Radeon Pro Duo vs Radeon RX 5700 XT

Intro

The Radeon Pro Duo has a GPU core clock speed of 1000 MHz, and the 4096 MB of HBM memory is set to run at 500 MHz through a 4096-bit bus. It also features 4096 SPUs, 256 TAUs, and 64 ROPs.

Compare all that to the Radeon RX 5700 XT, which comes with a core clock frequency of 1605 MHz and a GDDR6 memory speed of 14000 MHz. It also features a 256-bit memory bus, and makes use of a 7 nm design. It is made up of 2560 SPUs, 160 Texture Address Units, and 64 Raster Operation Units.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the interface 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 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 applied per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at 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 that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
