The Radeon R7 250X should in theory perform just a bit faster than the GeForce 8800 GTS (G92) in general. (explain)

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

Texel Rate

The GeForce 8800 GTS (G92) should be a bit (approximately 4%) better at texture 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 is quite a bit (approximately 54%) faster with regards to full screen anti-aliasing than the GeForce 8800 GTS (G92), and should be able to handle higher resolutions while still performing well. (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: Bandwidth is the max amount of information (counted in megabytes per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount 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 better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
