Radeon R9 390X 8G vs Radeon RX 5700 XT 50th Anniversary Edition

Intro

The Radeon R9 390X 8G has a GPU core clock 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 made up of 2816 SPUs, 176 TAUs, and 64 ROPs.

Compare those specs to the Radeon RX 5700 XT 50th Anniversary Edition, which comes with core speeds of 1680 MHz on the GPU, and 14000 MHz on the 8096 MB of GDDR6 memory. It features 2560 SPUs as well as 160 Texture Address Units and 64 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 in one second. This number is worked out by multiplying the total amount of texture units by the core clock 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 in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated 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 quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
