Radeon R7 M260		16000 MB/sec
	Difference: 95888 (599%)

Texel Rate

The GeForce GTX 260 Core 216 will be quite a bit (more or less 142%) more effective at AF than the Radeon R7 M260. (explain)

GeForce GTX 260 Core 216		41472 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 24312 (142%)

Pixel Rate

The GeForce GTX 260 Core 216 is quite a bit (about 182%) better at AA than the Radeon R7 M260, and also will be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 260 Core 216		16128 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 10408 (182%)

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 maximum amount of information (in units of MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 can be processed in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). 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 reach the max fill rate.
