Radeon HD 5830		175 Watts
GeForce GTX 560 Ti 448		210 Watts
	Difference: 35 Watts (20%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 560 Ti 448 is 13% quicker than the Radeon HD 5830 overall, because of its greater bandwidth. (explain)

GeForce GTX 560 Ti 448		144000 MB/sec
Radeon HD 5830		128000 MB/sec
	Difference: 16000 (13%)

Texel Rate

The Radeon HD 5830 should be a little bit (about 9%) more effective at AF than the GeForce GTX 560 Ti 448. (explain)

Radeon HD 5830		44800 Mtexels/sec
GeForce GTX 560 Ti 448		40992 Mtexels/sec
	Difference: 3808 (9%)

Pixel Rate

The GeForce GTX 560 Ti 448 should be much (more or less 129%) faster with regards to AA than the Radeon HD 5830, and also will be capable of handling higher resolutions while still performing well. (explain)

GeForce GTX 560 Ti 448		29280 Mpixels/sec
Radeon HD 5830		12800 Mpixels/sec
	Difference: 16480 (129%)

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 max amount of data (counted in MB per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If 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, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the 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 maximum number of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
