GeForce GTX 1080 vs GeForce RTX 2060 Super

Intro

Compare that to the GeForce RTX 2060 Super, which uses a 12 nm design. nVidia has clocked the core frequency at 1470 MHz. The GDDR6 RAM is set to run at a speed of 1750 MHz on this model. It features 2176 SPUs as well as 136 TAUs and 64 Rasterization Operator Units.

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

Performance-wise, the GeForce RTX 2060 Super should theoretically be much better than the GeForce GTX 1080 in general. (explain)

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

Texel Rate

The GeForce GTX 1080 should be quite a bit (more or less 29%) more effective at AF 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 running with a high resolution is important to you, then the GeForce GTX 1080 is the winner, though only just barely. (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: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the 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 texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units by the core 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of 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 potential to get to the maximum fill rate.
