GeForce RTX 3080 Ti vs Radeon RX 6600 XT

Intro

Compare those specifications to the Radeon RX 6600 XT, which uses a 7 nm design. AMD has set the core speed at 1968 MHz. The GDDR6 RAM runs at a speed of 2000 MHz on this specific card. It features 2048 SPUs as well as 128 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600 XT		160 Watts
GeForce RTX 3080 Ti		350 Watts
	Difference: 190 Watts (119%)

Memory Bandwidth

The GeForce RTX 3080 Ti should theoretically perform quite a bit faster than the Radeon RX 6600 XT in general. (explain)

GeForce RTX 3080 Ti		934297 MB/sec
Radeon RX 6600 XT		262144 MB/sec
	Difference: 672153 (256%)

Texel Rate

The GeForce RTX 3080 Ti will be quite a bit (approximately 73%) faster with regards to AF than the Radeon RX 6600 XT. (explain)

GeForce RTX 3080 Ti		436800 Mtexels/sec
Radeon RX 6600 XT		251904 Mtexels/sec
	Difference: 184896 (73%)

Pixel Rate

The GeForce RTX 3080 Ti is much (more or less 21%) faster with regards to full screen anti-aliasing than the Radeon RX 6600 XT, and should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
Radeon RX 6600 XT		125952 Mpixels/sec
	Difference: 26928 (21%)

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 largest amount of data (measured in megabytes per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's 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 amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the 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 most pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
