GeForce GTX 980 Ti vs GeForce RTX 2080 Ti

Intro

The GeForce GTX 980 Ti has a GPU core clock speed of 1000 MHz, and the 6144 MB of GDDR5 RAM is set to run at 1750 MHz through a 384-bit bus. It also features 2816 SPUs, 176 Texture Address Units, and 96 Raster Operation Units.

Compare all of that to the GeForce RTX 2080 Ti, which comes with a clock frequency of 1350 MHz and a GDDR6 memory frequency of 14 MHz. It also uses a 352-bit bus, and uses a 12 nm design. It is comprised of 4352 SPUs, 272 TAUs, and 88 Raster Operation Units.

The GeForce RTX 2080 Ti should be quite a bit (approximately 109%) more effective at AF than the GeForce GTX 980 Ti. (explain)

GeForce RTX 2080 Ti 367200 Mtexels/sec
GeForce GTX 980 Ti 176000 Mtexels/sec
Difference: 191200 (109%)

Pixel Rate

The GeForce RTX 2080 Ti is much (more or less 24%) faster with regards to AA than the GeForce GTX 980 Ti, and capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce RTX 2080 Ti 118800 Mpixels/sec
GeForce GTX 980 Ti 96000 Mpixels/sec
Difference: 22800 (24%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the 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 amount of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
