SK hynix has released a document (PDF) confirming the readiness of its first HBM2 chips for graphics cards. Starting this quarter (Q1 2017) SK hynix will be shipping out the 4GB graphics memory chips as indicated below.
With the above graphics memory chips available AMD should be able to steam ahead and mass produce market ready graphics cards equipped with its Vega10 GPUs. The SK hynix doc says that the HBM2 that ships will offer 1.60Gbps per pin, so that's a bandwidth of 204.8GB/s per stack.
If you have a glance above at the Vega graphics chip, as grasped by Radeon boss Raja Koduri, you will see the lower two segments of the Vega10 multi-chip module (MCM). These are the HBM2 stacks and with two of them equipped the shipping Vega-powered graphics cards will boast 8GB of graphics memory.
