Yesterday some shipping info popped up on the web, indicating that nvidia is moving around what seems to be Pascal., Pascal is the next-generation Nvidia flagship graphics processor tagged under codename GP100.
It seems that a batch of completed chips have been sent from TSMC towards NVIDIA for testing and evaluation.
It is rumored that the flagship GPU will get 17 billion transistors made on the 16 nm FinFET+ node at TSMC. The GPU will get HBM2 memory with allowance up-to 32 GB of memory (very unlikely, more like 8 or 16 GB).
Anyway, aside from the tracking info below, take this news from 3dcenter with a huge grain of salt please.
