Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M295X is 1122% quicker than the GeForce 930M overall, because of its higher data rate. (explain)

Radeon R9 M295X		176000 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 161600 (1122%)

Texel Rate

The Radeon R9 M295X should be quite a bit (more or less 331%) faster with regards to AF than the GeForce 930M. (explain)

Radeon R9 M295X		96000 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 73728 (331%)

Pixel Rate

The Radeon R9 M295X is quite a bit (about 223%) faster with regards to anti-aliasing than the GeForce 930M, and also capable of handling higher resolutions without slowing down too much. (explain)

Radeon R9 M295X		24000 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 16576 (223%)

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 (counted in MB per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR memory, it must 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 anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

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