Radeon Pro Duo vs Radeon RX 590

Intro

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

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

Pixel Rate

The Radeon Pro Duo should be much (about 172%) faster with regards to FSAA than the Radeon RX 590, and also should be able to handle higher resolutions more effectively. (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: Bandwidth is the max amount of information (counted in MB per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
