Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 390 8G should be 2300% faster than the Radeon R7 M260 in general, because of its greater bandwidth. (explain)

Radeon R9 390 8G		384000 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 368000 (2300%)

Texel Rate

The Radeon R9 390 8G should be quite a bit (more or less 832%) more effective at AF than the Radeon R7 M260. (explain)

Radeon R9 390 8G		160000 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 142840 (832%)

Pixel Rate

The Radeon R9 390 8G will be quite a bit (more or less 1019%) better at anti-aliasing than the Radeon R7 M260, and will be capable of handling higher resolutions more effectively. (explain)

Radeon R9 390 8G		64000 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 58280 (1019%)

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 (measured in MB per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can 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 card's clock speed. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
