Radeon Pro Duo vs Radeon RX 580

Intro

The Radeon Pro Duo comes with a GPU core speed of 1000 MHz, and the 4096 MB of HBM memory is set to run at 500 MHz through a 4096-bit bus. It also features 4096 SPUs, 256 Texture Address Units, and 64 Raster Operation Units.

Compare that to the Radeon RX 580, which comes with a clock speed of 1257 MHz and a GDDR5 memory speed of 2000 MHz. It also uses a 256-bit memory bus, and makes use of a 14 nm design. It is made up of 2304 SPUs, 144 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 580 185 Watts
Radeon Pro Duo 350 Watts
Difference: 165 Watts (89%)

Memory Bandwidth

The Radeon Pro Duo should in theory perform quite a bit faster than the Radeon RX 580 in general. (explain)

Radeon Pro Duo 1024000 MB/sec
Radeon RX 580 262144 MB/sec
Difference: 761856 (291%)

Texel Rate

The Radeon Pro Duo will be a lot (more or less 183%) more effective at texture filtering than the Radeon RX 580. (explain)

Radeon Pro Duo 512000 Mtexels/sec
Radeon RX 580 181008 Mtexels/sec
Difference: 330992 (183%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon Pro Duo is the winner, by far. (explain)

Radeon Pro Duo 128000 Mpixels/sec
Radeon RX 580 40224 Mpixels/sec
Difference: 87776 (218%)

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 maximum amount of information (measured in megabytes per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock 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 most pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The number 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 outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
