Factor in power usage, thermals (esp if they're sharing a living space with you), and time. This is where the modern CPUs on 2nm process nodes really start to pull ahead, especially when you can S3 sleep them or use IPMI type BMCs on stuff like real workstation-class systems and servers. Even an M6 Mac Mini can do a ton of work these days, and single-core speeds on those especially when you look at perf/watt are insane.
