Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R7 M260X should perform quite a bit faster than the GeForce 930M overall. (explain)

Radeon R7 M260X		64000 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 49600 (344%)

Texel Rate

The GeForce 930M should be a bit (more or less 12%) faster with regards to AF than the Radeon R7 M260X. (explain)

GeForce 930M		22272 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 2472 (12%)

Pixel Rate

The GeForce 930M will be a bit (approximately 12%) more effective at FSAA than the Radeon R7 M260X, and also should be able to handle higher screen resolutions more effectively. (explain)

GeForce 930M		7424 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 824 (12%)

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
