Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 260 216SP 55 nm, in theory, should perform a lot faster than the Radeon R7 M265 overall. (explain)

GeForce GTX 260 216SP 55 nm		111888 MB/sec
Radeon R7 M265		32000 MB/sec
	Difference: 79888 (250%)

Texel Rate

The GeForce GTX 260 216SP 55 nm is quite a bit (more or less 138%) more effective at anisotropic filtering than the Radeon R7 M265. (explain)

GeForce GTX 260 216SP 55 nm		41472 Mtexels/sec
Radeon R7 M265		17400 Mtexels/sec
	Difference: 24072 (138%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 260 216SP 55 nm is superior to the Radeon R7 M265, by far. (explain)

GeForce GTX 260 216SP 55 nm		16128 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 10328 (178%)

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 (counted in megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
