Radeon RX 560 vs Radeon RX 6800 XT

Intro

Compare those specs to the Radeon RX 6800 XT, which comes with GPU clock speed of 1825 MHz, and 16384 MB of GDDR6 RAM running at 2000 MHz through a 256-bit bus. It also is comprised of 4608 Stream Processors, 288 Texture Address Units, and 128 ROPs.

Radeon RX 560		75200 Mtexels/sec
	Difference: 450400 (599%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6800 XT is the winner, by a large margin. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
Radeon RX 560		18800 Mpixels/sec
	Difference: 214800 (1143%)

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 information (measured in MB per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video 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 most pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
