Going back what Apple stated about A14 being 40% faster than A12, A14 should be about 16% faster than A13. Add 16% to the A13 scores and it easily beats those Tiger Lake numbers in SPEC2006, for both int and fp.

That doesn't even include the bigger caches and wider memory that the A14X will get, nevermind if they have something even better than A14X in store for that Macs arriving later this year.
