The GeForce GTX 560 Ti is quite a bit (more or less 22%) better at texture filtering than the GeForce 9800 GTX. (explain)

GeForce GTX 560 Ti		52608 Mtexels/sec
GeForce 9800 GTX		43200 Mtexels/sec
	Difference: 9408 (22%)

Pixel Rate

The GeForce GTX 560 Ti is a lot (approximately 144%) faster with regards to AA than the GeForce 9800 GTX, and also will be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
GeForce 9800 GTX		10800 Mpixels/sec
	Difference: 15504 (144%)

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 max amount of information (in units of megabytes per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, 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 maximum amount of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
