GeForce 930M vs Radeon R9 M375X

Intro

Compare all of that to the Radeon R9 M375X, which has GPU core speed of 1015 MHz, and 4096 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also is comprised of 640 Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M375X should be 400% quicker than the GeForce 930M overall, because of its greater bandwidth. (explain)

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

Texel Rate

The Radeon R9 M375X will be a lot (more or less 82%) more effective at texture 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 should be quite a bit (about 119%) faster with regards to AA than the GeForce 930M, and also will be 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 largest amount of information (in units of MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
