Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 290X should perform quite a bit faster than the Radeon R7 M260X overall. (explain)

Radeon R9 290X		320000 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 256000 (400%)

Texel Rate

The Radeon R9 290X should be a lot (approximately 611%) faster with regards to anisotropic filtering than the Radeon R7 M260X. (explain)

Radeon R9 290X		140800 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 121000 (611%)

Pixel Rate

The Radeon R9 290X will be quite a bit (more or less 676%) faster with regards to FSAA than the Radeon R7 M260X, and should be capable of handling higher screen resolutions more effectively. (explain)

Radeon R9 290X		51200 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 44600 (676%)

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 (counted in MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video 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 number of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. 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 quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
