Benchmark results

CPU

Power

Methodology: Since I don't have a Jetson carrier board I can use with a single SoM slot for the RK1, I am going to boot the Turing Pi 2 board with no modules installed, wait 5 minutes, and get a power reading. Then I will insert a node in slot 1, and get a power reading, then add another in slot 2, and get a reading. I should be able to see how the power consumption changes in those scenarios, and hopefully just be able to subtract the Turing Pi 2 board-alone-power-consumption. It's not a perfect methodology, but what are you gonna do in this case?

  • This was measured on the SoM-level, not accounting for power supply losses or carrier board power consumption. Including that, at least with the Turing Pi 2, idle power consumption would be around 5W.

The other power metrics were measured board-level, incorporating power supply losses and BMC power draw, totaling around 2W.

Also benchmarking a full cluster of 4x RK1 nodes over on top500-benchmark: https://github.com/geerlingguy/top500-benchmark/issues/27

geerlingguy commented 9 months ago

On one of the nodes, I was trying to update software, and got:

E: Release file for https://ppa.launchpadcontent.net/jjriek/rockchip/ubuntu/dists/jammy/InRelease is not valid yet (invalid for another 16h 59min 14s). Updates for this repository will not be applied.

So I had to manually force a time re-sync:

sudo timedatectl set-ntp off
sudo timedatectl set-ntp on

On my Turing Pi 2 board, I've upgraded the firmware to 2.0.5 (it looked like it errored out when I tried upgrading, but if I restarted the BMC by power cycling, it had updated), and I installed Ubuntu on all four nodes and have the latest updates in place.

Nodes 1, 3, and 4 will use PWM to spin down the fans and adjust the speed for the CPU/SoC temp... but node 2 for some reason always spins the fan full speed.

If I check the fan speeds I see:

ubuntu@turing2:~$ cat /sys/devices/platform/pwm-fan/hwmon/hwmon8/pwm1
100

I've asked on Discord if anyone knows what might be causing the PWM control to not work on a fresh install.

geerlingguy commented 9 months ago

I have the power monitor hooked up now. It looks like in idle state, with no RK1s booted, the board draws 2.6W to power the BMC. Here are some metrics in the default state—with NVMe SSDs on each node:

After shutting down Ubuntu on each node, but leaving the slots powered on, the board consumes 3.7W. After I power off each slot in the Turing Pi BMC, the BMC alone draws 2.6W again. So the slots power rails (with the SoM shut down) consume about 0.25W each.

Next I'll test with no NVMe SSDs plugged in.

Next I'll test performance vs ondemand cpufreq scaling.

Power went from 5.2W to 5.1W. So... not really worth messing with the default IMO for this particular SoM, unless maybe you want to switch to powersave or something for a weird use case.

Confirmed that power consistently jumped to 5.2W with powersave, and down to 5.1W with ondemand.

power monitor

It's worth noting that power consumption depends on settings/software.

For example when running RK3588 devices with mainline (I tried kernel 6.8) then my Rock 5B shows an idle consumption over twice as high and throttling behaviour is nuts too (I'm updating my Rock 5B review soon and will then add a link to actual measurements). As such it would be great if you could add a note about the kernel version you were running (5.10 BSP, 6.1 BSP or 6.x mainline) to consumption numbers :)

geerlingguy commented 9 months ago

@ThomasKaiser - That information is always up in the Linux/system information section :)

I always try to run all tests on the vendor-recommended OS version, and if one doesn't exist (which is thankfully more rare these days), Armbian.

Also, for completeness, the power monitor I'm using is a Thirdreality Zigbee 'smart' plug, I've been setting up a few of these around my test benches for the convenience.

alm7640 commented 8 months ago

Did you ever create a playbook for the RK1 boards?

geerlingguy commented 8 months ago

@alm7640 - See: https://github.com/geerlingguy/pi-cluster — there are a few tweaks needed, and I may do a follow-up live stream with those tweaks added :)

hispanico commented 8 months ago

Did you ever test the NPU on RK1 module?

geerlingguy commented 8 months ago

No, I might test it with Frigate to see if it can perform as well as a Coral on one of my Pi 4/5's.

geerlingguy commented 7 months ago

I've also set up Drupal in a Kubernetes cluster on the RK1 boards, and with real-world performance compared to CM4, some things are a little faster, and some things are a lot faster:

Benchmark DeskPi Super 6C + CM4 Turing Pi 2 + RK1
wrk (anonymous) 78.65 104.30
ab (authenticated) 72.42 165.55

alm7640 commented 7 months ago

Great news on the RK1 Ubuntu fixes for playbook. Plan to test it out asap.
