The stock image was running Kernel 6.1, which predates your LKML post, so would depend if it was backported.

I want to have a play with UEFI support and get mainline booting when I get a chance.

Not sure if any acceleration was in use. 50% perf hit for encryption is a bit more than I expected TBH.

In general the IO throughput seemed better than I expected. Easily beats an RPI CM4 with an SSD.

Was testing pretty quickly, might play a bit more if I get some time in the week.

I did some benchmarking of the Rock 5B, stock install of the provided OS. Power stats taken directly from lab bench PSU. Power looks to easily be under 20W for most applications.

Rock 5B (16GB) with Crucial P3 512GB SSD, running Linux rock-5b 6.1.43-14-rk2312.

Power:
Idle: 5V @ 0.66A
All CPU stress: 5V @ 1.39A
Single CPU Stress: 5V @ 0.81A
7Zip Bench: 5V @ 2.18A
CPU Stress + IO RW: 5V @ 1.69A
IO 1 Job RW: 5V @ 1.32A
IO 1 Job W: 5V @ 1.71A
Multi-job IO: 5V @ 1.71A - 2A

@yawnbox I suspect for your usecases it would be <= 20W.

It's probably being cautious on what peripherals people attach.

AFAIK it's the same CPU as the Orange PI Max.

I can measure the power consumption of mine over the weekend, if you want?

Yes, I would agree pay is also behind where is needs to be. Especially the gulf between UK and US pay for the industry.
