Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R7 M260X will be 122% quicker than the Radeon HD 5570 overall, due to its greater bandwidth. (explain)

Radeon R7 M260X		64000 MB/sec
Radeon HD 5570		28800 MB/sec
	Difference: 35200 (122%)

Texel Rate

The Radeon R7 M260X should be a lot (more or less 52%) more effective at texture filtering than the Radeon HD 5570. (explain)

Radeon R7 M260X		19800 Mtexels/sec
Radeon HD 5570		13000 Mtexels/sec
	Difference: 6800 (52%)

Pixel Rate

The Radeon R7 M260X is quite a bit (more or less 27%) more effective at FSAA than the Radeon HD 5570, and also able to handle higher screen resolutions without losing too much performance. (explain)

Radeon R7 M260X		6600 Mpixels/sec
Radeon HD 5570		5200 Mpixels/sec
	Difference: 1400 (27%)

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 data (measured in megabytes per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

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