GeForce RTX 3080 12 GB vs Radeon RX 6600

Intro

Compare all of that to the Radeon RX 6600, which has 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.

GeForce RTX 3080 12 GB		934298 MB/sec
Radeon RX 6600		229376 MB/sec
	Difference: 704922 (307%)

Texel Rate

The GeForce RTX 3080 12 GB will be quite a bit (about 94%) faster with regards to texture filtering than the Radeon RX 6600. (explain)

GeForce RTX 3080 12 GB		352800 Mtexels/sec
Radeon RX 6600		182112 Mtexels/sec
	Difference: 170688 (94%)

Pixel Rate

The GeForce RTX 3080 12 GB will be much (more or less 36%) better at full screen anti-aliasing than the Radeon RX 6600, and capable of handling higher resolutions without slowing down too much. (explain)

GeForce RTX 3080 12 GB		141120 Mpixels/sec
Radeon RX 6600		104064 Mpixels/sec
	Difference: 37056 (36%)

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: Bandwidth is the max amount of information (measured in MB per second) that can be transported over the external memory interface in one second. It is worked out 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 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
