While the switch from 14nm to 10nm took Intel extremely long due to significant issues with the process technology, the company is confident that it will be offer its 7nm on track. Tom's Hardware writer Arne Verheyde sums up some recent remarks from Intel via his Twitter feed.
At a recent investor talk, Intel's cloud VP hinted that 7nm Xe will be Intel's first GPU for the datacenter market. This implies the 10nm lineup that will launch in 2020 will be for the gaming market.
Intel's Ice Lake-SP got delayed from June 2020 to "the second half of the year", the chip giant says this has nothing to do with 10nm yields or output. The problem is developed validation, as Intel has two 10nm server products planned for 2020. Coooper Lake in Q1 2020, and Ice Lake in the second half.
The weekly yield curves seen on 10nm are reportedly "ahead of schedule", which is presumably the heavily revised schedule (after many years of delays).
Speaking about 7nm, Intel is feeling very good about 7nm. The future process allegedly scores good in terms of power and performance. The plan is to do a two year cadance from 10nm to 7nm, which means a 2021 launch of 7nm processors.
