Radeon R7 260X		115 Watts
GeForce GTX 465		200 Watts
	Difference: 85 Watts (74%)

Memory Bandwidth

In theory, the Radeon R7 260X should be 1% faster than the GeForce GTX 465 overall, due to its greater data rate. (explain)

Radeon R7 260X		104000 MB/sec
GeForce GTX 465		102592 MB/sec
	Difference: 1408 (1%)

Texel Rate

The Radeon R7 260X will be much (approximately 131%) better at texture filtering than the GeForce GTX 465. (explain)

Radeon R7 260X		61600 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 34892 (131%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 465 is a better choice, though only just barely. (explain)

GeForce GTX 465		19424 Mpixels/sec
Radeon R7 260X		17600 Mpixels/sec
	Difference: 1824 (10%)

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 max amount of information (counted in MB per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, 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 card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
