The oPi5 hardware is much better than the rPi5. The oPi5 has 4 extra 
efficiency cores, the oPi5 RK3588 is 8nm, the rPi5 Broadcom BCM2712 is 
16nm. The oPi5 comes with a NVMe socket.

In practice the oPi5 seems faster, and uses about half the power, it 
will run off a normal(ish) USB power plug.

The problem is the OS (I use Armbian) isn't quite as good a rPi5. 
Although the oPi5 is getting better and has open source GPU drivers.

For a GUI/Desktop the rPi5 is still a little buggy compared to Intel/AMD 
Linux. While the rPi/Pi OS is good for a server, I wouldn't recommend 
either it, or the oPi5, as a desktop, unless you like tinkering.

My perception is that the Aarch64 SoC Linux software is improving. Maybe 
the next round of devices will truly be mass market desktops.

Yeah, that is the proper name. I see they do provide a service to force 
a reboot. Which I guess is what I wanted.
