GeForce GTX 980 vs GeForce RTX 2080

Intro

The GeForce GTX 980 comes with a GPU clock speed of 1126 MHz, and the 4096 MB of GDDR5 RAM is set to run at 1750 MHz through a 256-bit bus. It also is comprised of 2048 SPUs, 128 TAUs, and 64 ROPs.

Compare all of that to the GeForce RTX 2080, which has a core clock speed of 1515 MHz and a GDDR6 memory speed of 14 MHz. It also uses a 256-bit bus, and makes use of a 12 nm design. It features 2944 SPUs, 184 TAUs, and 64 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, 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 maximum amount of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka 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 of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
