Radeon Pro Duo vs Radeon RX 7900 XTX

Intro

Compare those specifications 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 runs at a speed of 2500 MHz on this model. It features 6144 SPUs as well as 384 TAUs and 192 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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% faster than the Radeon RX 7900 XTX in general, because of its higher bandwidth. (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 quite a bit (more or less 39%) better at texture 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 running with a high resolution is important to you, then the Radeon RX 7900 XTX is the winner, and very much so. (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: Bandwidth is the max amount of data (counted in megabytes per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR 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 number of texture units by the core clock 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
