Even semiaccurate rehashes their own articles, I've seen those points made before.
https://semiaccurate.com/...-intels-10nm-problems/Even if those talking points of Intel were accurate (no pun intended), it's old news, I doubt those attitudes are still there now. 10nm is late, so much that Skylake is being refreshed twice as Kaby and Coffee.
The only reason Coffee is coming, if you think about it, is that there is no room in nomenclature series to put a 6-core into mainstream if 7700K and 7740K is top end quad, because 7800 is in HEDT. It would have introduced a confusing overlap, so they introduce a new number sequence with it's own codename and gives them the opportunity to sell another chipset.
Cannon should have been the 7-series after 6-series Sky, per early Client Group roadmaps with no delays. Add my theory that Intel would have wanted to consolidate all unlocked to one platform while locking out Client, 6700K should have been the last unlocked SKU for the Z-chipset, if they didn't retire Z for just the H-series while putting all unlocked quads on up into X299. They could all been called Core i7 if AMD never came back.
Furthermore and getting back to topic, the next lean x86 architecture is also delayed (possibly due to starting late, i.e. right after AMD revealed Zen in May 2015), which is why Cannonlake has a pair of refreshes at 10nm called Ice and Tiger-- I'm not dumb, those are both still lake architectures. It's after Tiger we see something new, which I why I recommend no one upgrade to any Lake processor unless you already have one. It'll be worth the wait, it's going to be like Core 2 again.
How do I know? Intel needs a wide berth from Zen and all iterations to allow the refresh cycle to start again, that's what Core (80% over Netburst), Nehalem (25% over Core) and Sandy Bridge (17% over Nehalem) gave Intel against AMD last time. AMD took 5 years to come back, Intel wants that again. This time they will try for an extreme boost like well over 50% IPC off of Skylake, I'm thinking 70%. It will allow running lower frequencies and better binning with lower power, and still be better than last gen.
I'd like to think AMD isn't sitting on their hands, even they said Zen would last four years, that gives Intel at least 1-2 years of dominance with their new arch; after that they better have something, but without Jim Keller, I don't know. I figure Intel is betting a Bulldozer 2.0 will come after Zen in order to have their refresh rebrand cycle throughout the 2020's.
