GeForce GTX 460 SE 108800 MB/sec
Difference: 6400 (6%)

Texel Rate

The GeForce GTX 460 2GB should be quite a bit (more or less 21%) better at AF than the GeForce GTX 460 SE. (explain)

GeForce GTX 460 2GB 37800 Mtexels/sec
GeForce GTX 460 SE 31200 Mtexels/sec
Difference: 6600 (21%)

Pixel Rate

The GeForce GTX 460 2GB is a bit (approximately 4%) better at anti-aliasing than the GeForce GTX 460 SE, and also will be capable of handling higher resolutions more effectively. (explain)

GeForce GTX 460 2GB 21600 Mpixels/sec
GeForce GTX 460 SE 20800 Mpixels/sec
Difference: 800 (4%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
