GeForce RTX 2080 vs Radeon RX Vega 56

Intro

The GeForce RTX 2080 makes use of a 12 nm design. nVidia has clocked the core speed at 1515 MHz. The GDDR6 RAM runs at a frequency of 14 MHz on this particular model. It features 2944 SPUs as well as 184 TAUs and 64 Rasterization Operator Units.

Compare those specifications to the Radeon RX Vega 56, which makes use of a 14 nm design. AMD has clocked the core frequency at 1156 MHz. The HBM2 RAM is set to run at a speed of 1600 MHz on this card. It features 3584 SPUs along with 224 Texture Address Units and 64 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 number of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total number of texture units of the card by the core clock 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 applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated 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 drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
