Radeon RX 470 vs Radeon RX 5500

Intro

The Radeon RX 470 comes with a clock speed of 926 MHz and a GDDR5 memory speed of 1650 MHz. It also uses a 256-bit memory bus, and makes use of a 14 nm design. It features 2048 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Compare those specifications to the Radeon RX 5500, which has core speeds of 1670 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR6 RAM. It features 1408 SPUs as well as 88 Texture Address Units and 32 ROPs.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (counted in MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better 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 can be applied per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs 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 fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
