BIG BANG: HD 5970, HD 5870 CrossFireX, HD 5850 CrossFireX (english version)
We are afraid we have to start the review with explanation. As we mentioned, we wanted to start a GeForce GTX 295 in the competition, it arrived to the HOC HQ, but the outputs could not give picture to the display, so it will not showed in the graph of course. There will be only one GeForce –- just by piquancy — ASUS Matrix GTX 285. The other problem was provided by Catalyst 10.1 driver, what (most of the time) worked very well, but when we arrived to the HD 5870 CrossfireX, it was going to be rubbish, the feared gray-dead showed its face many times, and a lot of test could not give result. The Catalyst 10.1 Hotfix announced in the mean time, but it could not help. We did not see the gray-dead again, but a couple test froze out or stepped out. So where you can find null value, we did not get result because of the driver’s problem.
The first is the 3DMark Vantage, it simple could not run the test with variations of HD 5870 CF, but there was no problem with other cards. HD 5850 pass GTX 285 with hairbreadth, but HD 5870 stretch oneself out a little of them. HD 5970 was better than HD 5850 CF, but it was not lot.
Also the Heaven did not like the HD 5870 CF, and we did not see sense to perform DX10 GTX 285, because Radeons support totally other settings. The power relations between the knockaround guys showed well, 5970 HD was able to stand onto the edge directed behind HD 5850 CF again.
Graphs of DirectComputer are interesting. GTX 285 supports the older version and ran in DX10 mode, so it was got behind the red cards (which are black nowadays). Systems which are from identical GPUs was in the same line, so it is clear the program cannot profit from the presence of second GPU.
