Graphics Card Ranking (5th Time And Last) (Updated Daily) - Page 88

post #871 of 909
the radeon hd5570 i think does not support crossfire . you are better off with a new radeon hd6670 gddr5 for the time being until you build a new pc next year. in case you build yourself an amd trinity based system then you can also use your 6670 in that pc as well in crossfire mode with onboard gpu. so go with hd6670 gddr5 thumb.gif

I got a 1gb Sapphire HD 5570 card and I want a cheap upgrade while I wait for the opportunity of building a new PC from scratch next year. I'm thinking about setting up crossfire or simply switching to another card, but I can't find many comparisons on the web of this card in CF against single better cards, so I turn to you =). Here are my upgrade options:

  • Crossfire with another 1gb Sapphire HD 5570
  • Crossfire with a 2gb ATI HD 5670
  • Switching to 2gb XFX HD 6670

I'm new here so I hope I'm not asking too much, but I'd like to know how would my options weigh against each other, no big explanation, just which is better and which is worse. Oh and can I crossfire 2 compatible cards of different brands (Sapphire and XFX, for example). Thanks in advance.
Yes, the HD5570 supports Crossfire. Often low end cards don't need a Crossfire bridge which you can misunderstand as not supporting Crossfire. The brand does't matter, they just have to have the same GPU. Here is a review from Tweak Town that compares Crossfire HD5570, single HD5570, and HD5670:

A single HD6670 GDDR5 would be a good option as then you wouldn't have any Crossfire hassle for whether it works for the games you play. It seems that Crossfire HD5570 performs pretty good so if a second one is cheap enough it's definitely an option.

Thanks, that review helped. I got a couple follow ups, though. All the cards I have access to have GDDR3 memory, not GDDR5, so I'm thinking of going the crossfire way since it seems to give good results. But, should I get the HD 5670 or is that potentialy more troublesome to be worth it? Than setting it up with the same card I got (HD 5570), I mean.

I mainly want it to play the new World of Warcraft expansion, and I've read that game works with crossfired cards. I'm assuming GDDR3 HD 6670 is clearly below the other options but if it isn't I could use the heads ups there too tongue.gif

I would stick with the HD5570 for the second card. Like dual channel RAM configs, with Crossfire it's best to get close to identical cards for the best results (when it comes to core and memory clock), as the setup will be limited by the slowest card. I would guess the HD5670 might work as both use the same GPU except the HD5570 is clocked lower and has only GDDR3 memory, but I can't confirm that. If the HD5670 and HD6670 you have available to you are the GDDR3 versions then they don't have much appeal.

Thanks a lot. I'll stick with the HD 5570 which is also the cheaper (they're all pretty close in price though). You were very helpful!

It was my pleasure and I am glad you found the info helpful. If you have any other questions let us know.

would it be a bad Idea to suggest amd and intel onboard graphics? Maybe starting with sandy/ivy and the amd fm1 socket? Just an idea biggrin.gif

This is my go to guide for suggesting lower end graghics to friends and wish those were on there too

Thanks to the performance improvement in Catalyst 12.11 I can finally get the new GPU chart out. On the GTX650 Ti release there were so many cards close that is was basically impossible to place them since Nvidia released big performance improvements with the GTX650 Ti release drivers. The relative performance data was taken from TechPowerUp's AMD Catalyst 12.11 Performance Analysis article. Changes to the chart include addition of the GTX650 Ti, adding a 1GB option to the HD7850, updating the relative performance data, and minor changes to the location of the brand logos. Here is the new chart:

the list needs to be updates as its misleading others to think that its possible to quad fire 7750 when AMD says its not possible considering they say only the 7970 and 7950 support quad gpu
