GeForce RTX 2060 Super vs GeForce RTX 2080

Intro

Compare those specifications to the GeForce RTX 2080, which comes with core speeds of 1515 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 RAM. It features 2944 SPUs as well as 184 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2060 Super		175 Watts
GeForce RTX 2080		215 Watts
	Difference: 40 Watts (23%)

Memory Bandwidth

Both cards have the exact same memory bandwidth, so theoretically they should perform the same. (explain)

Texel Rate

The GeForce RTX 2080 is a lot (approximately 39%) more effective at texture filtering than the GeForce RTX 2060 Super. (explain)

GeForce RTX 2080		278760 Mtexels/sec
GeForce RTX 2060 Super		199920 Mtexels/sec
	Difference: 78840 (39%)

Pixel Rate

The GeForce RTX 2080 will be a small bit (more or less 3%) more effective at full screen anti-aliasing than the GeForce RTX 2060 Super, and capable of handling higher resolutions more effectively. (explain)

GeForce RTX 2080		96960 Mpixels/sec
GeForce RTX 2060 Super		94080 Mpixels/sec
	Difference: 2880 (3%)

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

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

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