Riva 3D heeft een review gepost waarin de 3D performance van de K6-3 en K6-3 met TNT2 en Voodoo3 met elkaar vergeleken worden. Hier een stuk over de QII benchmarks:
Unfortunately, I was unable to test the 3D NOW! enhanced 3DFX mini GL as it appears that it breaks when running under the V3, so I had to resort to running the normal 3DFX mini GL. Consequently, I also ran the regular OpenGL driver for the TNT-2, as opposed to the 3D NOW! OpenGL provided by AMD. What these scores show is that the K6-3 runs 20-25% faster than a K6-2. A very nice speed increase indeed. I'm very anxious to see what the numbers will be with 3D NOW! enhanced drivers.
