Roughly 40% of their revenue is consumer chips where, apart from some games optimisation, they are no longer standing out from the crowd, and the leader is arguably Apple, with AMD doing well. The next ~30% of their business is servers, where there may be a significant number of HPC clients, but the bulk of this is again likely to be VMs running non-Intel specific software, and this market is starting to realise that Intel is nothing special here.
Looking at their revenue breakdown, I struggle to put more than 20% into the things that you mention they are great at. Should they focus on this? It would lose them much of their market cap if they did.
