GeForce GTX 970M vs Radeon RX 560

Intro

Compare those specifications 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 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 970M		75 Watts
Radeon RX 560		80 Watts
	Difference: 5 Watts (7%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 560 is 19% faster than the GeForce GTX 970M overall, due to its greater data rate. (explain)

Radeon RX 560		114688 MB/sec
GeForce GTX 970M		96000 MB/sec
	Difference: 18688 (19%)

Texel Rate

The Radeon RX 560 is a little bit (more or less 2%) more effective at AF than the GeForce GTX 970M. (explain)

Radeon RX 560		75200 Mtexels/sec
GeForce GTX 970M		73920 Mtexels/sec
	Difference: 1280 (2%)

Pixel Rate

The GeForce GTX 970M is quite a bit (more or less 136%) more effective at FSAA than the Radeon RX 560, and will be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 970M		44352 Mpixels/sec
Radeon RX 560		18800 Mpixels/sec
	Difference: 25552 (136%)

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 transported over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can 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 Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
