AMD’s Radeon HD 6870 & 6850: Renewing Competition in the Mid-Range Market
by Ryan Smith on October 21, 2010 10:08 PM ESTElectronic Arts’ space-faring RPG is our Unreal Engine 3 game. While it doesn’t have a built in benchmark, it does let us force anti-aliasing through driver control panels, giving us a better idea of UE3’s performance at higher quality settings. Since we can’t use a recording/benchmark in ME2, we use FRAPS to record a short run.
Mass Effect 2 ends up being another game that AMD that AMD struggles at. It’s not a game we’d normally classify as being shader-bound, but looking at the 6800 series performance relative to the 5800 series, it’s either that or texture-bound. In any case the 6850 is still competitive with the GTX 460 1GB, but the 6870 falls behind NVIDIA’s competing cards by several frames per second.
Meanwhile it’s interesting to note that this is the only game where the 6800 series doesn’t dig itself out of a hole in CF mode. Both the 6850CF and 6870CF are where we’d expect them to be relative to the 5870CF/5850CF if we took a simple extrapolation of their performance.

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.
