GeForce RTX 2080 Ti vs Radeon RX 6600 XT

Intro

Compare all of that to the Radeon RX 6600 XT, which features clock speeds of 1968 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR6 RAM. It features 2048 SPUs as well as 128 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the GeForce RTX 2080 Ti should be 141% quicker than the Radeon RX 6600 XT in general, because of its greater bandwidth. (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 a lot (more or less 46%) faster with regards to texture 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

If using high levels of AA is important to you, then the Radeon RX 6600 XT is superior to the GeForce RTX 2080 Ti, though not by far. (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 maximum amount of data (counted in MB per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics 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 maximum number of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
