Radeon Pro Duo vs Radeon RX 6950 XT

Intro

Compare all that to the Radeon RX 6950 XT, which comes with a clock speed of 1925 MHz and a GDDR6 memory frequency of 2250 MHz. It also makes use of a 256-bit memory bus, and uses a 7 nm design. It is comprised of 5120 SPUs, 320 Texture Address Units, and 128 Raster Operation Units.

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% faster than the Radeon RX 6950 XT overall, because of its higher bandwidth. (explain)

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

Texel Rate

The Radeon RX 6950 XT should be a little bit (more or less 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 superior to the Radeon Pro Duo, by far. (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: Memory bandwidth is the max amount of data (counted in MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the 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 amount of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. 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 is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
