Texel Rate

The GeForce GTX 460 1GB should be quite a bit (approximately 21%) better at texture filtering than the GeForce GTX 460 SE. (explain)

GeForce GTX 460 1GB		37800 Mtexels/sec
GeForce GTX 460 SE		31200 Mtexels/sec
	Difference: 6600 (21%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 460 1GB is the winner, but only just. (explain)

GeForce GTX 460 1GB		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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
