Radeon Pro Duo vs Radeon RX 6800

Intro

Compare those specs to the Radeon RX 6800, which has a clock frequency of 1700 MHz and a GDDR6 memory speed of 2000 MHz. It also makes use of a 256-bit bus, and makes use of a 7 nm design. It is comprised of 3840 SPUs, 240 Texture Address Units, and 96 Raster Operation Units.

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

Memory Bandwidth

As far as performance goes, the Radeon Pro Duo should in theory be a lot better than the Radeon RX 6800 overall. (explain)

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

Texel Rate

The Radeon Pro Duo should be much (approximately 25%) more effective at texture filtering than the Radeon RX 6800. (explain)

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

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 6800 is the winner, by a large margin. (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 largest amount of information (counted in megabytes per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in a 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 - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on 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 max fill rate.
