Radeon Pro Duo vs Radeon RX 7900 XT

Intro

Compare those specifications to the Radeon RX 7900 XT, which features GPU core speed of 1500 MHz, and 20480 MB of GDDR6 RAM set to run at 2500 MHz through a 320-bit bus. It also is comprised of 5376 SPUs, 336 TAUs, and 192 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 7900 XT		300 Watts
Radeon Pro Duo		350 Watts
	Difference: 50 Watts (17%)

Memory Bandwidth

Theoretically speaking, the Radeon Pro Duo should be 25% quicker than the Radeon RX 7900 XT in general, due to its higher bandwidth. (explain)

Radeon Pro Duo		1024000 MB/sec
Radeon RX 7900 XT		819200 MB/sec
	Difference: 204800 (25%)

Texel Rate

The Radeon Pro Duo will be just a bit (more or less 2%) better at anisotropic 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 screen resolution is important to you, then the Radeon RX 7900 XT is the winner, and very much so. (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 maximum amount of data (measured in megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range 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 texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
