Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GT 340 is 70% quicker than the Radeon R7 M265 in general, because of its higher bandwidth. (explain)

GeForce GT 340		54400 MB/sec
Radeon R7 M265		32000 MB/sec
	Difference: 22400 (70%)

Texel Rate

The GeForce GT 340 will be a small bit (more or less 1%) more effective at AF than the Radeon R7 M265. (explain)

GeForce GT 340		17600 Mtexels/sec
Radeon R7 M265		17400 Mtexels/sec
	Difference: 200 (1%)

Pixel Rate

The Radeon R7 M265 will be quite a bit (about 32%) more effective at FSAA than the GeForce GT 340, and also able to handle higher screen resolutions while still performing well. (explain)

Radeon R7 M265		5800 Mpixels/sec
GeForce GT 340		4400 Mpixels/sec
	Difference: 1400 (32%)

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 maximum amount of information (in units of megabytes per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, 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 figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics 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 number of Raster Operations Pipelines by the clock speed of the card. 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 lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
