Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 880M will be 700% quicker than the Radeon R7 M260 in general, due to its greater bandwidth. (explain)

GeForce GTX 880M		128000 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 112000 (700%)

Texel Rate

The GeForce GTX 880M should be quite a bit (about 612%) better at anisotropic filtering 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 quite a bit (more or less 434%) more effective at anti-aliasing than the Radeon R7 M260, and will be capable of handling higher resolutions without losing too much performance. (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: Bandwidth is the maximum amount of data (measured in MB per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 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 anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the 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 maximum amount of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
