GeForce RTX 2080 SUPER vs Radeon RX Vega 56

Intro

The GeForce RTX 2080 SUPER makes use of a 12 nm design. nVidia has clocked the core speed at 1650 MHz. The GDDR6 memory works at a speed of 1937 MHz on this specific card. It features 3072 SPUs along with 192 Texture Address Units and 64 Rasterization Operator Units.

Compare all that to the Radeon RX Vega 56, which features GPU core speed of 1156 MHz, and 8192 MB of HBM2 RAM set to run at 1600 MHz through a 2048-bit bus. It also features 3584 Stream Processors, 224 TAUs, and 64 ROPs.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at 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 chip could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
