XFX HD7770 Black Edition S Crossfire & HD7750 DD Review

We normally use the Sapphire TriXX overclocking software for our reviews, but this launch was slightly rushed and Sapphire didn’t have a version ready to support the HD7770 when we started these tests. We therefore reverted to AMD’s Catalyst Control Center.


The XFX HD7750 could be overclocked to 875mhz core and 1230mhz memory, translating to a 9.3% increase on both core and memory speeds. The HD7770 Black Edition overclocked by 70mhz to 1190mhz, and the memory was pretty much maxed at the ‘out of the box’ settings.

We didn’t include results from these overclocks as the differences in the real world were negligible.

    great looking cards. still a bit costly for what you get I think. Crossfire any better than it was a few years ago? nothing worked when I had two cards. (well worked the way it should have). That is why I moved to nvidia.

    I wasnt impressed. but I can see the merit with two of them in Crosfire.

    Have to ask. Would the people buying one of these really be able to afford two?

    This is why crossfire makes sense. Obviously we have the rich guys who buy two high end boards to break benchmark scores, but back in the real world. you buy one, use it for a while, save up. then get another. you have high end card power for less money with less initial outlay.

    First time ive seen a company sell a bundle, with two in it. with two free games those cards work out at £135. its not bad value considering.
