Radeon Pro Duo vs Radeon RX 7900 XT

Intro

Compare all of that to the Radeon RX 7900 XT, which uses a 5 nm design. AMD has clocked the core frequency at 1500 MHz. The GDDR6 RAM is set to run at a frequency of 2500 MHz on this specific model. It features 5376 SPUs as well as 336 TAUs and 192 ROPs.

Radeon RX 7900 XT		819200 MB/sec
	Difference: 204800 (25%)

Texel Rate

The Radeon Pro Duo should be a little bit (approximately 2%) better at texture filtering than the Radeon RX 7900 XT. (explain)

Radeon Pro Duo		512000 Mtexels/sec
Radeon RX 7900 XT		504000 Mtexels/sec
	Difference: 8000 (2%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 7900 XT is a better choice, by a large margin. (explain)

Radeon RX 7900 XT		288000 Mpixels/sec
Radeon Pro Duo		128000 Mpixels/sec
	Difference: 160000 (125%)

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 largest amount of information (measured in MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock 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 rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
