Radeon RX 480 4GB vs Radeon RX 6600

Intro

Compare those specs to the Radeon RX 6600, which comes with a GPU core clock speed of 1626 MHz, and 8192 MB of GDDR6 memory set to run at 1750 MHz through a 128-bit bus. It also is made up of 1792 SPUs, 112 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600		132 Watts
Radeon RX 480 4GB		150 Watts
	Difference: 18 Watts (14%)

Memory Bandwidth

Both cards have the exact same memory bandwidth, so in theory they should perform the same. (explain)

Texel Rate

The Radeon RX 6600 is a little bit (about 13%) more effective at texture filtering than the Radeon RX 480 4GB. (explain)

Radeon RX 6600		182112 Mtexels/sec
Radeon RX 480 4GB		161280 Mtexels/sec
	Difference: 20832 (13%)

Pixel Rate

The Radeon RX 6600 will be quite a bit (more or less 190%) better at AA than the Radeon RX 480 4GB, and also capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 6600		104064 Mpixels/sec
Radeon RX 480 4GB		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 max amount of data (measured in megabytes per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the 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 most pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
