Radeon HD 5970 vs Radeon RX 590

Intro

The Radeon HD 5970 has a GPU core speed of 725 MHz, and the 1024 MB of GDDR5 memory is set to run at 1000 MHz through a 256-bit bus. It also is comprised of 1600 Stream Processors, 160 Texture Address Units, and 64 ROPs.

Compare all that to the Radeon RX 590, which comes with a clock speed of 1469 MHz and a GDDR5 memory frequency of 2000 MHz. It also uses a 256-bit memory bus, and uses a 12 nm design. It is made up of 2304 SPUs, 144 Texture Address Units, and 32 ROPs.

Radeon HD 5970 256000 MB/sec
Difference: 6144 (2%)

Texel Rate

The Radeon HD 5970 is a little bit (more or less 10%) faster with regards to AF than the Radeon RX 590. (explain)

Radeon HD 5970 232000 Mtexels/sec
Radeon RX 590 211536 Mtexels/sec
Difference: 20464 (10%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon HD 5970 is the winner, and very much so. (explain)

Radeon HD 5970 92800 Mpixels/sec
Radeon RX 590 47008 Mpixels/sec
Difference: 45792 (97%)

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 max amount of information (counted in megabytes per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in one 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 - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
