GeForce GTX 880M vs Radeon RX 560

Intro

The GeForce GTX 880M makes use of a 28 nm design. nVidia has set the core speed at 954 MHz. The GDDR5 RAM is set to run at a frequency of 1000 MHz on this specific card. It features 1536 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.

Compare all of that to the Radeon RX 560, which comes with a core clock frequency of 1175 MHz and a GDDR5 memory speed of 7000 MHz. It also features a 128-bit memory bus, and makes use of a 14 nm design. It is comprised of 1024 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 560 80 Watts
GeForce GTX 880M 130 Watts
Difference: 50 Watts (63%)

Memory Bandwidth

The GeForce GTX 880M should in theory be a little bit faster than the Radeon RX 560 in general. (explain)

GeForce GTX 880M 128000 MB/sec
Radeon RX 560 114688 MB/sec
Difference: 13312 (12%)

Texel Rate

The GeForce GTX 880M should be quite a bit (approximately 62%) better at texture filtering than the Radeon RX 560. (explain)

GeForce GTX 880M 122112 Mtexels/sec
Radeon RX 560 75200 Mtexels/sec
Difference: 46912 (62%)

Pixel Rate

The GeForce GTX 880M should be much (more or less 62%) more effective at anti-aliasing than the Radeon RX 560, and will be able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 880M 30528 Mpixels/sec
Radeon RX 560 18800 Mpixels/sec
Difference: 11728 (62%)

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: Bandwidth is the max amount of data (measured in megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number 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 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 most pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
