Leadtek WinFast A6600 LE 128MB vs NVIDIA GeForce 6600 GT

Theoretical performance comparison

Each card has several important theoretical parameters that influence real-world game, 3D graphics and compute performance. They are pixel fillrate, texture fillrate, memory bandwidth, single-precision performance and double-precision performance. Below we explain why these characteristics are essential and which card has better specs.

Pixel fill rate (gigapixels/s)

2.4

1.8

1.2

0.6

1.2

Higher is better

Since both graphics units have the same number of ROPs, and the GeForce 6600 GT is clocked significantly higher, it also has higher pixel fillrate. Better pixel fill rate allows more pixels to be drawn on screen per second, and is an indication of better GPU performance, unless there are bottlenecks in other areas, such as texture mapping or memory bandwidth.

Texture fill rate (gigatexels/s)

1.2

Higher is better

Because the NVIDIA GeForce 6600 GT has twice as many TMUs and substantially higher graphics clock, its texture fillrate is considerably higher. Having better maximum texture fill rate allows the card to use more sophisticated 3D effects and/or apply more textures to each texel, which improves visual appearance of games and generated images.

Vertex Fill rate (gigavertices/s)

0.5

0.4

0.3

0.2

0.1

0.23

0.38

Higher is better

Memory bandwidth (GB/s)

8.8

Higher is better

To speed up processing, the graphics cards store 3D scene data, textures and intermediate data, used for image generation, in on-board memory. The video memory usually has much higher bandwidth than system RAM, and more bandwidth allows the GPU to run at higher display resolutions, use larger and more detailed textures, and apply more complex 3D effects and filters. Memory type, speed, and memory interface width all affect the bandwidth value. Specifically, higher memory bandwidth of the NVIDIA GeForce 6600 GT is due to better and higher clocked memory.
