Radeon HD 5970 vs Radeon RX 590

Intro

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

Compare that to the Radeon RX 590, which features GPU core speed of 1469 MHz, and 8192 MB of GDDR5 RAM running at 2000 MHz through a 256-bit bus. It also is comprised of 2304 Stream Processors, 144 TAUs, and 32 Raster Operation Units.

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

Pixel Rate

If running with a high 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: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at 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 write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
