GeForce GTX 970M vs Radeon RX 560

Intro

Compare that to the Radeon RX 560, which uses a 14 nm design. AMD has clocked the core speed at 1175 MHz. The GDDR5 RAM works at a frequency of 1750 MHz on this specific card. It features 1024 SPUs as well as 64 Texture Address Units and 16 ROPs.

GeForce GTX 970M		96000 MB/sec
	Difference: 18688 (19%)

Texel Rate

The Radeon RX 560 will be a bit (about 2%) faster with regards to texture filtering than the GeForce GTX 970M. (explain)

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

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 970M is a better choice, by a large margin. (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: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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 memory bandwidth is, the lower the ability to reach the max fill rate.
