Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R5 M230 should be 11% faster than the GeForce 930M in general, because of its higher bandwidth. (explain)

Radeon R5 M230		16000 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 1600 (11%)

Texel Rate

The GeForce 930M is quite a bit (about 43%) better at texture filtering than the Radeon R5 M230. (explain)

GeForce 930M		22272 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 6672 (43%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce 930M is the winner, by a large margin. (explain)

GeForce 930M		7424 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 4304 (138%)

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 data (measured in MB per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's 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 are processed per second. This is calculated by multiplying the total amount of texture units of the card by the core 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
