Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600		132 Watts
Radeon RX 480		150 Watts
	Difference: 18 Watts (14%)

Memory Bandwidth

In theory, the Radeon RX 480 should be 14% faster than the Radeon RX 6600 in general, due to its higher data rate. (explain)

Radeon RX 480		262144 MB/sec
Radeon RX 6600		229376 MB/sec
	Difference: 32768 (14%)

Texel Rate

The Radeon RX 6600 will be just a bit (approximately 13%) better at texture filtering than the Radeon RX 480. (explain)

Radeon RX 6600		182112 Mtexels/sec
Radeon RX 480		161280 Mtexels/sec
	Difference: 20832 (13%)

Pixel Rate

The Radeon RX 6600 will be a lot (about 190%) better at AA than the Radeon RX 480, and should be capable of handling higher resolutions without slowing down too much. (explain)

Radeon RX 6600		104064 Mpixels/sec
Radeon RX 480		35840 Mpixels/sec
	Difference: 68224 (190%)

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 largest amount of data (in units of MB per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher 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 the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
