GeForce GTX 1080 vs GeForce RTX 2060 Super

Intro

Compare all that to the GeForce RTX 2060 Super, which has core clock speeds of 1470 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 RAM. It features 2176 SPUs along with 136 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2060 Super		175 Watts
GeForce GTX 1080		180 Watts
	Difference: 5 Watts (3%)

Memory Bandwidth

Theoretically, the GeForce RTX 2060 Super should be quite a bit faster than the GeForce GTX 1080 overall. (explain)

GeForce RTX 2060 Super		458752 MB/sec
GeForce GTX 1080		327680 MB/sec
	Difference: 131072 (40%)

Texel Rate

The GeForce GTX 1080 will be a lot (more or less 29%) better at texture filtering than the GeForce RTX 2060 Super. (explain)

GeForce GTX 1080		257120 Mtexels/sec
GeForce RTX 2060 Super		199920 Mtexels/sec
	Difference: 57200 (29%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 1080 is a better choice, but it probably won't make a huge difference. (explain)

GeForce GTX 1080		102848 Mpixels/sec
GeForce RTX 2060 Super		94080 Mpixels/sec
	Difference: 8768 (9%)

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 max amount of data (in units of MB per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units 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 applied in one second.

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