Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 465 is 60% faster than the Radeon R7 M260X in general, due to its greater bandwidth. (explain)

GeForce GTX 465		102592 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 38592 (60%)

Texel Rate

The GeForce GTX 465 should be much (about 35%) faster with regards to anisotropic filtering than the Radeon R7 M260X. (explain)

GeForce GTX 465		26708 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 6908 (35%)

Pixel Rate

The GeForce GTX 465 will be quite a bit (more or less 194%) faster with regards to full screen anti-aliasing than the Radeon R7 M260X, and will be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 465		19424 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 12824 (194%)

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 data (measured in MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
