Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M375X should be 400% quicker than the GeForce 830M overall, due to its higher data rate. (explain)

Radeon R9 M375X		72000 MB/sec
GeForce 830M		14400 MB/sec
	Difference: 57600 (400%)

Texel Rate

The Radeon R9 M375X will be a lot (approximately 147%) faster with regards to AF than the GeForce 830M. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce 830M		16464 Mtexels/sec
	Difference: 24136 (147%)

Pixel Rate

The Radeon R9 M375X is much (approximately 97%) more effective at AA than the GeForce 830M, and will be able to handle higher screen resolutions more effectively. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce 830M		8232 Mpixels/sec
	Difference: 8008 (97%)

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 max amount of data (measured in megabytes per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can 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 Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
