Radeon Pro Duo vs Radeon RX 7900 XTX

Intro

Compare that to the Radeon RX 7900 XTX, which makes use of a 5 nm design. AMD has set the core speed at 1855 MHz. The GDDR6 memory is set to run at a frequency of 2500 MHz on this particular model. It features 6144 SPUs as well as 384 Texture Address Units and 192 ROPs.

Radeon Pro Duo		350 Watts
Radeon RX 7900 XTX		355 Watts
	Difference: 5 Watts (1%)

Memory Bandwidth

Theoretically speaking, the Radeon Pro Duo will be 4% quicker than the Radeon RX 7900 XTX overall, because of its higher data rate. (explain)

Radeon Pro Duo		1024000 MB/sec
Radeon RX 7900 XTX		983040 MB/sec
	Difference: 40960 (4%)

Texel Rate

The Radeon RX 7900 XTX will be a lot (more or less 39%) faster with regards to anisotropic filtering than the Radeon Pro Duo. (explain)

Radeon RX 7900 XTX		712320 Mtexels/sec
Radeon Pro Duo		512000 Mtexels/sec
	Difference: 200320 (39%)

Pixel Rate

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

Radeon RX 7900 XTX		356160 Mpixels/sec
Radeon Pro Duo		128000 Mpixels/sec
	Difference: 228160 (178%)

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 information (measured in MB per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units of the card by the core 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
