GeForce RTX 2080 SUPER vs Geforce GTX 1080 Ti

Intro

Compare those specifications to the Geforce GTX 1080 Ti, which comes with GPU core speed of 1480 MHz, and 11264 MB of GDDR5X RAM set to run at 1376 MHz through a 352-bit bus. It also is comprised of 3584 Stream Processors, 224 Texture Address Units, and 88 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The GeForce RTX 2080 SUPER, in theory, should perform a bit faster than the Geforce GTX 1080 Ti in general. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
Geforce GTX 1080 Ti		495616 MB/sec
	Difference: 12288 (2%)

Texel Rate

The Geforce GTX 1080 Ti should be a little bit (more or less 5%) more effective at AF than the GeForce RTX 2080 SUPER. (explain)

Geforce GTX 1080 Ti		331520 Mtexels/sec
GeForce RTX 2080 SUPER		316800 Mtexels/sec
	Difference: 14720 (5%)

Pixel Rate

The Geforce GTX 1080 Ti is quite a bit (approximately 23%) faster with regards to FSAA than the GeForce RTX 2080 SUPER, and capable of handling higher resolutions better. (explain)

Geforce GTX 1080 Ti		130240 Mpixels/sec
GeForce RTX 2080 SUPER		105600 Mpixels/sec
	Difference: 24640 (23%)

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 max amount of information (counted in megabytes per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

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