Radeon R7 M260		16000 MB/sec
	Difference: 176384 (1102%)

Texel Rate

The GeForce GTX 580 is quite a bit (about 188%) faster with regards to texture filtering than the Radeon R7 M260. (explain)

GeForce GTX 580		49408 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 32248 (188%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 580 is superior to the Radeon R7 M260, by far. (explain)

GeForce GTX 580		37056 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 31336 (548%)

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 data (measured in MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR RAM, the result 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 anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one 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 clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
