alt Hacker News> a Ryzen 5800h mini PC last year, which roughly lands in the same performance bracket [as a Mac mini].
Not really. And this is before the M5 Mac mini which ships later this year.
Putting it together in desktop‑mini form factors:
- Raw CPU: M4 is much faster single‑core, generally faster multi‑core at lower power.
- GPU: M4’s iGPU is roughly 2×+ Vega 8 and more modern.
- Memory subsystem: M4 has far higher bandwidth and unified memory, ideal for integrated GPU and many modern workloads.
- Efficiency/noise: M4 wins by a large margin; much higher perf per watt.
- Compatibility: 5800H wins if you need bare‑metal x86 OSes like FreeBSD or specific x86‑only software stacks.
- 5800H: 35–54 W configurable TDP in laptops; mini‑PC implementations often run it fairly hot to maintain clocks.
- M4 in Mac mini: ~24 W base TDP, ~40 W boost, but getting clearly higher performance per watt.

The M4 is from 2024, the 5800h is from 2021. You should be comparing against the M1 or M2, which was Apple's actual competitor at that performance bracket and time period.
Let's assume the 5800H consumed 50W and the mini consumed 0W and both ran 100% utilization all year at $0.20/kWh.
The mini would save $87/year. That's a 3.5y breakeven assuming no reinvestment.
