Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R7 250X is 125% quicker than the Radeon R7 M265 in general, because of its higher bandwidth. (explain)

Radeon R7 250X		72000 MB/sec
Radeon R7 M265		32000 MB/sec
	Difference: 40000 (125%)

Texel Rate

The Radeon R7 250X should be much (more or less 130%) more effective at texture filtering than the Radeon R7 M265. (explain)

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

Pixel Rate

The Radeon R7 250X should be a lot (about 176%) faster with regards to AA than the Radeon R7 M265, and capable of handling higher resolutions without slowing down too much. (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: Memory bandwidth is the largest amount of information (counted in MB per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
