Radeon Pro Duo vs Radeon RX 6600

Intro

Compare that to the Radeon RX 6600, which uses a 7 nm design. AMD has set the core speed at 1626 MHz. The GDDR6 RAM runs at a speed of 1750 MHz on this model. It features 1792 SPUs as well as 112 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600		132 Watts
Radeon Pro Duo		350 Watts
	Difference: 218 Watts (165%)

Memory Bandwidth

Theoretically, the Radeon Pro Duo should perform a lot faster than the Radeon RX 6600 overall. (explain)

Radeon Pro Duo		1024000 MB/sec
Radeon RX 6600		229376 MB/sec
	Difference: 794624 (346%)

Texel Rate

The Radeon Pro Duo should be a lot (about 181%) better at texture filtering than the Radeon RX 6600. (explain)

Radeon Pro Duo		512000 Mtexels/sec
Radeon RX 6600		182112 Mtexels/sec
	Difference: 329888 (181%)

Pixel Rate

The Radeon Pro Duo will be much (about 23%) faster with regards to anti-aliasing than the Radeon RX 6600, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon Pro Duo		128000 Mpixels/sec
Radeon RX 6600		104064 Mpixels/sec
	Difference: 23936 (23%)

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 data (counted in MB per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it should 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 anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units by the core 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 in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
