Radeon RX 5700 XT vs Radeon RX Vega 64

Intro

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

Compare those specs to the Radeon RX Vega 64, which features a clock speed of 1247 MHz and a HBM2 memory speed of 1890 MHz. It also uses a 2048-bit memory bus, and uses a 14 nm design. It is made up of 4096 SPUs, 256 TAUs, and 64 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be moved past the external memory interface in 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 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 can be applied per second. This figure is worked out by multiplying the total number of texture units by the core 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
