Radeon RX 480 4GB vs Radeon RX 6600 XT

Intro

Compare all of that to the Radeon RX 6600 XT, which comes with core clock speeds of 1968 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR6 RAM. It features 2048 SPUs as well as 128 Texture Address Units and 64 Rasterization Operator Units.

The Radeon RX 6600 XT is much (more or less 56%) faster with regards to anisotropic filtering than the Radeon RX 480 4GB. (explain)

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 a lot (about 251%) faster with regards to AA than the Radeon RX 480 4GB, and will be capable of handling 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 largest amount of data (in units of megabytes per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster 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 applied per second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
