GeForce RTX 2070 Super vs GeForce RTX 2080

Intro

Compare those specs to the GeForce RTX 2080, which features core speeds of 1515 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 memory. It features 2944 SPUs as well as 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 bandwidth, so in theory they should perform exactly the same. (explain)

Texel Rate

The GeForce RTX 2080 will be a small bit (approximately 9%) faster with regards to 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

If running with a high screen resolution is important to you, then the GeForce RTX 2070 Super is superior to the GeForce RTX 2080, not by a very large margin though. (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: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
