GeForce 930M vs Radeon R9 M370X

Intro

Compare those specifications to the Radeon R9 M370X, which comes with a core clock speed of 800 MHz and a GDDR5 memory frequency of 1125 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M370X, in theory, should perform a lot faster than the GeForce 930M in general. (explain)

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

Texel Rate

The Radeon R9 M370X will be quite a bit (more or less 44%) faster with regards to anisotropic filtering than the GeForce 930M. (explain)

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

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M370X is a better choice, by far. (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: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If 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 texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units by the core clock 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 applied per second.

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