GeForce RTX 2070 Super vs GeForce RTX 2080

Intro

Compare all that to the GeForce RTX 2080, which uses a 12 nm design. nVidia has clocked the core frequency at 1515 MHz. The GDDR6 memory is set to run at a speed of 1750 MHz on this specific card. It features 2944 SPUs as well as 184 TAUs 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 in theory they should have the same performance. (explain)

Texel Rate

The GeForce RTX 2080 will be just a bit (approximately 9%) more effective 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

If using high levels of AA is important to you, then the GeForce RTX 2070 Super is a better choice, though not by far. (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 largest amount of data (in units of megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If 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 higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
