Radeon Pro Duo vs Radeon RX 7900 XT

Intro

Compare 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 particular card. It features 5376 SPUs as well as 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 will be 25% quicker than the Radeon RX 7900 XT overall, due to its greater data rate. (explain)

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

Texel Rate

The Radeon Pro Duo is a little bit (about 2%) more effective at AF 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 far. (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: Memory bandwidth is the max amount of information (in units of MB per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 applied in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill 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 ability to reach the max fill rate.
