GeForce GTX 560 Ti		128256 MB/sec
Radeon R9 M385X		96000 MB/sec
	Difference: 32256 (34%)

Texel Rate

The Radeon R9 M385X will be a bit (approximately 17%) faster with regards to AF than the GeForce GTX 560 Ti. (explain)

Radeon R9 M385X		61600 Mtexels/sec
GeForce GTX 560 Ti		52608 Mtexels/sec
	Difference: 8992 (17%)

Pixel Rate

The GeForce GTX 560 Ti is a lot (about 49%) better at anti-aliasing than the Radeon R9 M385X, and should be able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
Radeon R9 M385X		17600 Mpixels/sec
	Difference: 8704 (49%)

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 data (in units of megabytes per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once 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 AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core 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 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 maximum fill rate.
