Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 295X2 is 900% quicker than the Radeon R7 M260X overall, because of its higher bandwidth. (explain)

Radeon R9 295X2		640000 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 576000 (900%)

Texel Rate

The Radeon R9 295X2 is a lot (about 1710%) more effective at texture filtering than the Radeon R7 M260X. (explain)

Radeon R9 295X2		358336 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 338536 (1710%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 295X2 is the winner, and very much so. (explain)

Radeon R9 295X2		130304 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 123704 (1874%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units 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 of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
