Radeon Pro Duo vs Radeon RX 6800

Intro

Compare all of that to the Radeon RX 6800, which makes use of a 7 nm design. AMD has set the core speed at 1700 MHz. The GDDR6 RAM is set to run at a frequency of 2000 MHz on this card. It features 3840 SPUs along with 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

Theoretically speaking, the Radeon Pro Duo should perform quite a bit faster than the Radeon RX 6800 in general. (explain)

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

Texel Rate

The Radeon Pro Duo is much (approximately 25%) better at AF 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 should be much (more or less 28%) more effective at full screen anti-aliasing than the Radeon Pro Duo, and also will be capable of handling higher resolutions better. (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: Bandwidth is the max amount of information (measured in megabytes per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock 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 one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel 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 max fill rate.
