GeForce GTX 1070 262144 MB/sec
Difference: 196608 (75%)

Texel Rate

The GeForce RTX 2080 is a lot (more or less 54%) faster with regards to anisotropic filtering than the GeForce GTX 1070. (explain)

GeForce RTX 2080 278760 Mtexels/sec
GeForce GTX 1070 180720 Mtexels/sec
Difference: 98040 (54%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce RTX 2080 is superior to the GeForce GTX 1070, not by a very large margin though. (explain)

Memory Bandwidth: Bandwidth is the max amount of information (measured in MB per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the 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 number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
