Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 M260X should be a little bit faster than the GeForce GT 340 1GB overall. (explain)

Radeon R7 M260X		64000 MB/sec
GeForce GT 340 1GB		54400 MB/sec
	Difference: 9600 (18%)

Texel Rate

The Radeon R7 M260X will be a bit (about 13%) faster with regards to anisotropic filtering than the GeForce GT 340 1GB. (explain)

Radeon R7 M260X		19800 Mtexels/sec
GeForce GT 340 1GB		17600 Mtexels/sec
	Difference: 2200 (13%)

Pixel Rate

The Radeon R7 M260X is quite a bit (more or less 50%) more effective at anti-aliasing than the GeForce GT 340 1GB, and should be able to handle higher screen resolutions better. (explain)

Radeon R7 M260X		6600 Mpixels/sec
GeForce GT 340 1GB		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: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the 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 the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
