GeForce GTX 970		224000 MB/sec
	Difference: 38144 (17%)

Texel Rate

The GeForce GTX 1070 Ti should be a lot (more or less 124%) more effective at texture filtering than the GeForce GTX 970. (explain)

GeForce GTX 1070 Ti		244264 Mtexels/sec
GeForce GTX 970		109200 Mtexels/sec
	Difference: 135064 (124%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 1070 Ti is a better choice, and very much so. (explain)

GeForce GTX 1070 Ti		102848 Mpixels/sec
GeForce GTX 970		67200 Mpixels/sec
	Difference: 35648 (53%)

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 max amount of data (counted in MB per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the graphics 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 amount of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of 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 fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
