Radeon RX 5700 XT vs Radeon RX Vega 56

Intro

The Radeon RX 5700 XT makes use of a 7 nm design. AMD has set the core speed at 1605 MHz. The GDDR6 RAM works at a frequency of 14000 MHz on this specific model. It features 2560 SPUs as well as 160 TAUs and 64 ROPs.

Compare all that to the Radeon RX Vega 56, which has clock speeds of 1156 MHz on the GPU, and 1600 MHz on the 8192 MB of HBM2 RAM. It features 3584 SPUs as well as 224 Texture Address Units and 64 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 applied per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
