Radeon RX 6600 vs Radeon RX 6600 XT

Intro

The Radeon RX 6600 features core speeds of 1626 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 RAM. It features 1792 SPUs as well as 112 TAUs and 64 Rasterization Operator Units.

Compare those specs to the Radeon RX 6600 XT, which has a GPU core clock speed of 1968 MHz, and 8192 MB of GDDR6 RAM running at 2000 MHz through a 128-bit bus. It also is made up of 2048 Stream Processors, 128 TAUs, and 64 ROPs.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units by the core 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
