Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 250 should be 15% quicker than the Radeon R7 M260X in general, due to its higher bandwidth. (explain)

Radeon R7 250		73600 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 9600 (15%)

Texel Rate

The Radeon R7 250 should be quite a bit (about 21%) better at texture filtering than the Radeon R7 M260X. (explain)

Radeon R7 250		24000 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 4200 (21%)

Pixel Rate

The Radeon R7 250 will be much (approximately 21%) better at FSAA than the Radeon R7 M260X, and should be capable of handling higher screen resolutions while still performing well. (explain)

Radeon R7 250		8000 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 1400 (21%)

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 transported past the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher 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 number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
