Radeon RX 5600 XT vs Radeon RX 6600

Intro

Compare all that to the Radeon RX 6600, which comes with core clock speeds of 1626 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 memory. 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 RX 5600 XT		160 Watts
	Difference: 28 Watts (21%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5600 XT should be quite a bit faster than the Radeon RX 6600 overall. (explain)

Radeon RX 5600 XT		344064 MB/sec
Radeon RX 6600		229376 MB/sec
	Difference: 114688 (50%)

Texel Rate

The Radeon RX 5600 XT should be a bit (more or less 9%) more effective at AF than the Radeon RX 6600. (explain)

Radeon RX 5600 XT		198000 Mtexels/sec
Radeon RX 6600		182112 Mtexels/sec
	Difference: 15888 (9%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 6600 is the winner, not by a very large margin though. (explain)

Radeon RX 6600		104064 Mpixels/sec
Radeon RX 5600 XT		88000 Mpixels/sec
	Difference: 16064 (18%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 processed per 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
