Those 2015 processors were some damn good processors though - at that point they were quite far ahead. I haven't counted Intel out of the game just yet like many here seem to - they have definitely hit a stumble though for sure.
It's a risky bet to say intel is going to recover imho. A lot of good engineering talents have left intel. I dunno if they are capable of rehiring back those people. I suppose the new CEO is going to help.
Not many companies recover like this. Microsoft is one notable exception - and they recovered because they have a huge cash cow, and that gives them a tonne of runway.
The 12000 series has already bought intel a lot of breathing room. It's outperforming AMD on gaming workloads at a lower price point, AMD have recognized this and lowered their prices.
AMD also recovered because they couldn't be killed, as Intel was never going to be allowed becoming a single source for x86. I.e. the US military said: We need more than one company doing the processors we need. Not sure if the same is true for Intel today. There are multiple providers for sufficiently powerful processors and from an enduser perspective the actual architecture doesn't matter much. I.e. it's far simpler to repurpose any other source today than it was 20 years ago.
Nokia also recovered, not only they own UNIX birthplace, the Android phones using their branding are actually the few Android ones that get proper updates.
However hiring Elop, with the contract bonus clause to sell Nokia Mobile, was a really dumb move.
