Radeon Pro Duo vs Radeon RX 6750 XT

Intro

The Radeon Pro Duo comes with a core clock frequency of 1000 MHz and a HBM memory frequency of 500 MHz. It also makes use of a 4096-bit memory bus, and makes use of a 28 nm design. It features 4096 SPUs, 256 Texture Address Units, and 64 Raster Operation Units.

Compare all of that to the Radeon RX 6750 XT, which features a GPU core clock speed of 2150 MHz, and 12288 MB of GDDR6 RAM set to run at 2250 MHz through a 192-bit bus. It also is comprised of 2560 Stream Processors, 160 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6750 XT 250 Watts
Radeon Pro Duo 350 Watts
Difference: 100 Watts (40%)

Memory Bandwidth

Performance-wise, the Radeon Pro Duo should theoretically be quite a bit better than the Radeon RX 6750 XT overall. (explain)

Radeon Pro Duo 1024000 MB/sec
Radeon RX 6750 XT 442368 MB/sec
Difference: 581632 (131%)

Texel Rate

The Radeon Pro Duo is a lot (more or less 49%) faster with regards to anisotropic filtering than the Radeon RX 6750 XT. (explain)

Radeon Pro Duo 512000 Mtexels/sec
Radeon RX 6750 XT 344000 Mtexels/sec
Difference: 168000 (49%)

Pixel Rate

The Radeon RX 6750 XT will be a bit (about 8%) better at FSAA than the Radeon Pro Duo, and also will be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 6750 XT 137600 Mpixels/sec
Radeon Pro Duo 128000 Mpixels/sec
Difference: 9600 (8%)

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 max amount of data (in units of 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 the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
