	Difference: 28800 (50%)

Texel Rate

The GeForce GTX 650 Ti 2GB should be much (approximately 186%) more effective at AF than the GeForce 9600 GT 1GB. (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
GeForce 9600 GT 1GB		20800 Mtexels/sec
	Difference: 38592 (186%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 650 Ti 2GB is the winner, by far. (explain)

GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
GeForce 9600 GT 1GB		10400 Mpixels/sec
	Difference: 4448 (43%)

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 maximum amount of information (measured in megabytes per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units 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 applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
