GeForce GTX 590 vs Radeon RX 560

Intro

Compare all of that to the Radeon RX 560, which has a core clock speed of 1175 MHz and a GDDR5 memory speed of 1750 MHz. It also makes use of a 128-bit bus, and makes use of a 14 nm design. It features 1024 SPUs, 64 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 560		80 Watts
GeForce GTX 590		365 Watts
	Difference: 285 Watts (356%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 590 should be 186% quicker than the Radeon RX 560 in general, due to its higher data rate. (explain)

GeForce GTX 590		328320 MB/sec
Radeon RX 560		114688 MB/sec
	Difference: 213632 (186%)

Texel Rate

The GeForce GTX 590 is just a bit (more or less 3%) faster with regards to anisotropic filtering than the Radeon RX 560. (explain)

GeForce GTX 590		77696 Mtexels/sec
Radeon RX 560		75200 Mtexels/sec
	Difference: 2496 (3%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 590 is superior to the Radeon RX 560, by far. (explain)

GeForce GTX 590		58272 Mpixels/sec
Radeon RX 560		18800 Mpixels/sec
	Difference: 39472 (210%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour 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 rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
