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 frequency at 1968 MHz. The GDDR6 RAM works at a speed of 2000 MHz on this model. It features 2048 SPUs as well as 128 Texture Address Units 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

In theory, the GeForce RTX 3080 Ti will be 256% quicker than the Radeon RX 6600 XT in general, because of its greater data rate. (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 a lot (about 73%) better at texture filtering 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 should be quite a bit (approximately 21%) better at AA than the Radeon RX 6600 XT, and also able to handle higher resolutions more effectively. (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: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the 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 texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
