Radeon RX 480 vs Radeon RX 6600

Intro

The Radeon RX 480 features a GPU clock speed of 1120 MHz, and the 8192 MB of GDDR5 RAM runs at 2000 MHz through a 256-bit bus. It also is comprised of 2304 Stream Processors, 144 TAUs, and 32 ROPs.

Compare those specs to the Radeon RX 6600, which makes use of a 7 nm design. AMD has set the core speed at 1626 MHz. The GDDR6 memory runs at a speed of 1750 MHz on this card. It features 1792 SPUs along with 112 TAUs and 64 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its 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 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 rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
