Radeon HD 5970 vs Radeon RX 590

Intro

The Radeon HD 5970 comes with a GPU clock speed of 725 MHz, and the 1024 MB of GDDR5 RAM runs at 1000 MHz through a 256-bit bus. It also is comprised of 1600 Stream Processors, 160 TAUs, and 64 ROPs.

Compare those specs to the Radeon RX 590, which has a clock frequency of 1469 MHz and a GDDR5 memory frequency of 2000 MHz. It also features a 256-bit memory bus, and makes use of a 12 nm design. It features 2304 SPUs, 144 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 590 175 Watts
Radeon HD 5970 294 Watts
Difference: 119 Watts (68%)

Memory Bandwidth

Theoretically, the Radeon RX 590 should perform a bit faster than the Radeon HD 5970 in general. (explain)

Radeon RX 590 262144 MB/sec
Radeon HD 5970 256000 MB/sec
Difference: 6144 (2%)

Texel Rate

The Radeon HD 5970 is just a bit (more or less 10%) more effective at texture filtering than the Radeon RX 590. (explain)

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

Pixel Rate

The Radeon HD 5970 should be quite a bit (more or less 97%) more effective at full screen anti-aliasing than the Radeon RX 590, and should be able to handle higher resolutions without slowing down too much. (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 largest amount of data (counted in megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster 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 are processed in one second. This is worked out 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number 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 output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
