GeForce 9600 GT 1GB		57600 MB/sec
	Difference: 230784 (401%)

Texel Rate

The Geforce GTX 780 is quite a bit (approximately 697%) better at anisotropic filtering than the GeForce 9600 GT 1GB. (explain)

Geforce GTX 780		165696 Mtexels/sec
GeForce 9600 GT 1GB		20800 Mtexels/sec
	Difference: 144896 (697%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Geforce GTX 780 is a better choice, by a large margin. (explain)

Geforce GTX 780		41424 Mpixels/sec
GeForce 9600 GT 1GB		10400 Mpixels/sec
	Difference: 31024 (298%)

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 (measured in megabytes per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to 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 get to the max fill rate.
