NVIDIA Quadro FX 4500 X2 vs Quadro FX 4600 SDI
Theoretical performance comparison
Each GPU has several essential theoretical parameters that affect real-world game, 3D graphics and compute performance. These are texture fillrate, pixel fillrate, memory bandwidth, single-precision performance and double-precision performance. Below we explain why these characteristics are important and which card has better specs.
Pixel fill rate (gigapixels/s)
20 16 12 8 4 0 |
|||||
| |||||
Higher is better
The NVIDIA Quadro FX 4500 X2 has higher pixel fill rate due to greater number of ROPs (Raster Operations Pipelines), even though its graphics clock is slower. Having better pixel fillrate allows the graphics card to draw more pixels on screen and off screen, which is beneficial for some 3D effects in games, or when playing at higher display resolutions.

Higher is better
Even so it has lower graphics clock rate, the NVIDIA Quadro FX 4500 X2 GPU comes with twice as many TMUs (Texture Mapping Units), which results in much better texture fill rate. Better maximum texture fill rate allows the graphics card to apply more textures and/or utilize more sophisticated 3D effects for each texel, which improves visual appearance of games and generated images.
