GeForce GTX 650		80000 MB/sec
	Difference: 28800 (36%)

Texel Rate

The GeForce GTX 650 is a bit (approximately 9%) better at anisotropic filtering than the GeForce GTX 460 SE. (explain)

GeForce GTX 650		33856 Mtexels/sec
GeForce GTX 460 SE		31200 Mtexels/sec
	Difference: 2656 (9%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 460 SE is the winner, and very much so. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
GeForce GTX 650		16928 Mpixels/sec
	Difference: 3872 (23%)

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 moved across the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once 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 anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many 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.
