Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 3470 256MB is 90% quicker than the Radeon R7 M260 in general, due to its greater data rate. (explain)

Radeon HD 3470 256MB		30400 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 14400 (90%)

Texel Rate

The Radeon R7 M260 should be a lot (about 436%) better at AF than the Radeon HD 3470 256MB. (explain)

Radeon R7 M260		17160 Mtexels/sec
Radeon HD 3470 256MB		3200 Mtexels/sec
	Difference: 13960 (436%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R7 M260 is the winner, by a large margin. (explain)

Radeon R7 M260		5720 Mpixels/sec
Radeon HD 3470 256MB		3200 Mpixels/sec
	Difference: 2520 (79%)

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 data (counted in megabytes per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If it uses 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 high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units by the core 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 per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. 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 lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
