Radeon RX 470 4GB		120 Watts
Radeon RX 6600 XT		160 Watts
	Difference: 40 Watts (33%)

Memory Bandwidth

In theory, the Radeon RX 6600 XT should perform quite a bit faster than the Radeon RX 470 4GB in general. (explain)

Radeon RX 6600 XT		262144 MB/sec
Radeon RX 470 4GB		211200 MB/sec
	Difference: 50944 (24%)

Texel Rate

The Radeon RX 6600 XT should be a lot (approximately 113%) more effective at anisotropic filtering than the Radeon RX 470 4GB. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
Radeon RX 470 4GB		118528 Mtexels/sec
	Difference: 133376 (113%)

Pixel Rate

The Radeon RX 6600 XT will be quite a bit (about 325%) faster with regards to full screen anti-aliasing than the Radeon RX 470 4GB, and also should be able to handle higher screen resolutions more effectively. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
Radeon RX 470 4GB		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 largest amount of data (counted in MB per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 can be applied in one second. This is calculated by multiplying the total texture units of the card 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
