GeForce GTX 980 vs GeForce RTX 2080 SUPER

Intro

Compare those specifications to the GeForce RTX 2080 SUPER, which comes with clock speeds of 1650 MHz on the GPU, and 1937 MHz on the 8192 MB of GDDR6 memory. It features 3072 SPUs along with 192 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 980		165 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 85 Watts (52%)

Memory Bandwidth

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

GeForce RTX 2080 SUPER		507904 MB/sec
GeForce GTX 980		224000 MB/sec
	Difference: 283904 (127%)

Texel Rate

The GeForce RTX 2080 SUPER is a lot (more or less 120%) better at texture filtering than the GeForce GTX 980. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce GTX 980		144128 Mtexels/sec
	Difference: 172672 (120%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 2080 SUPER is the winner, by far. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
GeForce GTX 980		72064 Mpixels/sec
	Difference: 33536 (47%)

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 maximum amount of information (counted in MB per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
