I'd say, a lot would've been fine even if Intel gave them existing 14nm chips, but since all 14nm capacity is gobbled by server chips, it's not gonna happen.
I believe Intel is making a huge error by prioritising big wholesale Xeon buyers like Amazon over OEM manufacturers. Hosting providers will be back the moment Intel regains the tech lead or finally makes 10nm Xeons, but OEMs will walk away and not return.
