Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GTS (G92)		135 Watts
GeForce GTX 560 Ti		170 Watts
	Difference: 35 Watts (26%)

Memory Bandwidth

In theory, the GeForce GTX 560 Ti will be 107% faster than the GeForce 8800 GTS (G92) overall, due to its higher bandwidth. (explain)

GeForce GTX 560 Ti		128256 MB/sec
GeForce 8800 GTS (G92)		62080 MB/sec
	Difference: 66176 (107%)

Texel Rate

The GeForce GTX 560 Ti will be quite a bit (approximately 26%) faster with regards to AF than the GeForce 8800 GTS (G92). (explain)

GeForce GTX 560 Ti		52608 Mtexels/sec
GeForce 8800 GTS (G92)		41600 Mtexels/sec
	Difference: 11008 (26%)

Pixel Rate

The GeForce GTX 560 Ti should be a lot (more or less 153%) more effective at FSAA than the GeForce 8800 GTS (G92), and should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
GeForce 8800 GTS (G92)		10400 Mpixels/sec
	Difference: 15904 (153%)

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 largest amount of information (measured in MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
