GeForce GTX 980 vs GeForce RTX 2080

Intro

The GeForce GTX 980 uses a 28 nm design. nVidia has set the core frequency at 1126 MHz. The GDDR5 RAM works at a speed of 1750 MHz on this model. It features 2048 SPUs as well as 128 TAUs and 64 Rasterization Operator Units.

Compare those specifications to the GeForce RTX 2080, which comes with a GPU core clock speed of 1515 MHz, and 8192 MB of GDDR6 RAM set to run at 14 MHz through a 256-bit bus. It also is comprised of 2944 SPUs, 184 Texture Address Units, and 64 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core 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 rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
