The first of the 28nm generation.
For testing the ASUS HD 7970, I used the following testbed.
As you can see I haven’t used a standard GTX 580 which costs $499, but the slightly overclocked Zotac GXT 580 AMP! Edition graphics card. The GTX 580 AMP! Edition runs at speeds of 815MHz/1025MHz compared to 772MHz/1002MHz default. The 6% increase in core clock and 2% increase in memory clock speeds come at a 4% increase in price hike; as fair a competitor to the HD 7970 as it gets from the Nvidia camp, without going overboard on price.
The drivers used for the Zotac GTX 580 AMP! Edition were Nvidia’s beta 290.53 and AMD’s beta RC11 (8.921.2) drivers.
As for the various synthetic tests and game benchmarks used, the below table provides details on the settings used.
All of the above tests were run at a resolution of 1920 x 1200, with all DX11 effects enabled, or set the highest wherever applicable.
