Thanks for reading!
Indeed, AMD will be using TSMC for some 7nm products, but GloFo could still be in the mix. Lisa Su mentioned "different product lines for each", although no word on which products will be going where as of yet. We guessed it may well be GloFo for Zen and TSMC for Navi, but may well be proven wrong.
I'll switch up the story to reflect that - it wouldn't be all that surprising to see TSMC take on the initial 7nm products with GloFo following next year.
