The ASUS card behaves in 3DMark06 just as it did in 3DMark05, but has a lower overall score. It is the only card not to score less than 4000 points.
Having a lower core frequency than the ATI Radeon HD 2600 XT, the ASUS EAH2600PRO is far slower than the others in the SM2.0 tests but outperforms the GeForce 8600 GT in the SM3.0/HDR tests, confirming the superiority of ATI’s architecture at computationally complex tasks.
The results of the individual tests from the first group agree with what we’ve said above: the EAH2600PRO can’t do anything when the application puts a serious load on the graphics card’s texture and raster processors.
The second group of tests makes wide use of complex shaders, and the EAH2600PRO feels at ease here. It is limited in the first of the SM3.0/HDR tests by its low frequencies and small number of texture and raster processors, but in the second test it beats the GeForce 8600 GTS and the ATI Radeon X1950 Pro!
