Table 3 shows that (1) At 1600x1200x32bit, the condition that 3D performance is limited by video memory bandwidth, only 69% fill rate of GeForce3 video processor brings into play. Without the memory bandwidth limitation, a GeForce3 will have a 104 fps performance. (2) At 800x600x32bit, the condition that 3D performance is limited by CPU, only 45% fill rate of GeForce3 video processor brings into play. Without the CPU limitation, a GeForce3 will have a 308 fps performance. Table 5 shows performances of the overclocked GeForce3. At 1600x1200x32bit, a GeForce3 has a 72 fps performance, while the GeForce3 with video memory overclocked will have as high as 80% of its fill rate brings into play and hence has a 83 fps performance. here
