IH is consumer chipset while B is business chipset. Both will be having low end audio like alc892 or 887, same ram speeds+slots but b150 takes lead in mem/dimms per channel and pcie 3.0 vs 2.0 on h110--difference is negligible in real application but it is there. H110 may not support crossfire while b may. You will not be using features offered by B chipset like small business advantage.
Advice will be to buy h110 if pcie 2.0 don't bother you[emoji1]
