Radeon RX 470 vs Radeon RX 6600

Intro

The Radeon RX 470 comes with core speeds of 926 MHz on the GPU, and 1650 MHz on the 8192 MB of GDDR5 RAM. It features 2048 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.

Compare those specifications to the Radeon RX 6600, which has a core clock frequency of 1626 MHz and a GDDR6 memory speed of 1750 MHz. It also makes use of a 128-bit bus, and makes use of a 7 nm design. It is comprised of 1792 SPUs, 112 TAUs, and 64 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (in units of megabytes per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, the result 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, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
