GeForce RTX 2060 Super vs GeForce RTX 2080

Intro

Compare all that to the GeForce RTX 2080, which has a core clock speed of 1515 MHz and a GDDR6 memory frequency of 1750 MHz. It also uses a 256-bit bus, and makes use of a 12 nm design. It features 2944 SPUs, 184 TAUs, 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 exactly the same memory bandwidth, so in theory they should have the same performance. (explain)

Texel Rate

The GeForce RTX 2080 should be a lot (approximately 39%) better at AF 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

If running with high levels of AA is important to you, then the GeForce RTX 2080 is a better choice, but it probably won't make a huge difference. (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: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling 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 chip can possibly record to the 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 the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
