We start with the results of Futuremark's benchmarks. These include the results of the 3DMark 05, 3DMark 06, 3DMark Vantage and the 3D Mark 11 tests.
Starting with the 3D Mark 05 benchmark, the Club3D HD 6950 1GB got just 17447 points, which is very high for a $250 card:
At the 3DMark 06 benchmark the Club3D HD 6950 1GB scored an impressive 17447, which is higher than the score of a GTX 580 OC ! Of course, this does not mean that the cards are comparable in terms of gaming performance. The HD 6950 also ranked higher than the HD 5770 and the Nvidia's GTX 460, GTX 465 and GTX 470 GPUs:
The 3DMark Vantage tests the performance of each card in different resolutions. We charted the GTX 460 1GB OC, the GTX 460 768MB, the GTX 470 and the GTX 580 OC and the HD5770 graphics cards.
The Club3D HD 6950 1GB performed decently to this benchmark. The card gave relatively low scores at 1280 x 1024 but it actually showed its strength at 1920 x 1200, where it ranked second after the GTX 580 OC:
Below you see the results of the recently released 3D Mark 11 v1.00 benchmark. The Club3D HD 6950 1GB is again more powerful than the GTX 460 1GB OC:
