The GeForce GTX 560 Ti 448 should be a bit (about 11%) better at texture filtering than the GeForce GTX 260. (explain)

GeForce GTX 560 Ti 448		40992 Mtexels/sec
GeForce GTX 260		36864 Mtexels/sec
	Difference: 4128 (11%)

Pixel Rate

The GeForce GTX 560 Ti 448 is a lot (more or less 82%) more effective at FSAA than the GeForce GTX 260, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 560 Ti 448		29280 Mpixels/sec
GeForce GTX 260		16128 Mpixels/sec
	Difference: 13152 (82%)

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 (counted in MB per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
