Radeon RX 570		229376 MB/sec
	Difference: 32768 (14%)

Texel Rate

The Radeon RX 6600 XT should be a lot (more or less 68%) better at AF than the Radeon RX 570. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
Radeon RX 570		149504 Mtexels/sec
	Difference: 102400 (68%)

Pixel Rate

The Radeon RX 6600 XT should be much (more or less 237%) faster with regards to FSAA than the Radeon RX 570, and will be capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
Radeon RX 570		37376 Mpixels/sec
	Difference: 88576 (237%)

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 information (in units of megabytes per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 are processed in one second. This figure 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also 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 memory bandwidth is, the lower the potential to reach the maximum fill rate.
