Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750 Ti		60 Watts
Radeon R7 250X 2GB		95 Watts
	Difference: 35 Watts (58%)

Memory Bandwidth

In theory, the GeForce GTX 750 Ti should be 20% quicker than the Radeon R7 250X 2GB overall, because of its higher data rate. (explain)

GeForce GTX 750 Ti		86400 MB/sec
Radeon R7 250X 2GB		72000 MB/sec
	Difference: 14400 (20%)

Texel Rate

The GeForce GTX 750 Ti will be a little bit (about 2%) more effective at texture filtering than the Radeon R7 250X 2GB. (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
Radeon R7 250X 2GB		40000 Mtexels/sec
	Difference: 800 (2%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 750 Ti is superior to the Radeon R7 250X 2GB, not by a very large margin though. (explain)

GeForce GTX 750 Ti		16320 Mpixels/sec
Radeon R7 250X 2GB		16000 Mpixels/sec
	Difference: 320 (2%)

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 (counted in megabytes per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once 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 amount of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, 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 most pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
