Hi all.
I’ve finished my review of the Khadas VIM3.
It is an amazing SBC with unseen performance and amazingly power efficiency for this performance.
Here is my video:
In the 2nd post I’ll share all my gathered data.

Hi all.
I’ve finished my review of the Khadas VIM3.
It is an amazing SBC with unseen performance and amazingly power efficiency for this performance.
Here is my video:
Khadas VIM3
-----------
Ubuntu server - fan over fins
-----------------------------
Blender BMW no fan thermal pad : 59m

with 5V fan : 45m01s
with 5V fan over CPU : 43m28s
Ubuntu XFCE - fan over CPU, not over fins
-----------------------------------------
Blender no fan : 55m22s
Blender 3V fan : 43m03s
Blender 5V fan : 42m51s
Blender with fan : 48m45s Armbian Bionic Small cores @1.9Ghz Big cores @1.7Ghz

Kdenlive 16m bench 3V lxde : 1h09m (using 1GB zram + 4GB swap file. Not enough ram with 2GB)
Video playback
--------------
Ubuntu
------
Up to 4K 30fps with MPV. Very slight screen tearing. Anything lower is perfect
Youtube playback with Firefox up to 1440p 30fps perfect
KODI doesn't work (yet)
No VPU acceleration for now. All done by CPU.
LibreElec
---------
Up to 4K 30fps with MPV. Very slight screen tearing. Anything lower is perfect
Wifi doesn't work.
power consumption
-----------------
Idle no fan : 0.27A 5V (governor set to interactive)
Maxed out with fan : 1.4A 5V (fan is 0.15A)
Temperatures (fan over CPU, not over fins)
------------------------------------------
Idle No fan : 44°C
Maxed out No fan : 75°C heavy throttling. 1Ghz small cores / 1.8Ghz big cores
Idle 3V fan : 34°C
Maxed out 3V fan : 73°C very light throttle. Takes 5min to reach 70°c. +10min to start throttling
Idle 5V fan : 32°C
Maxed 5V : 70°C no throttling
Transfer speeds
---------------
eMMC 16GB : 60 MB/s write
: 165.9 MB/s read
SSD over USB3 : 380.3 MB/s write
: 286.1 MB/s read
SSD over USB2 : 40.2 MB/s
Samsung EVO plus with on-board sd-reader : 10.2MB/s write 22.1MB/s read
with USB3 sd-reader : 31.7MB/s write 88.6MB/s read
Ethernet internet speed : 53.9 Mbps 11.5 Mbps
Wifi internet speed : 43.7 Mbps 11.2 Mbps
Issue's
-------
When using a 2.4Ghz dongle for mouse in the right USB3 port, wifi connection is slow.
When using a USB3 device in the USB3 port wifi stops working. Use left USB2 port for those.
Ubuntu server boots/shuts down slower than XFCE version. Shut down stop job for ifup for eth0 (not in use) 1m30s
Boot hangs a while. Can't find the reason. After -> Scanning for Btrfs filesystems. Done. about 30s
Can't install Tensorflow
khadas@Khadas:~/tensorflow$ pip3 install tensorflow-1.8.0-cp35-none-linux_aarch64.whl
tensorflow-1.8.0-cp35-none-linux_aarch64.whl is not a supported wheel on this platform.
Android : Can't connect wifi. I can type wifi password, but can't go further. No connect button.
Tips
----
Use interactive governor for better thermals and power consumption with low use/idle.
Plus/Minus
----------
+ Best single core performance + best multi-core performance for an ARM SBC
+ Nice case + PSU + USB-c cable included + remote + eMMC
+ Amazing low power consumption / best performance per watt
+ Can be powered with 5V up to 20V
+ NPU
- Wifi issue with USB3/No 5Ghz wifi. Could have solved the USB3 interference
- Placing of the buttons would be better on the back. They often get pressed when plugging a USB device. You do get used to it.
- No VPU and X11 drivers (yet)
- Slow On-board SD-card reader
Here the benchmark results.

7-zip works a bit better on 32-bit vs 64-bit, it doesn't use all cores at 100% in multi-core scores. The percentage differs with different distro's and boards. So it's not completely exact.
7-zip has problems with big-LITTLE architecture for multi-core benchmark. Better to test the clusters seperately.
Blender works a lot better on 64-bit than on 32-bit. It uses 100% of the cores.
CPU Miner only works on 64-bit. Works better in Ubuntu Bionic than in Debian Stretch.
Blender : BMW render @ 1080p
7-zip : Numbers are average of 3 of decompressing only
All tests are done with a fan when necessary so no throttling occurs.

Some benchmark tools can give an estimate of the performance. But they are never an exact reflection.
You start in Libreelec plaer MPV ???
In Ubuntu I need to use MPV for that, and with LE it also works to watch video(not with MPV).
I’ll make a video about LE seperately. People ask about a tutorial video for it.
Also about your Armbians I will make a seperate video to compare the performance of buster vs stretch, and bionic vs disco. Cheers
Thank you very much for what you did.
Great testing and sharing.
The thermal throttling and WiFi/USB3 issues makes upsets.
This should be resolved in the future.
There is no heat problem on the VIM3. The standard radiator provides 80% of the modes of use of all users without the use of a fan. This is the correct calculation. If you plan to use with a load factor of 100%, only the active cooling system (fan) can guarantee the correct operation of the system in all modes (at any ambient temeparutre). This applies to all models of this class on the market. The cost of a passive cooling system for a load of 100% is many times higher than the cost of an active cooling system. The passive system for 100% of the load is used only in special cases where the costs do not matter and there is a strict requirement to use only passive systems.
Have you tried the latest version Armbian with kernel 5.2.1 which enabled all cores at maximum frequency for a311d ?
Thanks for thermal clarifying and it makes confidence for VM3
Pls keep chasing and evaluating the WIFI/USB and SD performance issue.
Hope the new VM3 V12 will be rock-solid in hand soon.
It seems that many CE users(N2 funs ) have not got your info.
With minimal HW support, All *elec give a miniscule load for which a piece of iron on N2 has no benefit. For reference, Libreelec works fine on VIM3 without any radiator at all. I have a regular radiator when working LE temperature does not exceed 40-45 degrees at maximum resolution.
PS I know who he was.
Yes I have. Already done a few benchmarks Great job.
The base clock of the big cores is 2.11Ghz, but 2.21Ghz is available. Also no thermals what could make it a bit dangerous since it’s not throttling.
I’ll try to make my video about it next week. Too much work now, thanks.
