GeForce 930M vs Radeon R9 M375X

Intro

Compare those specifications to the Radeon R9 M375X, which makes use of a 28 nm design. AMD has set the core speed at 1015 MHz. The GDDR5 memory is set to run at a speed of 1125 MHz on this particular model. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M375X should theoretically be a lot faster than the GeForce 930M overall. (explain)

Radeon R9 M375X		72000 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 57600 (400%)

Texel Rate

The Radeon R9 M375X will be quite a bit (more or less 82%) better at anisotropic filtering than the GeForce 930M. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 18328 (82%)

Pixel Rate

The Radeon R9 M375X will be a lot (about 119%) better at full screen anti-aliasing than the GeForce 930M, and able to handle higher resolutions without slowing down too much. (explain)

Radeon R9 M375X		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: Bandwidth is the max amount of information (in units of megabytes per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the 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 most pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
