Radeon RX 570		229376 MB/sec
	Difference: 294912 (129%)

Texel Rate

The Radeon RX 6800 XT should be quite a bit (about 252%) more effective at texture filtering than the Radeon RX 570. (explain)

Radeon RX 6800 XT		525600 Mtexels/sec
Radeon RX 570		149504 Mtexels/sec
	Difference: 376096 (252%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 6800 XT is superior to the Radeon RX 570, and very much so. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
Radeon RX 570		37376 Mpixels/sec
	Difference: 196224 (525%)

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 max amount of data (measured in megabytes per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units by the core clock 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
