Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R7 M260X should theoretically be a small bit better than the GeForce GT 340 in general. (explain)

Radeon R7 M260X		64000 MB/sec
GeForce GT 340		54400 MB/sec
	Difference: 9600 (18%)

Texel Rate

The Radeon R7 M260X should be just a bit (about 13%) faster with regards to texture filtering than the GeForce GT 340. (explain)

Radeon R7 M260X		19800 Mtexels/sec
GeForce GT 340		17600 Mtexels/sec
	Difference: 2200 (13%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R7 M260X is the winner, by far. (explain)

Radeon R7 M260X		6600 Mpixels/sec
GeForce GT 340		4400 Mpixels/sec
	Difference: 2200 (50%)

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 (in units of megabytes per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock 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 amount of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
