Yeah, that's the problem though, in order to be ready for a failed 7 nm rollout in 2023, you need to be planning now. From the whispers I've heard, Intel's ego is preventing them from making a plan B (meaning 3rd party fabs) right now. If 7 nm does face additional delays, trying to make a plan B even this time next year will be too late and push Intel that much further behind. From what I understand, Intel's plan B is essentially 10+++, which IMO, would be disastrous for Intel. This is just what I've heard through the grapevine so take with as much salt as you'd like.If they can actually get CPUs based on 7nm by late 2022/early 2023, it is probably going to be fine, but if they can't, this is probably the time they should be preparing plan B (using TSMC 5nm or Samsung 5/3nm). Not having competitive product out there is more devastating than worrying about wasting previous investment.
