Compare any two graphics cards:
VS

Radeon Pro Duo vs Radeon RX 6900 XT

Intro

The Radeon Pro Duo comes with a GPU clock speed of 1000 MHz, and the 4096 MB of HBM RAM runs at 500 MHz through a 4096-bit bus. It also features 4096 SPUs, 256 Texture Address Units, and 64 Raster Operation Units.

Compare those specs to the Radeon RX 6900 XT, which uses a 7 nm design. AMD has clocked the core speed at 1825 MHz. The GDDR6 RAM runs at a speed of 2000 MHz on this particular card. It features 5120 SPUs along with 320 TAUs and 128 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6900 XT 300 Watts
Radeon Pro Duo 350 Watts
Difference: 50 Watts (17%)

Memory Bandwidth

The Radeon Pro Duo should theoretically be much faster than the Radeon RX 6900 XT overall. (explain)

Radeon Pro Duo 1024000 MB/sec
Radeon RX 6900 XT 524288 MB/sec
Difference: 499712 (95%)

Texel Rate

The Radeon RX 6900 XT will be a bit (more or less 14%) more effective at anisotropic filtering than the Radeon Pro Duo. (explain)

Radeon RX 6900 XT 584000 Mtexels/sec
Radeon Pro Duo 512000 Mtexels/sec
Difference: 72000 (14%)

Pixel Rate

The Radeon RX 6900 XT is quite a bit (about 83%) more effective at full screen anti-aliasing than the Radeon Pro Duo, and should be able to handle higher resolutions better. (explain)

Radeon RX 6900 XT 233600 Mpixels/sec
Radeon Pro Duo 128000 Mpixels/sec
Difference: 105600 (83%)

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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, it must 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 anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
