GeForce GTX 860M vs Radeon RX 560

Intro

Compare those specifications to the Radeon RX 560, which features a GPU core clock speed of 1175 MHz, and 4096 MB of GDDR5 memory running at 1750 MHz through a 128-bit bus. It also is made up of 1024 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 860M		45 Watts
Radeon RX 560		80 Watts
	Difference: 35 Watts (78%)

Memory Bandwidth

The Radeon RX 560 should in theory be much faster than the GeForce GTX 860M in general. (explain)

Radeon RX 560		114688 MB/sec
GeForce GTX 860M		64000 MB/sec
	Difference: 50688 (79%)

Texel Rate

The GeForce GTX 860M is a bit (approximately 2%) more effective at texture filtering than the Radeon RX 560. (explain)

GeForce GTX 860M		76512 Mtexels/sec
Radeon RX 560		75200 Mtexels/sec
	Difference: 1312 (2%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 560 is the winner, and very much so. (explain)

Radeon RX 560		18800 Mpixels/sec
GeForce GTX 860M		12752 Mpixels/sec
	Difference: 6048 (47%)

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 data (measured in megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
