The GeForce GTX 650 is much (about 71%) better at texture filtering than the Radeon R7 M260X. (explain)

GeForce GTX 650 33856 Mtexels/sec
Radeon R7 M260X 19800 Mtexels/sec
Difference: 14056 (71%)

Pixel Rate

The GeForce GTX 650 should be quite a bit (approximately 156%) faster with regards to AA than the Radeon R7 M260X, and will be able to handle higher screen resolutions better. (explain)

GeForce GTX 650 16928 Mpixels/sec
Radeon R7 M260X 6600 Mpixels/sec
Difference: 10328 (156%)

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.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. 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 fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
