Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 6750 1GB		86 Watts
GeForce 9600 GSO 512MB		90 Watts
	Difference: 4 Watts (5%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 6750 1GB is 11% quicker than the GeForce 9600 GSO 512MB overall, due to its greater data rate. (explain)

Radeon HD 6750 1GB		64000 MB/sec
GeForce 9600 GSO 512MB		57600 MB/sec
	Difference: 6400 (11%)

Texel Rate

The GeForce 9600 GSO 512MB is a little bit (more or less 20%) more effective at anisotropic filtering than the Radeon HD 6750 1GB. (explain)

GeForce 9600 GSO 512MB		31200 Mtexels/sec
Radeon HD 6750 1GB		26100 Mtexels/sec
	Difference: 5100 (20%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 6750 1GB is a better choice, though only just barely. (explain)

Radeon HD 6750 1GB		11600 Mpixels/sec
GeForce 9600 GSO 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: Bandwidth is the maximum amount of data (counted in MB per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels 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 a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines 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 many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
