GeForce GTX 970M vs Radeon RX 560

Intro

Compare those specifications to the Radeon RX 560, which makes use of a 14 nm design. AMD has set the core frequency at 1175 MHz. The GDDR5 RAM works at a frequency of 1750 MHz on this particular model. It features 1024 SPUs along with 64 TAUs and 16 Rasterization Operator Units.

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

Performance-wise, the Radeon RX 560 should in theory be a little bit superior to the GeForce GTX 970M overall. (explain)

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

Texel Rate

The Radeon RX 560 is a small bit (approximately 2%) better at anisotropic filtering 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 will be quite a bit (approximately 136%) better at AA than the Radeon RX 560, and also 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 maximum amount of information (measured in megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant 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.
