Radeon HD 5970 vs Radeon RX 560

Intro

Compare that to the Radeon RX 560, which uses a 14 nm design. AMD has set the core speed at 1175 MHz. The GDDR5 RAM runs at a frequency of 1750 MHz on this specific 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
Radeon HD 5970		294 Watts
	Difference: 214 Watts (268%)

Memory Bandwidth

The Radeon HD 5970 should in theory be a lot faster than the Radeon RX 560 in general. (explain)

Radeon HD 5970		256000 MB/sec
Radeon RX 560		114688 MB/sec
	Difference: 141312 (123%)

Texel Rate

The Radeon HD 5970 should be quite a bit (more or less 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 is much (more or less 394%) more effective at FSAA than the Radeon RX 560, and should be capable of handling higher screen resolutions without losing too much performance. (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.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. 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 can be processed in one second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the video 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 graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
