Radeon RX 470		211200 MB/sec
	Difference: 50944 (24%)

Texel Rate

The Radeon RX 6600 XT will be a lot (more or less 113%) better at AF than the Radeon RX 470. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
Radeon RX 470		118528 Mtexels/sec
	Difference: 133376 (113%)

Pixel Rate

The Radeon RX 6600 XT will be a lot (more or less 325%) faster with regards to FSAA than the Radeon RX 470, and should be capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
Radeon RX 470		29632 Mpixels/sec
	Difference: 96320 (325%)

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 max amount of data (measured in megabytes per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
