Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R7 250, in theory, should perform a little bit faster than the Radeon R9 M370X overall. (explain)

Radeon R7 250		73600 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 1600 (2%)

Texel Rate

The Radeon R9 M370X should be much (more or less 33%) more effective at anisotropic filtering than the Radeon R7 250. (explain)

Radeon R9 M370X		32000 Mtexels/sec
Radeon R7 250		24000 Mtexels/sec
	Difference: 8000 (33%)

Pixel Rate

The Radeon R9 M370X is quite a bit (more or less 60%) more effective at FSAA than the Radeon R7 250, and capable of handling higher resolutions more effectively. (explain)

Radeon R9 M370X		12800 Mpixels/sec
Radeon R7 250		8000 Mpixels/sec
	Difference: 4800 (60%)

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 maximum amount of data (measured in megabytes per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR type 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 AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at 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 the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. 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 output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
