GeForce GTX 960M		65 Watts
Radeon R7 250X 2GB		95 Watts
	Difference: 30 Watts (46%)

Memory Bandwidth

Theoretically speaking, the Radeon R7 250X 2GB should be 13% quicker than the GeForce GTX 960M in general, because of its higher bandwidth. (explain)

Radeon R7 250X 2GB		72000 MB/sec
GeForce GTX 960M		64000 MB/sec
	Difference: 8000 (13%)

Texel Rate

The GeForce GTX 960M will be a little bit (about 10%) faster with regards to texture filtering than the Radeon R7 250X 2GB. (explain)

GeForce GTX 960M		43840 Mtexels/sec
Radeon R7 250X 2GB		40000 Mtexels/sec
	Difference: 3840 (10%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 960M is superior to the Radeon R7 250X 2GB, though not by far. (explain)

GeForce GTX 960M		17536 Mpixels/sec
Radeon R7 250X 2GB		16000 Mpixels/sec
	Difference: 1536 (10%)

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 transported over the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the 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 amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated 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 output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
