The Test

For the 5700 series launch, AMD issued some new drivers as the previous 8.66 driver set did not include support for these cards. The driver set we used for these cards is 8.66.6, which is from the same branch as the earlier drivers. In our own testing, we haven’t seen any performance differences between these drivers and the previous ones on the 5800 series cards, but AMD did note that certain configurations might see a small performance boost. As such our results are still using the original 8.66 driver for the 4000 and 5800 series.

Also, as AMD sent us a pair of 5770s, we have tested these cards in a Crossfire configuration. This configuration is largely academic, as 2 5770s is just shy of the price of a 5870 and brings with it all of the limitations of multi-GPU scaling as compared to single-GPU scaling.

On a final note, our 5750 sample is a 1GB card.

    What in the world is going on with this game? 8800 GT beats the 4850? No, sorry, I don't buy that. Something is wrong here. The 5770 beats everything? If that is the case, then this game should immediately be removed from the bench suite - games in the bench suite should help us understand the general performance characteristics of the hardware and a game that returns such erratic results actually distorts that understanding.

    On page 13 you say:

    "The 3870 beats it by 14W at the cost of a significant degree of performance, while the 8800GT is neck-and-neck with the 4770, again with a decent-sized performance gap."

    You certainly meant 5770 there. But this brings me to a question: Why isnt the 4770 included here? As an owner of that card, I'm very much interested in the performance/power/noise difference - just ditch one of the relatively irrelevant SLI or CF combos. I dont think too many care about comparing high-end multi-GPU with performance parts such as the 5770 and 5750, even if its 57xx in CF.

    Ryan - thanks so much for the review. Nice job. It does seem like a 5750 Crossfire would be an interesting value - moreso than the 5770 since the latter is overpriced.

    And, Anand, I love your site, and don't take this personally, but, PLEASE GET A COMMENT SYSTEM THAT DOES NOT TOTALLY SUCK!

    PLEASE!

    AMD only sent out 1 5750, so I don't have a second one to Crossfire at this time. Reply

    It makes no sense (beside bad drivers) for the 5770 to lose to the 4850. The 5770 has more memory bandwidth (76.8) compared to the 4850 (63.55 gb/s), due to the 4850 sticking with ddr3, even with the 128 bit bus. The 5770 is also clocked 36% faster than the 4850 (850 vs 625).

    Yet the 5770 underpeforms the 4850 being almost tied?

    Maybe the 4*64bit memmory controlers on the perimeter of the chip keep up the data better than 2*64bit controlers with higher bandwith.
    I think that they could make it at least 192 bit (3*64bit).

    Actualy where the hell are the Cypress and Juniper die shots ?
    I cant find a single one on net.

    AMD is not releasing die shots. Reply

    Looks to me like AMD is trying to lure people into buying the remaining 48** cards. Once the old chips are cleared, the price of 57** will no doubt drop. Reply

    What really has me concerned is how the 5870 is scaling in these tests.

    The 5870 core is essentially two 5770s strapped together, and you would hope scaling would be near linear. When two 5770s in crossfire match or even beat a 5870 I'm left scratching my head.

    Somewhere there is a significant bottleneck in the 5870's design, and I'm wondering where that is. Anyone have any clue?

    Hopefully a driver update will fix these issues, because if not there is a lot of wasted silicon on each of these chips...
