Arachnotronic a simple question. Intel has been moving to a new process node with < 100 sq mm dies and 5w-15w chips at 14nm and 10nm. Next year we will have 14nm++ and 10nm coexisting. I see a similar situation with 10nm++ and 7nm . So when Intel say that DCG will move first to 10nm++ and 7nm first what do they mean ? How can something be manufactured at 2 nodes which will pretty much overlap in time ?
Here is my understanding/guesses, this is not official info, so it comes with no guarantee what-so-ever that it's right
Late 2017-early 2018: Cannon Lake-Y on 10nm, everything else on 14nm++ (Coffee Lake-U/S/H, Kaby Lake Refresh U).
Late 2018: Begin manufacturing Ice Lake-Y/S/H/U on 10nm+. I would expect some Ice Lake product in the market during 2H 2018, but with the full launch like we saw with Kaby in very early 2019 (hopefully I'm wrong and we get the entire stack in late 2018).
Late 2019: Begin manufacturing Tiger Lake on 10nm++ -- the "third wave" of 10nm -- for client machines. Again, I expect some products in market in late 2019, with wider SKU availability in early 2020.
If Tiger Lake client trickles into market in late 2019, with bigger volume in early 2020, then I would imagine that you'll see Ice Lake-EP/EX in the market perhaps in mid-2019. Then, we'll see the first 7nm server family, Sapphire Rapid, in mid-2020.
