Radeon Pro Duo vs Radeon RX 590

Intro

Compare those specs to the Radeon RX 590, which has GPU core speed of 1469 MHz, and 8192 MB of GDDR5 memory set to run at 2000 MHz through a 256-bit bus. It also features 2304 SPUs, 144 Texture Address Units, and 32 ROPs.

Radeon RX 590		211536 Mtexels/sec
	Difference: 300464 (142%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon Pro Duo is superior to the Radeon RX 590, by far. (explain)

Radeon Pro Duo		128000 Mpixels/sec
Radeon RX 590		47008 Mpixels/sec
	Difference: 80992 (172%)

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: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
