Radeon Pro Duo vs Radeon RX 7900 XT

Intro

Compare all that to the Radeon RX 7900 XT, which has a clock speed of 1500 MHz and a GDDR6 memory frequency of 2500 MHz. It also makes use of a 320-bit bus, and uses a 5 nm design. It features 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

The Radeon Pro Duo, in theory, should perform much faster than the Radeon RX 7900 XT overall. (explain)

Radeon Pro Duo		1024000 MB/sec
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 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

The Radeon RX 7900 XT should be quite a bit (more or less 125%) more effective at FSAA than the Radeon Pro Duo, and also able to handle higher screen resolutions without slowing down too much. (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 max amount of information (in units of MB per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster 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 number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
