Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R7 M260X is 18% quicker than the GeForce GT 340 1GB overall, due to its higher data rate. (explain)

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

Texel Rate

The Radeon R7 M260X should be just a bit (approximately 13%) more effective at 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 a lot (more or less 50%) more effective at anti-aliasing than the GeForce GT 340 1GB, and also will be capable of handling higher resolutions without slowing down too much. (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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (counted in megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units by the core 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 applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
