Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 260X		115 Watts
GeForce GTX 260 216SP 55 nm		171 Watts
	Difference: 56 Watts (49%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 260 216SP 55 nm should be 8% faster than the Radeon R7 260X overall, because of its greater bandwidth. (explain)

GeForce GTX 260 216SP 55 nm		111888 MB/sec
Radeon R7 260X		104000 MB/sec
	Difference: 7888 (8%)

Texel Rate

The Radeon R7 260X is much (approximately 49%) faster with regards to AF than the GeForce GTX 260 216SP 55 nm. (explain)

Radeon R7 260X		61600 Mtexels/sec
GeForce GTX 260 216SP 55 nm		41472 Mtexels/sec
	Difference: 20128 (49%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R7 260X is superior to the GeForce GTX 260 216SP 55 nm, but only just. (explain)

Radeon R7 260X		17600 Mpixels/sec
GeForce GTX 260 216SP 55 nm		16128 Mpixels/sec
	Difference: 1472 (9%)

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 (counted in megabytes per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
