AMD HD7770 Review
Now for the sake of direct comparisons our testing is the same as it always is. However we're aware that this card isn't designed to go up against a lot of the cards in our graphs, so we wondered if the latest HD7770 had enough new features to make it a worthwhile purchase. To this end we dug out our long-past reviews of the low-end Radeon cards, and saw how they stacked up in 3D Mark.
It's worth noting that the other four cards were tested on a 4GHz i7-950, rather than the 4.6GHz HexCore all-singing X79 rig we're using today. Finally, the other four cards are all available for around £100 rather than the £130 that the HD7770 is rumoured to retail at.
3D Mark 11
Even with the underlying benefits of a better test system and more modern drivers, the HD7770 barely keeps up with a HD6790 and is decimated by the HD6850 and plain GTX560.
3D Mark Vantage
In Vantage it makes a better fist of things, but once again it's worth noting that the other cards were tested on the PhysX heavy version of Vantage, rather than the patched version which moves PhysX to the CPU. So given the extra CPU power available from the i7-3960X it's not a great surprise that the HD7770 just edges ahead of its Radeon rivals. All in all if you're going for pure gaming performance, you can do better at a cheaper price with the older cards.
