Was Intel Holding Back?

I just noticed that Intel had its arch day today.


I remember that for years when Broadwell was introduced we had lengthy arguments over that theoretical x86 IPC wall. Some attributed Intel's lackluster IPC improvements to a theoretical IPC wall of the x86 ISA. Others simply argued that Intel was holding back due to lack of sufficient competition. Now that know Golden Cove does another 1.2x IPC, it brings the number to 1.45x IPC improvement over Skylake in single thread integer workload. Given that's more/about what Intel did from Sandy Bridge to Skylake, it sure feels like they were simply holding back?
