GeForce 9600 GT 1GB		95 Watts
	Difference: 9 Watts (10%)

Memory Bandwidth

The Radeon HD 6750 1GB, in theory, should perform just a bit faster than the GeForce 9600 GT 1GB in general. (explain)

Radeon HD 6750 1GB		64000 MB/sec
GeForce 9600 GT 1GB		57600 MB/sec
	Difference: 6400 (11%)

Texel Rate

The Radeon HD 6750 1GB should be much (about 25%) more effective at anisotropic filtering than the GeForce 9600 GT 1GB. (explain)

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

Pixel Rate

If running with high levels of AA is important to you, then the Radeon HD 6750 1GB is a better choice, though not by far. (explain)

Radeon HD 6750 1GB		11600 Mpixels/sec
GeForce 9600 GT 1GB		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: Bandwidth is the max amount of data (measured in MB per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units of the card 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 a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
