Radeon Pro Duo vs Radeon RX 6600 XT

Intro

Compare all of that to the Radeon RX 6600 XT, which features a core clock frequency of 1968 MHz and a GDDR6 memory frequency of 2000 MHz. It also makes use of a 128-bit memory bus, and makes use of a 7 nm design. It is comprised of 2048 SPUs, 128 TAUs, and 64 Raster Operation Units.

Radeon RX 6600 XT		262144 MB/sec
	Difference: 761856 (291%)

Texel Rate

The Radeon Pro Duo will be a lot (more or less 103%) more effective at texture filtering than the Radeon RX 6600 XT. (explain)

Radeon Pro Duo		512000 Mtexels/sec
Radeon RX 6600 XT		251904 Mtexels/sec
	Difference: 260096 (103%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon Pro Duo is superior to the Radeon RX 6600 XT, though not by far. (explain)

Radeon Pro Duo		128000 Mpixels/sec
Radeon RX 6600 XT		125952 Mpixels/sec
	Difference: 2048 (2%)

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 information (measured in megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

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