Radeon R7 M260		16000 MB/sec
	Difference: 112000 (700%)

Texel Rate

The GeForce GTX 880M is quite a bit (more or less 612%) more effective at AF than the Radeon R7 M260. (explain)

GeForce GTX 880M		122112 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 104952 (612%)

Pixel Rate

The GeForce GTX 880M should be a lot (about 434%) faster with regards to anti-aliasing than the Radeon R7 M260, and also capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 880M		30528 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 24808 (434%)

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 maximum amount of information (measured in megabytes per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output 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 potential to reach the max fill rate.
