In benchmarks, sure. In real world usage, probably not. While some people will utilize higher end processors, a vast majority of them will not. If you're not doing something like encoding video, there is a good chance you won't notice a difference. CPUs are well beyond what is needed for typical office tasks today. A 10 year old laptop can be upgraded with an SSD and 8GB of RAM and work just as well for an average person versus a quad core laptop with an SSD and 8GB of RAM from today.
I can run 5+ Linux VMs on my m5 from 2015. On my old 15" rMBP I could run a hell of a lot more. But for my typical workload, 5 is plenty for my automation tests. So even though I run a lot of VMs, I don't see a benefit for the 15" over the 12" today.
