GeForce RTX 2060 Super vs GeForce RTX 2080 SUPER

Intro

Compare those specs to the GeForce RTX 2080 SUPER, which comes with a GPU core clock speed of 1650 MHz, and 8192 MB of GDDR6 memory running at 1937 MHz through a 256-bit bus. It also features 3072 SPUs, 192 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2060 Super		175 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 75 Watts (43%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2080 SUPER should perform a bit faster than the GeForce RTX 2060 Super overall. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
GeForce RTX 2060 Super		458752 MB/sec
	Difference: 49152 (11%)

Texel Rate

The GeForce RTX 2080 SUPER should be a lot (approximately 58%) more effective at AF than the GeForce RTX 2060 Super. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce RTX 2060 Super		199920 Mtexels/sec
	Difference: 116880 (58%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 2080 SUPER is superior to the GeForce RTX 2060 Super, though only just barely. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
GeForce RTX 2060 Super		94080 Mpixels/sec
	Difference: 11520 (12%)

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 (measured in MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics 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 could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
