Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 260 Core 216 should be quite a bit faster than the Radeon R7 M265 in general. (explain)

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

Texel Rate

The GeForce GTX 260 Core 216 will be much (more or less 138%) better at texture filtering than the Radeon R7 M265. (explain)

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

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 260 Core 216 is a better choice, by far. (explain)

GeForce GTX 260 Core 216		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: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
