GeForce 930M vs Radeon R9 M370X

Intro

Compare all of that to the Radeon R9 M370X, which comes with core clock speeds of 800 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 RAM. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R9 M370X should be a lot faster than the GeForce 930M overall. (explain)

Radeon R9 M370X		72000 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 57600 (400%)

Texel Rate

The Radeon R9 M370X is much (more or less 44%) better at AF than the GeForce 930M. (explain)

Radeon R9 M370X		32000 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 9728 (44%)

Pixel Rate

The Radeon R9 M370X will be quite a bit (about 72%) better at AA than the GeForce 930M, and will be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon R9 M370X		12800 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 5376 (72%)

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 data (in units of MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units of the card 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 applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock 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 fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
