Radeon Pro Duo vs Radeon RX 6800

Intro

Compare those specifications to the Radeon RX 6800, which uses a 7 nm design. AMD has set the core frequency at 1700 MHz. The GDDR6 memory works at a frequency of 2000 MHz on this specific card. It features 3840 SPUs as well as 240 TAUs and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6800		250 Watts
Radeon Pro Duo		350 Watts
	Difference: 100 Watts (40%)

Memory Bandwidth

In theory, the Radeon Pro Duo should be 95% quicker than the Radeon RX 6800 overall, because of its higher bandwidth. (explain)

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

Texel Rate

The Radeon Pro Duo will be a lot (more or less 25%) more effective at anisotropic filtering than the Radeon RX 6800. (explain)

Radeon Pro Duo		512000 Mtexels/sec
Radeon RX 6800		408000 Mtexels/sec
	Difference: 104000 (25%)

Pixel Rate

The Radeon RX 6800 will be a lot (about 28%) faster with regards to FSAA than the Radeon Pro Duo, and should be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon RX 6800		163200 Mpixels/sec
Radeon Pro Duo		128000 Mpixels/sec
	Difference: 35200 (28%)

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 maximum amount of data (measured in MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the graphics 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 that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
