Radeon HD 6770		67200 MB/sec
GeForce 9600 GSO 384MB		38400 MB/sec
	Difference: 28800 (75%)

Texel Rate

The Radeon HD 6770 will be quite a bit (more or less 36%) more effective at texture filtering than the GeForce 9600 GSO 384MB. (explain)

Radeon HD 6770		36000 Mtexels/sec
GeForce 9600 GSO 384MB		26400 Mtexels/sec
	Difference: 9600 (36%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon HD 6770 is superior to the GeForce 9600 GSO 384MB, by far. (explain)

Radeon HD 6770		14400 Mpixels/sec
GeForce 9600 GSO 384MB		6600 Mpixels/sec
	Difference: 7800 (118%)

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 largest amount of data (counted in megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
