Re: Raspberry Pi 4 vs Odroid N2

My 2 cents on the matter.
I've been a huge, huge fan of RPi. I own various 0, 0W, (1)A/A+/B/B+, 2 and 3. Love them all.
I used RPi for case studies and for commercial applications (many are around the world doing stuff).

But then I purchased a couple 3B+, because 2B and 3B were no longer available.

I deeply dislike the 3B+ and I would probably dislike 4 too, for the same reasons: may too much power draw and heat vs. performances.
Moreover, at least my 3B+s show erratic performances despite using "performance" governor, "force_turbo=1" (don't to that at home, you'll lose warranty), a beefy 3.5A stabilized PSU and an hefty heatsink (and no overclocking).

Switched to Odroid N2 and I'm sooo happy. Dream machine. If only it was a bit smaller and cheaper.

That's my own opinion, your mileage may vary.

"a bit smaller and cheaper" than the N2 is the C4.

Howdy, I'm a pi4 convert. On the pi, I've been running raspbian, openvpn, a deluge torrent client, and a Plex server. The pi was awful for decoding video. May someone point me in the direction for doing this on the n2 or in tandem with the pi4? Should I go Ubuntu? Do I go coreelec (but what about openvpn, plex and torrents)? Thank you!
You can try Armbian. In Debian (Raspbian) or Ubuntu variant. With improved stock or improved mainline kernel. https://www.armbian.com/odroid-n2/ (Don't worry about label testing, its at least as good as stock)

Excellent board (was not even talked about, when I purchased my N2), but a bit too slow for my needs.
Still very, very nice. I may end up buying one just for the sake of it!

Too quickly. Their normal cadence is 2 1/2 years. In a very short time, they have had to drop the price of their boards and now introduce PI+ early. These are all signs of a struggling company. My bet is they are fixing to sell off the brand name and exit the business.

Unless the 8 GB model pays off big, you know all those kids in third world countries using Pi's need 8GB of RAM.

Could be. In this context it is hard to ignore that RTOS part of the Pi is already owned by Microsoft, embrace extend extinguish ... :( IMO very little % of people actually need this much memory but big numbers are best selling hook ...

The most popular piece of software is the web browser and It also happens to be one of the most memory consuming. People don't know how to manage their tabs properly (selecting and bulk bookmarking) so they complain that their computer gets slow with 99 tabs open for later reading. Personally Eclipes, git, and VMs make 4GB just not enough for desktop use. That said I don't expect the average person to require more that 8GB in the near future. But are any of us here really average? Anyway H2 is shipping again soon for those in need.

Thing is that it was planned all along to release the 8gb variant so I am not so sure about signs being a company in trouble or possibly on exit.

Well I'm sure they had a business plan that involved milking every model to the max. It took them five years to catch up to odroid with USB3 and Eban works at broadcom. Whether or not this is a late release or an early release it does seem slightly unusual given their history. Anyway competition is good maybe the rpi4 will get a good official thermal solution next.

    They already sold 3 million rpi4 and they start to implement vulkan driver, I think the 8gb model will pay off too

      I think it will do well also, but the question is where do they go from there.

      Well vulkan will not be done in one day, I am curious how long it will take them to implement it, so I think it will be software optimizing and squeeze out the rest of performance of this little thing like they did the last years, they already have a wide area of hardware add-on's they and the community and there third party HW manufacturers just have to maintain this and all will be good.

      If I go to an electronic specialized store here in austria they all have a complete shelf full of RPi stuff and add-on's

      IMO it is usually beyond the technology. RPi is a consumer oriented product with a great marketing, virtual market monopoly and huge and illiterate crowd of believers which will never learn much of Linux. An (Apple like) church. They buy everything that has association to Pi without questioning. If their NAS/project is working slow/bad, they blame themselves for not getting the job done properly. It's never Rpi's fault ...

      Yeah it's not like that here in the US, you can only get a Pi online and the sites selling them always upcharge.

      It would cost me $19 just to get a Pi Zero W.

      After experiencing an astonishing load level of 2 when idle, I downloaded Armbian and tried the experimental 5.x kernel. I did not install a desktop or test video playback. With Armbian the systemd got stuck in a loop when I had a monitor connected and consumed about 15% CPU. This problem went away when I disconnected the monitor. There were no crashes and it's been running very reliably as a NAS with only Ethernet and an SSD for a couple weeks.

      For the original post, it's worth noting that the Raspberry Pi 4B is very different than the 3B+ from a performance point of view. True gigabit Ethernet, a PCI express lane for USB3 and Cortex-A73 cores (same as the N2) results in very good performance.

      From a size, price and performance point of view, the Odroid-N2 is bigger, more expensive and faster than the 4B while the Odroid-C4 has similar size, price and performance. From recent experience, the main differences between the C4 and 4B may be summarized as follows:
      • The A73 cores on the 4B are faster than the A55 cores on the C4.
      • The two-chip memory system on the C4 has more bandwidth than the single chip solution on the 4B.
      • The C4 runs from 12V which is easier to supply than the 5V needed by the 4B.
      • The 4B includes a free license to the $2870 Mathematica computer algebra system while the C4 doesn't.
      In my opinion, any or none of the above items could be a decision-making factor depending on particular usage. It's great to have great choices.

      More details on my analysis of the performance of the C4 compared to 4B are included in the post

      It would be real nice if a similar deal could be worked out for the N2.

      I'm not sure why one wouldn't connect a monitor to an N2, but did acknowledge a computer algebra system might not be a deciding factor for everyone.

      Mathematica can be used server side as a domain-specific language as Wolfram Script, or through xorgxrdp and VNC if you still want to use a mouse. Most of the programs listed as alternatives are not computer algebra systems. While the difference is no worse than trying to use gimp as a pdf viewer (thanks Firefox), the failure to note the difference further highlights that Mathematica could not be a deciding factor for many people.

      Among alternatives on that list, there is actually only one open-source computer algebra system: Maxima dates back to code written in the 70's at MIT called Macsyma. This particular program appears difficult to maintain and over time has lost features and returns more wrong answers. Fortunately, there are other open source computer algebra systems that were left off the list. These include Reduce, Axiom and Fricas. Reduce enjoys even less maintenance than Maxima while Axiom and the related Fricas have an amazingly difficult type system that makes casual use difficult.

      This leaves the commercially developed Mathematica and Maple as the only two computer algebra systems convenient and powerful enough for people learning next-generation mathematics. Maybe Odroid could instead look into providing a free license for Maple. People have different interests and needs, that's why it's great to have great choices.

      Was really thinking into buying an Odroid-C4 for using a mathematics software system. I finally decided for a Rpi 4 8Gb mainly because of wolfram mathematica 12. My Odroid-N2 is still working as a NAS/media server at home but no longer serves as a main desktop replacement.

      Maybe this is a better list;

      Looks like some people have been working on a comparison;

      From that it looks like Open Source has all of ones CAS needs met.
