GeForce 940M vs Radeon RX 560

Intro

Compare all that to the Radeon RX 560, which features clock speeds of 1175 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 RAM. It features 1024 SPUs as well as 64 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon RX 560 should be quite a bit faster than the GeForce 940M overall. (explain)

Radeon RX 560		114688 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 98688 (617%)

Texel Rate

The Radeon RX 560 will be a lot (about 192%) better at anisotropic filtering than the GeForce 940M. (explain)

Radeon RX 560		75200 Mtexels/sec
GeForce 940M		25728 Mtexels/sec
	Difference: 49472 (192%)

Pixel Rate

The Radeon RX 560 is a lot (about 119%) more effective at FSAA than the GeForce 940M, and should be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon RX 560		18800 Mpixels/sec
GeForce 940M		8576 Mpixels/sec
	Difference: 10224 (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 data (in units of MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
