Radeon R7 250X 2GB		72000 MB/sec
GeForce 8800 GTS (G92)		62080 MB/sec
	Difference: 9920 (16%)

Texel Rate

The GeForce 8800 GTS (G92) will be a little bit (approximately 4%) faster with regards to anisotropic filtering than the Radeon R7 250X 2GB. (explain)

GeForce 8800 GTS (G92)		41600 Mtexels/sec
Radeon R7 250X 2GB		40000 Mtexels/sec
	Difference: 1600 (4%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R7 250X 2GB is a better choice, and very much so. (explain)

Radeon R7 250X 2GB		16000 Mpixels/sec
GeForce 8800 GTS (G92)		10400 Mpixels/sec
	Difference: 5600 (54%)

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 max amount of data (measured in MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the 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 maximum amount of pixels that the graphics card can possibly record to its 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 - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
