The 7500 has no vertex shader, 2 pixel shaders, 6 texture mapping units, 2 render output units, or 0:2:6:2, my 9250 has 1:4:4:4 and my 9800Pro 4:8:8:8 piping according to: http://en.wikipedia.org/wiki/Comparison_of_ATI_Graphics_Processing_Units > > Also glxgears gives me 1400 fps in current setting small window > > full screen it gives me 300, this is with 16 bit depth > > with 32bit it gave me > > 1240 fps in its default window and 170 in full screen > > Please note that glxgears is in no ways a benchmark!
