NicoD Posted July 11, 2019 Posted July 11, 2019 Hi all. I've just finished reviewing the Khadas VIM3. It's an amazing SBC with unmatched performance. It's got the Amlogic A311D SoC. Comparable with the S922X of the Odroid N2. But the 4x A73 cores are clocked at 2.2Ghz and the 2 x A53 cores to 1.8Ghz. So it performs a lot better. It also comes with an NPU, MIPI-DSI and MIPI-CSI. And can be powered with USB type-c from 5V up to 20V. Here my review video. Here all my gathered information. Khadas VIM3 ----------- Ubuntu server - fan over fins ----------------------------- Blender BMW no fan thermal pad : 59m with copper shim : 58m18s 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 Blender with fan : 46m29s Armbian Disco Small cores @1.9Ghz Big cores @1.7Ghz Blender with fan : 46m56s Armbian Buster 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 Greetings, NicoD 1

NicoD Posted July 11, 2019 Author Posted July 11, 2019 @lanefu Sorry, I forgot to share my benchmark file. I did find out that 7-zip multicore results are not to be trusted on SBC's with different cluster performance. The VIM3 has a very big difference so it only uses 500% of 600%. The N2 has a smaller difference in performance between A73/A53 so uses 550% in 7-zip multicore scores. (also lack of memory is a problem) CPU Miner is good, 7zip single core benchmarks are good. And for me Blender is important too. Reasons why benchmarks can be misleading ---------------------------------------- throttling 32-bit/64-bit Difference in cores A53/A7/A15/A72 distro (ubuntu/debian...) distro version kernel version driver versions compiler version software version/outdated repositories desktop Mate/Xfce/LXDE/... display resolution/headless background processes cpu clockspeed ram clockspeed/latency ram useage/swap/zram process sheduler optimizations for the system/distro crypto engine for encryption Undervoltage config settings Wifi dongle CONFIG_HZ=250 - 1000 or any other 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. 64-bit SBC's Khadas VIM3 |SBC bench result

Richard.Kang Posted September 12, 2019 Posted September 12, 2019 Any luck of installing TensorFlow on the board? I need it for my project so it will be a deal breaker if I can't get TF installed and running on it. Thanks! Richard 1
