The render appears to confirm it is a dual die design with as many as 8 HBM stacks. According to rumors, the GPU is to feature up to 110 Compute Units and 128 GB of HBM2e memory.
What might be interesting to note is that the packaging of dual-die Aldebaran GPU is nearly identical to TSMC CoWoS-3 (Chip on Wafer on Substrate):
