Radeon Pro Duo vs Radeon RX 6800 XT

Intro

Compare all that to the Radeon RX 6800 XT, which has a core clock speed of 1825 MHz and a GDDR6 memory speed of 2000 MHz. It also features a 256-bit bus, and uses a 7 nm design. It is made up of 4608 SPUs, 288 TAUs, and 128 ROPs.

Radeon RX 6800 XT		524288 MB/sec
	Difference: 499712 (95%)

Texel Rate

The Radeon RX 6800 XT is a bit (more or less 3%) better at texture filtering than the Radeon Pro Duo. (explain)

Radeon RX 6800 XT		525600 Mtexels/sec
Radeon Pro Duo		512000 Mtexels/sec
	Difference: 13600 (3%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6800 XT is the winner, by far. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
Radeon Pro Duo		128000 Mpixels/sec
	Difference: 105600 (83%)

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 maximum amount of data (counted in megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units of the card 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 processed in a second.

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