VS

Radeon RX 5500 XT vs Radeon RX 6600 XT

Intro

The Radeon RX 5500 XT features a GPU core speed of 1717 MHz, and the 8192 MB of GDDR6 memory is set to run at 1750 MHz through a 128-bit bus. It also features 1408 Stream Processors, 88 TAUs, and 32 ROPs.

Compare those specs to the Radeon RX 6600 XT, which comes with GPU core speed of 1968 MHz, and 8192 MB of GDDR6 memory running at 2000 MHz through a 128-bit bus. It also is comprised of 2048 Stream Processors, 128 Texture Address Units, and 64 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
