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 frequency at 1350 MHz. The GDDR6 memory is set to run at a frequency of 14 MHz on this specific card. It features 4352 SPUs along with 272 Texture Address Units and 88 ROPs.

Compare those specs to the Radeon RX Vega 56, which features GPU clock speed of 1156 MHz, and 8192 MB of HBM2 RAM running at 1600 MHz through a 2048-bit bus. It also features 3584 Stream Processors, 224 TAUs, and 64 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of MB per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the 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 applied per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number 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 rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
