NicoD Posted April 6, 2018 Share Posted April 6, 2018 Hello all. I've made a video about the Rock64. I've tried different distro's, but Armbian was the best for me. The only problems I've found was that Synaptic Package Manager didn't work. It crashes when I press the search button. And sometimes surfing was extremely slow. Otherwise it did fix all the problems I've had with the other distro's I've tried. Thank you for all the great work. Now I've started my research with the Orange Pi +2, and again Armbian is the best choice. Greetings, NicoD Here is my video. 4 Link to comment Share on other sites More sharing options...
TonyMac32 Posted April 6, 2018 Share Posted April 6, 2018 A look at some different use-cases is nice, as you can probably tell most of the discussion here is either extrmeely low-level or is for NAS/server capabilities. Link to comment Share on other sites More sharing options...
JMCC Posted April 6, 2018 Share Posted April 6, 2018 I'm guessing that if RPi's were using a 32-bit OS, that could be the cause for the huge performance difference with Rock64 and C2, in addition to RAM speed. Link to comment Share on other sites More sharing options...
JMCC Posted April 6, 2018 Share Posted April 6, 2018 @NicoD And also, I have seen some of your other videos, and you seem to be interested in testing SBC's for desktop usage, which is nice because that is what many of the new SBC users try first when they get their boards. Right now, we are working in several desktop and multimedia related stuff in Armbian, currently with Tinkerboard/MiQi and Odroid XU4. I can let you know when all that stuff is ready, so you can try it and give us some feedback, if you are OK with it. Link to comment Share on other sites More sharing options...

I am certainly willing to test new things. I have got a Tinkerboard and a XU4. Also a C2, Orange Pi plus 2, khadas vim2 max and all the raspberrys. I'll pm you my email adress. Thank you, greetings.

Just compare the 'overclocked' RPi 3 B+ numbers and eg. ODROID-C2 vs. Rock64. Memory throughput numbers here are useful for interpretation: https://libre.computer/2018/03/21/raspberry-pi-3-model-b-review-and-comparison/ (the RK3328 device there has even faster DDR4 memory so this has to be taken into account).

I absolutely agree that DRAM speed is part of the cause, but I don't unserstand why you are discarding armhf vs aarch64 as another important factor.

tkaiser Posted April 9, 2018 Share Posted April 9, 2018 See the numbers for RPi 3 B+: 115 minutes 'overclocked' vs. 136 minutes with stock settings. That's an 18% increase in 'benchmark numbers'. CPU clockspeed raised by 12% and DRAM clockspeed raised by 27.5% with the 'overclocked' settings. Now as an excercise as already mentioned: Rock64 vs. ODROID-C2. Both use Cortex-A53 with 64-bit kernel and userland, the CPU clockspeed difference isn't that much so why does the ODROID-C2 perform that better? Search for tinymembench numbers and you've the answer. The Raspberry Pi is a 2011 design (only ARM cores exchanged, everything else is still the same, just clocked slightly faster each year). It performs like that of course. Link to comment Share on other sites More sharing options...

I was so puzzled with the huge gap between the Pi's and the others, that I didn't notice the difference between regular/overclocked Pi3B+ and also between C2 and Rock64.

NicoD Posted April 9, 2018 Author Share Posted April 9, 2018 Indeed the ram makes the most difference. I've done tests with the Raspberry Pi 3B by overclocking the cpu and ram default, and doing blender and kdenlive. Then the ram overlocked to 515 in Ubuntu and cpu stock. The ram overclock did more than CPU overclock. At the end of this video you see the difference in overclocked to 1.35Ghz without ram overclock and with ram overclock. The difference is hughe.
