Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Performance-wise, the GeForce GTX 560 should in theory be a bit superior to the GeForce GTX 460 (OEM) in general. (explain)

GeForce GTX 560		128128 MB/sec
GeForce GTX 460 (OEM)		108800 MB/sec
	Difference: 19328 (18%)

Texel Rate

The GeForce GTX 560 should be much (more or less 25%) more effective at AF than the GeForce GTX 460 (OEM). (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce GTX 460 (OEM)		36400 Mtexels/sec
	Difference: 8960 (25%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 560 is the winner, by a large margin. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce GTX 460 (OEM)		20800 Mpixels/sec
	Difference: 5120 (25%)

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 transported past the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
