Radeon HD 5970 vs Radeon RX 560

Intro

The Radeon HD 5970 features a clock speed of 725 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 256-bit memory bus, and uses a 40 nm design. It is made up of 1600 SPUs, 160 Texture Address Units, and 64 Raster Operation Units.

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

Radeon RX 560 114688 MB/sec
Difference: 141312 (123%)

Texel Rate

The Radeon HD 5970 should be quite a bit (approximately 209%) better at anisotropic filtering than the Radeon RX 560. (explain)

Radeon HD 5970 232000 Mtexels/sec
Radeon RX 560 75200 Mtexels/sec
Difference: 156800 (209%)

Pixel Rate

The Radeon HD 5970 will be much (more or less 394%) more effective at FSAA than the Radeon RX 560, and also able to handle higher screen resolutions better. (explain)

Radeon HD 5970 92800 Mpixels/sec
Radeon RX 560 18800 Mpixels/sec
Difference: 74000 (394%)

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.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher 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 number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units by the core clock 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
