Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 M260 is 11% quicker than the GeForce 825M in general, due to its higher bandwidth. (explain)

Radeon R7 M260		16000 MB/sec
GeForce 825M		14400 MB/sec
	Difference: 1600 (11%)

Texel Rate

The Radeon R7 M260 should be quite a bit (more or less 26%) faster with regards to AF than the GeForce 825M. (explain)

Radeon R7 M260		17160 Mtexels/sec
GeForce 825M		13600 Mtexels/sec
	Difference: 3560 (26%)

Pixel Rate

The GeForce 825M is a bit (more or less 19%) faster with regards to AA than the Radeon R7 M260, and also able to handle higher screen resolutions better. (explain)

GeForce 825M		6800 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 1080 (19%)

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 across the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once 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 anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total texture units of the card by the core 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount 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 output 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 ability to reach the max fill rate.
