Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 250X		95 Watts
GeForce 8800 GTS (G92)		135 Watts
	Difference: 40 Watts (42%)

Memory Bandwidth

Theoretically speaking, the Radeon R7 250X will be 16% quicker than the GeForce 8800 GTS (G92) overall, due to its higher bandwidth. (explain)

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

Texel Rate

The GeForce 8800 GTS (G92) will be just a bit (approximately 4%) more effective at anisotropic filtering than the Radeon R7 250X. (explain)

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

Pixel Rate

The Radeon R7 250X should be quite a bit (more or less 54%) faster with regards to AA than the GeForce 8800 GTS (G92), and will be capable of handling higher resolutions more effectively. (explain)

Radeon R7 250X		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 largest amount of data (counted in MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better 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 that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
