Maybe get 4600G? Albeit $54 more dollar, it's a steal for 6C12T with vega7.
Even after above discussion(s), I don't see the need for Heterogeneous cores. Full cores work just fine. In a way we already have special purpose cores for GPUs that makes the system heterogeneous. Again power consumption is really no big deal. Let the consumer buy what he/she wants/needs.
