Radeon R7 250		73600 MB/sec
GeForce 9600 GSO 768MB		38400 MB/sec
	Difference: 35200 (92%)

Texel Rate

The GeForce 9600 GSO 768MB should be a small bit (approximately 10%) better at AF than the Radeon R7 250. (explain)

GeForce 9600 GSO 768MB		26400 Mtexels/sec
Radeon R7 250		24000 Mtexels/sec
	Difference: 2400 (10%)

Pixel Rate

The Radeon R7 250 should be a lot (approximately 21%) better at anti-aliasing than the GeForce 9600 GSO 768MB, and also will be capable of handling higher resolutions without slowing down too much. (explain)

Radeon R7 250		8000 Mpixels/sec
GeForce 9600 GSO 768MB		6600 Mpixels/sec
	Difference: 1400 (21%)

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 maximum amount of data (in units of megabytes per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher 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 a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
