GeForce RTX 2080 vs Radeon RX Vega 64

Intro

The GeForce RTX 2080 makes use of a 12 nm design. nVidia has set the core speed at 1515 MHz. The GDDR6 RAM is set to run at a speed of 14 MHz on this specific model. It features 2944 SPUs as well as 184 Texture Address Units and 64 Rasterization Operator Units.

Compare all of that to the Radeon RX Vega 64, which has GPU clock speed of 1247 MHz, and 8192 MB of HBM2 RAM set to run at 1890 MHz through a 2048-bit bus. It also is made up of 4096 Stream Processors, 256 Texture Address Units, and 64 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, 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 amount of pixels the graphics card can possibly write to the 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 clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
