GeForce GTX 980M vs Radeon RX 560

Intro

The GeForce GTX 980M comes with a core clock speed of 1038 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 256-bit bus, and uses a 28 nm design. It is made up of 1536 SPUs, 96 Texture Address Units, and 64 ROPs.

Compare that to the Radeon RX 560, which makes use of a 14 nm design. AMD has clocked the core speed at 1175 MHz. The GDDR5 memory works at a frequency of 7000 MHz on this particular model. It features 1024 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 560 80 Watts
GeForce GTX 980M 100 Watts
Difference: 20 Watts (25%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 980M should perform a little bit faster than the Radeon RX 560 in general. (explain)

GeForce GTX 980M 128000 MB/sec
Radeon RX 560 114688 MB/sec
Difference: 13312 (12%)

Texel Rate

The GeForce GTX 980M will be much (about 33%) faster with regards to AF than the Radeon RX 560. (explain)

GeForce GTX 980M 99648 Mtexels/sec
Radeon RX 560 75200 Mtexels/sec
Difference: 24448 (33%)

Pixel Rate

The GeForce GTX 980M should be a lot (more or less 253%) more effective at AA than the Radeon RX 560, and also should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 980M 66432 Mpixels/sec
Radeon RX 560 18800 Mpixels/sec
Difference: 47632 (253%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in MB per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

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