I did a benchmark IBD a long time ago. It's about 5% for assumevalid 0. It's massive for certain forms of massive. 😆
The fact that everything else is twice as fast will probably have a decent impact as well.
And it seems they upgraded the power systems quite a bit, which was causing a lot of trouble on Pi 4 with dodgy power supplies.
So, even though it not perfect due to closed binaries, it looks like a really nice upgrade on paper.

On a RockPro64:
```
processor : 5
BogoMIPS : 48.00
Features : fp asimd evtstrm aes pmull sha1 sha2 crc32 cpuid
CPU implementer : 0x41
CPU architecture: 8
CPU variant : 0x0
CPU part : 0xd08
CPU revision : 2
```
Bitcoin core I wrote long ago says:
```

```
Using SATA SSD disks on a real SATA3 connection (not USB) on LUKS (RockPro64 has the encryption extensions) still takes around a week to complete.
