Radeon RX 5500 vs Radeon RX 580

Intro

The Radeon RX 5500 uses a 7 nm design. AMD has set the core speed at 1670 MHz. The GDDR6 RAM runs at a frequency of 14000 MHz on this particular card. It features 1408 SPUs as well as 88 TAUs and 32 ROPs.

Compare those specifications to the Radeon RX 580, which features clock speeds of 1257 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 RAM. It features 2304 SPUs as well as 144 TAUs and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount 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 processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units 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 rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
