Radeon R9 390X 8G vs Radeon RX 550

Intro

The Radeon R9 390X 8G has a GPU core speed of 1050 MHz, and the 8192 MB of GDDR5 RAM is set to run at 1500 MHz through a 512-bit bus. It also is comprised of 2816 Stream Processors, 176 TAUs, and 64 ROPs.

Compare all that to the Radeon RX 550, which has core speeds of 1100 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 RAM. It features 512 SPUs along with 32 TAUs and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in MB per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
