Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6950 XT		335 Watts
Radeon Pro Duo		350 Watts
	Difference: 15 Watts (4%)

Memory Bandwidth

Theoretically speaking, the Radeon Pro Duo should be 74% quicker than the Radeon RX 6950 XT in general, due to its higher data rate. (explain)

Radeon Pro Duo		1024000 MB/sec
Radeon RX 6950 XT		589824 MB/sec
	Difference: 434176 (74%)

Texel Rate

The Radeon RX 6950 XT is a little bit (approximately 20%) faster with regards to texture filtering than the Radeon Pro Duo. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
Radeon Pro Duo		512000 Mtexels/sec
	Difference: 104000 (20%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 6950 XT is the winner, by a large margin. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
Radeon Pro Duo		128000 Mpixels/sec
	Difference: 118400 (93%)

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 (counted in MB per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
