GeForce RTX 2080 Ti vs Radeon RX 6600 XT

Intro

Compare that to the Radeon RX 6600 XT, which features a clock frequency of 1968 MHz and a GDDR6 memory speed of 2000 MHz. It also uses a 128-bit bus, and makes use of a 7 nm design. It is made up of 2048 SPUs, 128 Texture Address Units, and 64 Raster Operation Units.

Radeon RX 6600 XT		160 Watts
GeForce RTX 2080 Ti		250 Watts
	Difference: 90 Watts (56%)

Memory Bandwidth

Theoretically, the GeForce RTX 2080 Ti should be a lot faster than the Radeon RX 6600 XT overall. (explain)

GeForce RTX 2080 Ti		630784 MB/sec
Radeon RX 6600 XT		262144 MB/sec
	Difference: 368640 (141%)

Texel Rate

The GeForce RTX 2080 Ti is much (about 46%) better at anisotropic filtering than the Radeon RX 6600 XT. (explain)

GeForce RTX 2080 Ti		367200 Mtexels/sec
Radeon RX 6600 XT		251904 Mtexels/sec
	Difference: 115296 (46%)

Pixel Rate

The Radeon RX 6600 XT will be just a bit (more or less 6%) faster with regards to full screen anti-aliasing than the GeForce RTX 2080 Ti, and also should be able to handle higher resolutions better. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
GeForce RTX 2080 Ti		118800 Mpixels/sec
	Difference: 7152 (6%)

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 (counted in megabytes per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 applied in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling 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 can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out 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 drawing the pixels (image) on 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 ability to get to the maximum fill rate.
