Radeon Pro Duo vs Radeon RX 6900 XT

Intro

Compare those specs to the Radeon RX 6900 XT, which comes with GPU clock speed of 1825 MHz, and 16384 MB of GDDR6 memory running at 2000 MHz through a 256-bit bus. It also is comprised of 5120 SPUs, 320 TAUs, and 128 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6900 XT		300 Watts
Radeon Pro Duo		350 Watts
	Difference: 50 Watts (17%)

Memory Bandwidth

In theory, the Radeon Pro Duo should be quite a bit faster than the Radeon RX 6900 XT overall. (explain)

Radeon Pro Duo		1024000 MB/sec
Radeon RX 6900 XT		524288 MB/sec
	Difference: 499712 (95%)

Texel Rate

The Radeon RX 6900 XT will be just a bit (more or less 14%) better at texture filtering than the Radeon Pro Duo. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
Radeon Pro Duo		512000 Mtexels/sec
	Difference: 72000 (14%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 6900 XT is a better choice, and very much so. (explain)

Radeon RX 6900 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: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video 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 maximum amount of pixels that the graphics card could possibly record to the local memory in one 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 - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on 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 reach the maximum fill rate.
