GeForce RTX 2080 Ti vs Radeon RX Vega 56

Intro

The GeForce RTX 2080 Ti uses a 12 nm design. nVidia has clocked the core speed at 1350 MHz. The GDDR6 memory runs at a speed of 14 MHz on this card. It features 4352 SPUs along with 272 Texture Address Units and 88 ROPs.

Compare those specs to the Radeon RX Vega 56, which uses a 14 nm design. AMD has clocked the core speed at 1156 MHz. The HBM2 memory works at a speed of 1600 MHz on this particular model. It features 3584 SPUs along with 224 TAUs and 64 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units by the core 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 applied per second.

Pixel Rate: Pixel rate is the most pixels the video card can 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 colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
