It will be interesting to see if it gets A13X (early 2020) or A14X (late 2020). Traditionally, the X chips are roughly 60% faster than the non-X chips.
We already know A13 performance. Extrapolating, that would make A13X roughly 20% faster than A12X.
OTOH, a rough guess might be that a hypothetical A14X would be approximately 45% faster than A12X.
Not that I really care, as I'm more interested in other factors. A12X is already very, very fast. I suspect they could improve the hardware HEVC encoder though for the video junkies, for example.
