GeForce GTX 650		80000 MB/sec
	Difference: 32000 (40%)

Texel Rate

The Radeon RX 460 2GB should be much (about 80%) better at AF than the GeForce GTX 650. (explain)

Radeon RX 460 2GB		61040 Mtexels/sec
GeForce GTX 650		33856 Mtexels/sec
	Difference: 27184 (80%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 460 2GB is a better choice, though only just barely. (explain)

Radeon RX 460 2GB		17440 Mpixels/sec
GeForce GTX 650		16928 Mpixels/sec
	Difference: 512 (3%)

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: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
