Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R7 M260X, in theory, should perform just a bit faster than the GeForce GT 340 1GB in general. (explain)

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

Texel Rate

The Radeon R7 M260X is a small bit (more or less 13%) faster with regards to AF 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

If running with a high resolution is important to you, then the Radeon R7 M260X is the winner, by far. (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: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses 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, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
