GeForce RTX 2080 vs Radeon RX Vega 64

Intro

The GeForce RTX 2080 comes with a GPU clock speed of 1515 MHz, and the 8192 MB of GDDR6 memory is set to run at 14 MHz through a 256-bit bus. It also is comprised of 2944 SPUs, 184 TAUs, and 64 Raster Operation Units.

Compare all that to the Radeon RX Vega 64, which has a clock speed of 1247 MHz and a HBM2 memory frequency of 1890 MHz. It also features a 2048-bit bus, and uses a 14 nm design. It is comprised of 4096 SPUs, 256 TAUs, and 64 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of information (counted in MB per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
