GeForce GTX 980 Ti vs GeForce RTX 2080 SUPER

Intro

Compare those specifications to the GeForce RTX 2080 SUPER, which uses a 12 nm design. nVidia has clocked the core speed at 1650 MHz. The GDDR6 memory is set to run at a speed of 1937 MHz on this particular card. It features 3072 SPUs along with 192 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically, the GeForce RTX 2080 SUPER should be quite a bit faster than the GeForce GTX 980 Ti overall. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
GeForce GTX 980 Ti		336000 MB/sec
	Difference: 171904 (51%)

Texel Rate

The GeForce RTX 2080 SUPER is quite a bit (about 80%) faster with regards to texture filtering than the GeForce GTX 980 Ti. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce GTX 980 Ti		176000 Mtexels/sec
	Difference: 140800 (80%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce RTX 2080 SUPER is a better choice, though only just barely. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
GeForce GTX 980 Ti		96000 Mpixels/sec
	Difference: 9600 (10%)

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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
