Radeon RX 480 4GB vs Radeon RX 6600 XT

Intro

Compare that to the Radeon RX 6600 XT, which has GPU core speed of 1968 MHz, and 8192 MB of GDDR6 memory set to run at 2000 MHz through a 128-bit bus. It also features 2048 Stream Processors, 128 Texture Address Units, and 64 Raster Operation Units.

Radeon RX 6600 XT		251904 Mtexels/sec
Radeon RX 480 4GB		161280 Mtexels/sec
	Difference: 90624 (56%)

Pixel Rate

The Radeon RX 6600 XT should be quite a bit (approximately 251%) more effective at AA than the Radeon RX 480 4GB, and also able to handle higher resolutions while still performing well. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
Radeon RX 480 4GB		35840 Mpixels/sec
	Difference: 90112 (251%)

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 information (measured in megabytes per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. 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 number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
