The listing reveals little about the processor part of this APU but shows quite a bit of information about the integrated graphics. Referred to as AMD 15FF Graphics, this is an integrated graphics solution that features 28 compute units (CUs), 1792 shader processors and 2GB of memory.
Lots of unknowns here but presumably the integrated graphics part is based on Vega. That implies this will be a very potent APU as it has half the CUs of the Radeon RX Vega 56. The memory type is unknown, it could be HBM2. The processor part should be Zen-based and it's clocked at 2.4GHz. This is probably planned for 2018 and that implies the thing may be fabbed on the same GlobalFoundries 12nm node as AMD's upcoming Ryzen 2000 series.
