Radeon R7 M265		32000 MB/sec
	Difference: 40000 (125%)

Texel Rate

The Radeon R7 250X is quite a bit (more or less 130%) more effective at AF than the Radeon R7 M265. (explain)

Radeon R7 250X		40000 Mtexels/sec
Radeon R7 M265		17400 Mtexels/sec
	Difference: 22600 (130%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R7 250X is superior to the Radeon R7 M265, and very much so. (explain)

Radeon R7 250X		16000 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 10200 (176%)

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 largest amount of data (counted in MB per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 processed in one second. This number is calculated 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
