Radeon HD 6750 1GB		64000 MB/sec
GeForce 9600 GSO 384MB		38400 MB/sec
	Difference: 25600 (67%)

Texel Rate

The GeForce 9600 GSO 384MB is a bit (more or less 1%) more effective at anisotropic filtering than the Radeon HD 6750 1GB. (explain)

GeForce 9600 GSO 384MB		26400 Mtexels/sec
Radeon HD 6750 1GB		26100 Mtexels/sec
	Difference: 300 (1%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon HD 6750 1GB is the winner, by far. (explain)

Radeon HD 6750 1GB		11600 Mpixels/sec
GeForce 9600 GSO 384MB		6600 Mpixels/sec
	Difference: 5000 (76%)

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 information (measured in MB per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the 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 are processed per second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
