GeForce GTX 1070 Ti vs GeForce RTX 2080

Intro

The GeForce GTX 1070 Ti makes use of a 16 nm design. nVidia has set the core frequency at 1607 MHz. The GDDR5 memory works at a frequency of 2000 MHz on this card. It features 2432 SPUs along with 152 TAUs and 64 Rasterization Operator Units.

Compare that to the GeForce RTX 2080, which features a core clock frequency of 1515 MHz and a GDDR6 memory frequency of 14 MHz. It also features a 256-bit memory bus, and makes use of a 12 nm design. It is made up of 2944 SPUs, 184 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1070 Ti 180 Watts
GeForce RTX 2080 215 Watts
Difference: 35 Watts (19%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2080 should be 75% faster than the GeForce GTX 1070 Ti in general, because of its greater data rate. (explain)

GeForce RTX 2080 458752 MB/sec
GeForce GTX 1070 Ti 262144 MB/sec
Difference: 196608 (75%)

Texel Rate

The GeForce RTX 2080 will be a bit (more or less 14%) more effective at AF than the GeForce GTX 1070 Ti. (explain)

GeForce RTX 2080 278760 Mtexels/sec
GeForce GTX 1070 Ti 244264 Mtexels/sec
Difference: 34496 (14%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 1070 Ti is superior to the GeForce RTX 2080, but not by far. (explain)

GeForce GTX 1070 Ti 102848 Mpixels/sec
GeForce RTX 2080 96960 Mpixels/sec
Difference: 5888 (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.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units of the card by the core clock 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 applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. 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 rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
