GeForce GTX 285 2GB		51840 Mtexels/sec
GeForce GTX 560 Ti 448		40992 Mtexels/sec
	Difference: 10848 (26%)

Pixel Rate

The GeForce GTX 560 Ti 448 will be a lot (approximately 41%) better at anti-aliasing than the GeForce GTX 285 2GB, and also should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 560 Ti 448		29280 Mpixels/sec
GeForce GTX 285 2GB		20736 Mpixels/sec
	Difference: 8544 (41%)

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 (counted in MB per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
