The way I see it, the death knell will come for Intel in the form of more PC OEMs shifting to integrated processor chips for the performance benefits, leaving less of a market for standalone processor / graphics card businesses like Intel, AMD and Nvidia. It’s not that people will suddenly abandon their Intel PCs for M1 Macs in droves. It’s that Apple will create a new parallel market that the PC manufacturers will eventually hop on, leaving Intel’s legacy business model behind.
For all we know, building your own PC may eventually be relegated to an enthusiast market as well.
One can dream…
