Radeon R7 250X 2GB		72000 MB/sec
	Difference: 14400 (20%)

Texel Rate

The Radeon R7 250X 2GB will be a small bit (about 6%) faster with regards to anisotropic filtering than the GeForce GTX 460. (explain)

Radeon R7 250X 2GB		40000 Mtexels/sec
GeForce GTX 460		37800 Mtexels/sec
	Difference: 2200 (6%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 460 is a better choice, not by a very large margin though. (explain)

GeForce GTX 460		16200 Mpixels/sec
Radeon R7 250X 2GB		16000 Mpixels/sec
	Difference: 200 (1%)

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 largest amount of data (in units of megabytes per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units of the card by the core clock 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record 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 core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
