sha3 is a lot more power efficient when implemented in hardware, which is nice when you have an IoT device that needs to do a lot of hashing. It will also be really nice on amd_64 CPUs for doing large amounts of hashing if they ever get a sha3 instruction. That said, hashing is rarely your bottleneck so there's not much urgency.
