Radeon Pro Duo vs Radeon RX 7900 XTX

Intro

Compare that to the Radeon RX 7900 XTX, which uses a 5 nm design. AMD has set the core frequency at 1855 MHz. The GDDR6 memory works at a frequency of 2500 MHz on this model. It features 6144 SPUs along with 384 Texture Address Units 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, the Radeon Pro Duo should perform just a bit faster than the Radeon RX 7900 XTX overall. (explain)

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

Texel Rate

The Radeon RX 7900 XTX should be a lot (more or less 39%) faster with regards to 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

The Radeon RX 7900 XTX is a lot (more or less 178%) better at FSAA than the Radeon Pro Duo, and should be capable of handling higher resolutions without slowing down too much. (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 (in units of megabytes per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling 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 chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. 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 lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
