Radeon RX 480 4GB vs Radeon RX 6600 XT

Intro

The Radeon RX 480 4GB uses a 14 nm design. AMD has set the core speed at 1120 MHz. The GDDR5 memory works at a frequency of 1750 MHz on this specific card. It features 2304 SPUs as well as 144 TAUs and 32 ROPs.

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

Radeon RX 6600 XT 262144 MB/sec
Radeon RX 480 4GB 229376 MB/sec
Difference: 32768 (14%)

Texel Rate

The Radeon RX 6600 XT is quite a bit (approximately 56%) better at texture 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

If running with a high resolution is important to you, then the Radeon RX 6600 XT is a better choice, and very much so. (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.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once 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 AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics 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 amount of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel 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.
