	Difference: 6400 (11%)

Texel Rate

The Radeon HD 6750 1GB is a lot (more or less 25%) faster with regards to AF than the GeForce 9600 GT 512MB. (explain)

Radeon HD 6750 1GB		26100 Mtexels/sec
GeForce 9600 GT 512MB		20800 Mtexels/sec
	Difference: 5300 (25%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon HD 6750 1GB is a better choice, but only just. (explain)

Radeon HD 6750 1GB		11600 Mpixels/sec
GeForce 9600 GT 512MB		10400 Mpixels/sec
	Difference: 1200 (12%)

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 largest amount of data (in units of MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. 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 texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The better 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 its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
