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

Texel Rate

The GeForce GTX 650 Ti 2GB will be quite a bit (approximately 48%) faster with regards to AF than the Radeon R7 250X 2GB. (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
Radeon R7 250X 2GB		40000 Mtexels/sec
	Difference: 19392 (48%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R7 250X 2GB is the winner, but it probably won't make a huge difference. (explain)

Radeon R7 250X 2GB		16000 Mpixels/sec
GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
	Difference: 1152 (8%)

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 maximum amount of data (in units of MB per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of 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 handling 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 can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
