Radeon RX 480 vs Radeon RX 6600

Intro

The Radeon RX 480 features core clock speeds of 1120 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 RAM. It features 2304 SPUs along with 144 TAUs and 32 Rasterization Operator Units.

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

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

Pixel Rate

The Radeon RX 6600 will be much (more or less 190%) faster with regards to AA than the Radeon RX 480, and also will be able to handle higher screen resolutions while still performing well. (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.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output 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 reach the max fill rate.
