GeForce GTX 980 Ti vs GeForce RTX 2060 Super

Intro

Compare that to the GeForce RTX 2060 Super, which has a clock frequency of 1470 MHz and a GDDR6 memory frequency of 1750 MHz. It also makes use of a 256-bit memory bus, and uses a 12 nm design. It is made up of 2176 SPUs, 136 Texture Address Units, and 64 Raster Operation Units.

GeForce GTX 980 Ti		336000 MB/sec
	Difference: 122752 (37%)

Texel Rate

The GeForce RTX 2060 Super will be just a bit (approximately 14%) faster with regards to anisotropic filtering than the GeForce GTX 980 Ti. (explain)

GeForce RTX 2060 Super		199920 Mtexels/sec
GeForce GTX 980 Ti		176000 Mtexels/sec
	Difference: 23920 (14%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 980 Ti is a better choice, though only just barely. (explain)

GeForce GTX 980 Ti		96000 Mpixels/sec
GeForce RTX 2060 Super		94080 Mpixels/sec
	Difference: 1920 (2%)

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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's 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 are processed per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
