I don't know what you consider "actually new" hardware. The machine I use to work has 16 Gb of RAM. Ryzen 7 and an AMD GPU. For me that's a pretty decent and recent hardware.
If you meant the lastest of the latest GPU, processor, chipset and so you you might better off with Linux.
But the fact that the computer that was given to me was boxed from factory and bought after two weeks after started is a sign of recent hardware. I haven't tried it but two other person where I work have high end brand new ThinkPads and I'm confident FreeBSD can be run on those well too.
If Zen3+ vs Zen3 is a significant architectural difference, than it would slightly miss the 5 year mark, since it was released 4.5 years ago.
