Technology: 28 nm and 14 nm. 7 nm planned. However, in August 2018, GlobalFoundries made the decision to suspend 7 nm development and planned production, citing the unaffordable costs to outfit Fab 8 for 7 nm production. GlobalFoundries held open the possibility of resuming 7 nm operations in the future if additional resources could be secured.

So, not a state of the art fab. Couldn't afford to keep up.
