GeForce RTX 2080 SUPER vs Radeon RX 6600 XT

Intro

Compare that to the Radeon RX 6600 XT, which comes with GPU core speed of 1968 MHz, and 8192 MB of GDDR6 memory set to run at 2000 MHz through a 128-bit bus. It also is comprised of 2048 SPUs, 128 TAUs, and 64 ROPs.

Radeon RX 6600 XT		251904 Mtexels/sec
	Difference: 64896 (26%)

Pixel Rate

The Radeon RX 6600 XT will be a small bit (approximately 19%) more effective at AA than the GeForce RTX 2080 SUPER, and should be capable of handling higher screen resolutions better. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
GeForce RTX 2080 SUPER		105600 Mpixels/sec
	Difference: 20352 (19%)

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 data (counted in megabytes per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If 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 texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
