Borderlands

It is remarkable that when antialiasing is off, the new Radeon HD 69xx cannot catch up with Nvidia GeForce GTX 570. However, as soon as MSAA 8x is enabled in the drivers, the victory goes to Radeon HD 6970, while GTX 570 can only compete against the Radeon HD 6950 (which is exactly what AMD has initially planned). Radeon HD 6970 is about 10-12% faster than Radeon HD 6950 and about 22-26% faster than Radeon HD 6870 in three test modes out of four. However, in the heaviest test mode when the resolution is set at 2560x1600 and antialiasing is enabled, the new HD 6970 gets up to 82% faster than its predecessor, HD 6870. It most likely owes this advantage to twice as much memory that all Cayman based graphics cards have. And we are going to come across the same situation again today.

Grand Theft Auto IV: Episodes from Liberty City

Here GeForce GTX 570 is the winner. All AMD based graphics accelerators demonstrate very similar results.

Left 4 Dead 2: The Sacrifice

Keeping in mind that the fps rate in this not very resource-demanding, but very popular game is relatively high, antialiasing is totally justified. And in this mode Radeon HD 6970 outperforms GeForce GTX 570 and Radeon HD 6950 runs just as fast as the Nvidia based solution. The senior Cayman based product is about 12-13% faster than the junior one, which, however, disappears completely if the junior model is overclocked. I also have to add that Radeon HD 6970 is 24-30% faster than HD 6870.

Metro 2033: The Last Refuge

This game didn’t reveal any leaders. All graphics cards are fairly slow here. I could only point out a decent performance gain of 24-36% that Radeon HD 6970 demonstrates over Radeon HD 6870.
