The graphics cards are listed in the diagrams in the order of descending retail price:
- Radeon HD 7850 2 GB – starting at $249;
- Radeon HD 6870 1 GB – starting at $179;
- Radeon HD 7770 1 GB – starting at $159;
- GeForce GTX 560 1 GB – starting at $159;
- Radeon HD 7750 1 GB – starting at $109;
- Radeon HD 6770 1 GB – starting at $109.
The Cape Verde based cards are far from impressive in our first semi-synthetic benchmark. The Radeon HD 7750 is hardly any faster than the HD 6770 which costs the same money whereas the Radeon HD 7770 GHz Edition is routed by the GeForce GTX 560 which can be bought for the same recommended $159. Overclocking doesn’t help: the 128-bit bus prevents the high-frequency Radeon HD 7770 from beating the Radeon HD 6870.
The overall picture is the same as in the previous version of 3DMark.
Unigine Heaven Demo
The new cards from AMD look more confident in this tech demo.
They are ahead of the previous-generation Radeon HD 6770 and (with the help of overclocking) of the HD 6870. The Radeon HD 7770 GHz Edition can’t beat the GeForce GTX 560 even when overclocked, though.
S.T.A.L.K.E.R.: Call of Pripyat
The first game on our list doesn’t contradict 3DMark except that the overclocked Radeon HD 7770 can beat the GeForce GTX 560.
Left 4 Dead 2
This game produces a different picture:
The Radeon HD 7770 GHz Edition falls far behind the GeForce GTX 560 whereas the HD 7750 can’t beat the HD 6770.
Metro 2033: The Last Refuge
Although we don’t use the maximum visual quality settings here, the new cards are awfully slow in Metro 2033: The Last Refuge. There’s nothing new in terms of how the new AMD cards compare with their opponents.
