Radeon RX 580 vs Radeon RX 6600

Intro

The Radeon RX 580 comes with a clock speed of 1257 MHz and a GDDR5 memory frequency of 2000 MHz. It also features a 256-bit bus, and makes use of a 14 nm design. It features 2304 SPUs, 144 Texture Address Units, and 32 Raster Operation Units.

Compare all that to the Radeon RX 6600, which features a clock frequency of 1626 MHz and a GDDR6 memory speed of 1750 MHz. It also uses a 128-bit bus, and uses a 7 nm design. It is comprised of 1792 SPUs, 112 TAUs, and 64 ROPs.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (in units of megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 can be processed per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs 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 fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
