The RAM part numbers on the A8 start with H9CKNNN... which is Hynix LPDDR3. So no LPDDR4. The A7 die they show begin with the same numbers. The next digit after the N determines the capacity with 8 being 1 GB (ie. H9CKNNN8) and B being 2 GB (H9CKNNNB). Sadly the image isn't high enough to make it out.
