Memory Bandwidth

The GeForce GTX 570, in theory, should perform a small bit faster than the GeForce GTX 560 Ti 448 in general. (explain)

GeForce GTX 570		152000 MB/sec
GeForce GTX 560 Ti 448		144000 MB/sec
	Difference: 8000 (6%)

Texel Rate

The GeForce GTX 570 should be just a bit (more or less 7%) more effective at anisotropic filtering than the GeForce GTX 560 Ti 448. (explain)

GeForce GTX 570		43920 Mtexels/sec
GeForce GTX 560 Ti 448		40992 Mtexels/sec
	Difference: 2928 (7%)

Pixel Rate

Both cards have the exact same pixel fill rate, so in theory they should perform equally good at at AA, and be capable of handling the same screen resolutions. (explain)

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 (in units of MB per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip 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 ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
