VS

Radeon Pro Duo vs Radeon RX 6500 XT

Intro

The Radeon Pro Duo comes with a GPU core clock speed of 1000 MHz, and the 4096 MB of HBM RAM is set to run at 500 MHz through a 4096-bit bus. It also is made up of 4096 SPUs, 256 TAUs, and 64 ROPs.

Compare those specs to the Radeon RX 6500 XT, which makes use of a 6 nm design. AMD has clocked the core frequency at 2200 MHz. The GDDR6 memory runs at a frequency of 2250 MHz on this specific card. It features 1024 SPUs as well as 64 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6500 XT 107 Watts
Radeon Pro Duo 350 Watts
Difference: 243 Watts (227%)

Memory Bandwidth

As far as performance goes, the Radeon Pro Duo should in theory be a lot better than the Radeon RX 6500 XT overall. (explain)

Radeon Pro Duo 1024000 MB/sec
Radeon RX 6500 XT 147456 MB/sec
Difference: 876544 (594%)

Texel Rate

The Radeon Pro Duo is much (about 264%) better at anisotropic filtering than the Radeon RX 6500 XT. (explain)

Radeon Pro Duo 512000 Mtexels/sec
Radeon RX 6500 XT 140800 Mtexels/sec
Difference: 371200 (264%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon Pro Duo is a better choice, by a large margin. (explain)

Radeon Pro Duo 128000 Mpixels/sec
Radeon RX 6500 XT 70400 Mpixels/sec
Difference: 57600 (82%)

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: Bandwidth is the max amount of information (measured in megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
