IBM chooses Samsung for POWER10

It's official: Samsung will manufacture the upcoming POWER10 on their 7nm EUV process thanks to an expansion of IBM and Samsung's 15-year R&D partnership. The next z microprocessors, which have some low-level microarchitectural similarities to the Power line, will also be produced on 7nm EUV. There are still relatively few details available about either CPU; POWER10 is still scheduled for around 2020-1.

This doesn't change plans for the upcoming final revision of POWER9 in 2019. More details should be forthcoming as that release date approaches.
