GeForce 940M vs Radeon RX 560

Intro

Compare all of that to the Radeon RX 560, which has GPU clock speed of 1175 MHz, and 4096 MB of GDDR5 memory set to run at 1750 MHz through a 128-bit bus. It also is made up of 1024 Stream Processors, 64 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon RX 560 will be 617% quicker than the GeForce 940M overall, due to its higher data rate. (explain)

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

Texel Rate

The Radeon RX 560 should be quite a bit (approximately 192%) better at texture 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 will be quite a bit (about 119%) better at full screen anti-aliasing than the GeForce 940M, and should be able to handle 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 information (in units of MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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