GeForce GTX 1070 Ti vs GeForce RTX 2080 SUPER

Intro

Compare all that to the GeForce RTX 2080 SUPER, which comes with a core clock speed of 1650 MHz and a GDDR6 memory frequency of 1937 MHz. It also uses a 256-bit bus, and uses a 12 nm design. It is comprised of 3072 SPUs, 192 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1070 Ti		180 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 70 Watts (39%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2080 SUPER is 94% quicker than the GeForce GTX 1070 Ti in general, because of its greater bandwidth. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
GeForce GTX 1070 Ti		262144 MB/sec
	Difference: 245760 (94%)

Texel Rate

The GeForce RTX 2080 SUPER should be a lot (approximately 30%) more effective at AF than the GeForce GTX 1070 Ti. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce GTX 1070 Ti		244264 Mtexels/sec
	Difference: 72536 (30%)

Pixel Rate

The GeForce RTX 2080 SUPER will be a bit (more or less 3%) faster with regards to full screen anti-aliasing than the GeForce GTX 1070 Ti, and should be able to handle higher resolutions without losing too much performance. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
GeForce GTX 1070 Ti		102848 Mpixels/sec
	Difference: 2752 (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 max amount of information (in units of megabytes per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. 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 number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core 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 rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
