The technology is complex and thus explaining performance across the board is also complex. It very much is the nature of the beast.The only way to go is to scour the web for reviews of the videocards that you are looking at specifically and for the applications you would like to run. It is still true though, that a 5870 will outperform a 5850 or a 5770 so they made that simple.
AMD definitely has ruined the simple 5850 5870 5890 nomenclature though...

I think if they just named it 6850/6830 instead of 6870/6850 they could have saved themselves a lot of negative sentiment.Sparks_IT - Thursday, October 21, 2010 - link
Any information on Eyefinity. I thought there was to be an update/improvement? And is an active adapter still needed?Jansen - Thursday, October 21, 2010 - link
There are connections for 2 mini DisplayPort, 1 HDMI 1.4a, and 2 DVI.http://www.dailytech.com/Radeon+6800+Series+Launch...
There are some pretty cheap mini-DP adapters out now.

My point should have been that you can now use 4 monitors natively with a single card.Stuka87 - Friday, October 22, 2010 - link
Actually its still limited to two displays at once as I recall. It has four interfaces, but they cannot function simultaneously.mino - Friday, October 22, 2010 - link
4 it is.DP interfaces are independent from DVI/HDMI ones.
So yeas, you can use any 2 of the DVI-DVI-HDMI plus those 2 DP interfaces.

No way, that's not how Eyefinity worksEyefinity allows 3 monitors to be driven by a single card, I don't think they would make it any less with the new cards. It may not be 4, but 3 should be alright

Ahh yeah, you are right. For some reason that bit of detail was not in mind at the time that I posted. Guess thats what I get for responding so late at night :)ninjaquick - Monday, October 25, 2010 - link
Actually, Barts can push 6 screens... As could cypress but it was crippled to three most of the time, with the exception being eyefinity series cards that had 6 DP on the back.
