They are limited to 4 cores. In the new lineup too, when G series comes out later, they'll be limited to 8 cores (one cliplet for CPU and one for GPU).
For the vast majority of professional use cases 8 core / 16 thread running at 4.5+ boost is going to be way enough for a while. AMD sure has spoiled the market in just two years on commoditizing 8 core desktop chips because in 2016 the conversation would be about what flavor of $400+ quadcore or $800+ sextacore from Intel you were going to get.
