Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M375 should be 144% quicker than the GeForce 930M overall, because of its greater data rate. (explain)

Radeon R9 M375		35200 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 20800 (144%)

Texel Rate

The Radeon R9 M375 is quite a bit (approximately 82%) more effective at texture filtering than the GeForce 930M. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 18328 (82%)

Pixel Rate

The Radeon R9 M375 should be a lot (about 119%) better at full screen anti-aliasing than the GeForce 930M, and also should be able to handle higher screen resolutions more effectively. (explain)

Radeon R9 M375		16240 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 8816 (119%)

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 information (counted in MB per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out 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 outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
