GeForce RTX 2070 Super vs GeForce RTX 2080

Intro

Compare all that to the GeForce RTX 2080, which has GPU core speed of 1515 MHz, and 8192 MB of GDDR6 memory set to run at 1750 MHz through a 256-bit bus. It also features 2944 Stream Processors, 184 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

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

Texel Rate

The GeForce RTX 2080 should be a small bit (approximately 9%) better at texture filtering than the GeForce RTX 2070 Super. (explain)

GeForce RTX 2080		278760 Mtexels/sec
GeForce RTX 2070 Super		256800 Mtexels/sec
	Difference: 21960 (9%)

Pixel Rate

The GeForce RTX 2070 Super will be a little bit (approximately 6%) faster with regards to anti-aliasing than the GeForce RTX 2080, and also will be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce RTX 2070 Super		102720 Mpixels/sec
GeForce RTX 2080		96960 Mpixels/sec
	Difference: 5760 (6%)

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 data (counted in MB per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 can be processed in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip 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 colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
