Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650 Ti 2GB		110 Watts
Radeon R7 260X		115 Watts
	Difference: 5 Watts (5%)

Memory Bandwidth

Theoretically speaking, the Radeon R7 260X should be 20% faster than the GeForce GTX 650 Ti 2GB in general, because of its higher bandwidth. (explain)

Radeon R7 260X		104000 MB/sec
GeForce GTX 650 Ti 2GB		86400 MB/sec
	Difference: 17600 (20%)

Texel Rate

The Radeon R7 260X is a bit (more or less 4%) better at texture filtering than the GeForce GTX 650 Ti 2GB. (explain)

Radeon R7 260X		61600 Mtexels/sec
GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
	Difference: 2208 (4%)

Pixel Rate

The Radeon R7 260X is just a bit (about 19%) faster with regards to full screen anti-aliasing than the GeForce GTX 650 Ti 2GB, and will be capable of handling higher screen resolutions more effectively. (explain)

Radeon R7 260X		17600 Mpixels/sec
GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
	Difference: 2752 (19%)

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 (in units of megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's 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 is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
