Radeon RX 5700 XT vs Radeon RX Vega 56

Intro

The Radeon RX 5700 XT comes with a GPU clock speed of 1605 MHz, and the 8096 MB of GDDR6 RAM is set to run at 14000 MHz through a 256-bit bus. It also features 2560 Stream Processors, 160 Texture Address Units, and 64 Raster Operation Units.

Compare that to the Radeon RX Vega 56, which features a GPU core clock speed of 1156 MHz, and 8192 MB of HBM2 memory running at 1600 MHz through a 2048-bit bus. It also is comprised of 3584 SPUs, 224 TAUs, and 64 ROPs.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, the result 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling 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 can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
