I don't think Intel will launch their 10nm chips.
If Zen 2 is 7nm DUV (also known as N7, the same AMD used for Radeon VII), I doubt Intel really needs 10nm to compete.
They can keep polishing 14nm and focus on their 7nm - to compete with Zen 3 based on TSMC 7nm EUV (N6?) coming next year at best.
This came as no surprise, as ALL 14 nm APU's (2200G, 2400G, 2700U...) should've been part of the 1000 series. (Yes, I know they're different from the Summit Ridge 1000)
Basically, what AMD is trying to tell us is that the xxxx CPU's and the xxxxG/U APU's are not in the same series, they just happen to begin with the same number.
But most marketing materials and AGESA leaks mention Ryzen 3000-series, not Zen 2 or 7nm.
People interpret this as Zen 2, but there's no actual guarantee. X370 motherboards (after update) may as well be compatible just with Ryzen 3000-series based on Zen+ (be it APU or not).
DUV vs EUV does not necessarily have an effect on performance of the resulting chip. The difference is complexity of design and production as well as the time it takes to produce the chips. All this translates to (a lot of) money.
Correct. Which means Zen 2 is sure to be expensive*, while it's unknown at this point how much performance/efficiency gain we could get**.
It does seem like Zen 2 will be very short-lived. Basically, they're launching this only because Intel caught up on core count.
And if Zen 2 turns out to be the last generation for AM4, then the "great upgrade path" will suddenly look a lot less great.
*) so why make <=8C Zen2 at all? Why not refresh Zen+ for this segment and save Zen2 for 12-core and up? These refreshed Zen+ 3000-series would surely work on X370...
