Radeon Pro Duo vs Radeon RX 580

Intro

Compare all of that to the Radeon RX 580, which has core speeds of 1257 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 RAM. It features 2304 SPUs as well as 144 TAUs and 32 Rasterization Operator Units.

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

Texel Rate

The Radeon Pro Duo is a lot (more or less 183%) better at anisotropic 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 running with lots of anti-aliasing is important to you, then the Radeon Pro Duo is superior to the Radeon RX 580, by a large margin. (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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once 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 anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units by the core clock 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 applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. 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 fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
