Radeon Pro Duo vs Radeon RX 6800 XT

Intro

Compare those specs to the Radeon RX 6800 XT, which features core clock speeds of 1825 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 RAM. It features 4608 SPUs along with 288 Texture Address Units and 128 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6800 XT		300 Watts
Radeon Pro Duo		350 Watts
	Difference: 50 Watts (17%)

Memory Bandwidth

The Radeon Pro Duo, in theory, should perform a lot faster than the Radeon RX 6800 XT in general. (explain)

Radeon Pro Duo		1024000 MB/sec
Radeon RX 6800 XT		524288 MB/sec
	Difference: 499712 (95%)

Texel Rate

The Radeon RX 6800 XT should be a little 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

The Radeon RX 6800 XT will be quite a bit (about 83%) faster with regards to AA than the Radeon Pro Duo, and should be capable of handling higher screen resolutions better. (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: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
