In this review we will put the dual card CrossFire configuration of the AMD Radeon HD 6870 in the spotlight. It promises higher performance than a Radeon HD 5970 at only a fraction of the price. But is this enough to make CF a recommendation?

Yikes. The scaling is not too great. Ill keep my 4890s for a while. Power consumption isnt bad though. Good review Wiz. Could have used some Crossfire 5850, 5870, and SLI 460, 470, and 480 for some extra comparison.

I wonder why this review and Guru3D's crossfire review are in stark contrast of each other. Must investigate...after dinner!

Knew that already. They're using an i7 965 @ 3.75GHz with 6GB of 1500MHz RAM. Very similar systems actually.

AHA! They used Catalyst 10.10, while W1zz used Catalyst 10.7. Maybe 10.10 gives much better crossfire scaling performance.

W1zz, any chance you could do a quick test on 10.10 for a 5870 Crossfire to see if it has improved?

I know, I'm glad I stuck with my 5850s..They both perform as well as one 5970. Next month we will see the 69xx series ..those are the ones I am really waiting for. I plan on buying a pair early next year

Well at a tiny rez all cards rule, but till you up the res these gpu's shine... Put it this way.... An engine can only pump out the demand for power.

put a load on these cards and watch the performance show what they can do. :eek:

I meant in scaling... as in in a certain game that you already get 110fps, don't be surprised to get 140fps only... but when you on get 39fps, these beasts can get you 76 fps

Alright now lets just calm down now..

Your inner fanboy is being unleashed heavily.:ohwell:

Definitely some good scaling in some games, but lacking in some others.

but they lack only in high fps games (ie: ow res and/or low demanding games), so who cares! look at 1920x1200 where most ppl will be using these cards... look at metro 2033 and crysis etc... practically 100%, about 90+%

just incredible IMO

now start comparing its not the newest but its the quickest way to get a estimate
so they can see faster

Wait, a 5870 CF under a 5970? not that helpful lol

but by doing 5870 CF / 5870 normal from the first and multiplying that by the 5870 on the 2nd gives 48.847, or to round up, 48.9 fps for the 5870 CF
