Radeon HD 6870 vs Radeon RX 560

Intro

The Radeon HD 6870 has a GPU core clock speed of 900 MHz, and the 1024 MB of GDDR5 memory is set to run at 1050 MHz through a 256-bit bus. It also is made up of 1120 SPUs, 56 TAUs, and 32 Raster Operation Units.

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

Radeon RX 560 80 Watts
Radeon HD 6870 151 Watts
Difference: 71 Watts (89%)

Memory Bandwidth

Performance-wise, the Radeon HD 6870 should in theory be a little bit better than the Radeon RX 560 in general. (explain)

Radeon HD 6870 134400 MB/sec
Radeon RX 560 114688 MB/sec
Difference: 19712 (17%)

Texel Rate

The Radeon RX 560 should be quite a bit (approximately 49%) better at texture filtering than the Radeon HD 6870. (explain)

Radeon RX 560 75200 Mtexels/sec
Radeon HD 6870 50400 Mtexels/sec
Difference: 24800 (49%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 6870 is a better choice, by far. (explain)

Radeon HD 6870 28800 Mpixels/sec
Radeon RX 560 18800 Mpixels/sec
Difference: 10000 (53%)

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 megabytes per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory per 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 - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
