Raspberry Pi 4 vs Odroid N2

Unread post by naiboo » Fri Jul 12, 2019 11:00 pm

I´m sure you´ve noticed Raspberry Pi 4 was released some weeks ago.
Has anyone benchmarked / compared it to the Odroid N2? By the specs N2 seems to faster than the Pi 4, most major components are the same (usb 3.0, RAM specs, etc.). Wattage is also rather similar, N2 seems to be even lower than Pi 4 and the cooling solution on the N2 is epic; Pi 4 definitly need some active cooling or a big passive heatsink to avoid throttling!

I´m not quite sure which one to get to replace my Pi 2.

Depends on your use case. If you want built-in wireless and bluetooth, the Pi has it. If you want pure cpu performance, the N2 will be better. If you want eMMC N2, if not, then they're pretty equal. For price and the fact that Raspberry will be more mass produced most likely, and have more support for software/drivers, I'd go with the pi 4. If it was out when I got my N2 I probably wouldn't have got the N2.

But either one are good. I love my N2 and with some of the latest updates, Android and Ubuntu both run great on it.

pure computing power isnt what i´m looking for. I want a system on a SSD with usb 3.0. Both can handle this.
Anyone knows if odroid handles TRIM properly?
As already stated the community in pi is huge and this gives longterm support and lots of possiblities.
Phoronix tested both SBCs;

https://www.phoronix.com/scan.php?page= ... d-n2&num=1

the essence is that odroid is a bit faster but not too much ;)

Trim should work, but needs to be supported also by the usb-sata bridge and filesystem used.

unlike the N2, the pi-4 has thermal problems and can only use encrypted disks at usb2 speed.

The SD card slot is around twice the speed of the PI4 and both are below what decent SD cards can do in sequential read/writes so you will see a difference. In random read and writes the SD card is the limiting factor.

For me I want fast boot up without using a SSD and loads of CPU power so the N2 comes out on top, however the price shipped to my door is around 3 times as much compared to the pi4. Is the difference worth the price is something I am trying to answer so thanks for posting the links to the comparison benchmarks.

Love the form factor of the N2 and the proper heatsink design.

Bought pi4 for its dual display support. It couldn't even handle 480p youtube, so sold it right away. Happy with my N2 that can play 1080p youtube with software rendering. To me, it seems the performance difference is huge.

Just wondering if it would be somehow possible to connect two displays to N2.

I bought both mainly for chess-analysis. I'll post the StockFish benchmarks in a few days when my
booting card arrives. The best kn/s/dollar , kn/s/Watt give probably the Tablets with
Intel Atom Baytrail Z3735 processor (as in the "Atomic Pi")
with 1600kn/s for $50 while the Odroid-N2 has 2500kn/s with same Wattage but ~ twice as expensive
plus keyboard,booting card,power supply, monitor, no touchscreen,_time needed_ .
The pi3B gets 540kn/s going down to 400kn/s after a while without fan.
The pi4B gets a disappointing 1030kn/s at 6.9W going down to 940kn/s after 1hour with the small standard heatsink
(780kn/s at 5.7W without heatsink , stable at 1060 kn/s with a mini-fan at 6.9W (including fan))

The recent new chess or Go programs run on graphiccards ... can it be done with the Odroid ?

------------edit-----------------------------------
with cfish compiled on the odroid-n2 I get 2350kn/s on the n2 and 1850kn/s on the pi4b
in the Manjaro ARM operation system (similar to Arch Linux)

odroid-n2,4*A73@1.8GHz+2*A53@1.9GHz,cfish=2350kn/s(on 4 threads, only small increase when running on 6 threads)
Raspberry pi 4b,4*A72@1.5GHz,cfish=1850kn/s

I would expect the n2 to be at least 30% - 50% faster in cpu tests. The n2 uses newer faster A73 instead of older A72 in the pi4 and the n2 has two extra cores. Just waiting for a head to head comparison to confirm how much faster the n2 is.

The ODROID N1 turned out to be faster in single core performance than the ODROID N2 although it's using the what you called "older" Cortex-A72, and it's also using slower RAM than the N2.
Still in single core performance the N1 was actually faster than the N2.
The RPi4 will be slower than the N2 for sure, but I doubt it's going to be 30~50%.

It is indeed possible since I just did it. However, its currently not practical.

I just happened to be evaluating a USB3 (not USB-C) to HDMI dongle for a project. The dongle is based on the Fresco Logic FL2000 chip:
http://www.frescologic.com/product/single/fl2000/

I compiled a driver and test program that can be found on github and tested on N2:
https://github.com/FrescoLogic/FL2000

The second monitor correctly displayed the 1080p@60 and lower test images. However, at 1080p there is some glitching visible when using a USB3 attached device (SSD) due to bandwidth/timing constraints. Another limitation is that the driver is neither KMS/DRI nor FBDEV. It is not capable of displaying a desktop in its current configuration.

IMHO, biggest advantage of Pi4 is larger community suppport. Since Pi is here for a long time, it has army of supporters and there will be a lot of software packages and images for all possible uses, even for non Linux experts like me.

However, I want upgrade from my Pi3 which is now my main KODI and emulation device - I need UHD 60FPS, all HD audio passtrough capabilities, better support for emulation of newer consoles like Saturn etc. In this moment, Pi4 is no beter than Pi3 for this use and it seems to me that it will take a long long time until Pi4 gets all necessary support for this.

Therefore, my choice is clear and it is N2.

The real biggest advantage of RPi4 is the software support and the dev community.

Odroid N2 hardware is better than RPi (CPU and GPU) but Odroid software support is just a kind of joke.

How many USB3 4+GB RAM ~<100 $ SBCs can do that?
( honest question because odroid has the best community IMO so I really did not look much further )

Here is a joke for you; why was "rpi f/t" 5 years late to the 2+GB RAM and USB3 game; because they want to drain every last $ from their users before offering them the next crumb. (they can't even be botherd to put proper cooling or crypto on the pi4).

For sure! How much does two PCB holes cost? And, no crypto... :roll: As well as their forum being aggressive or barring their own users if they don't like your legitimate question or concern. No thanks!! I'll keep my N2 and the Odroid forum. Lots of great development, support and projects being done here!

And to be fair there are 4 holes in the PCB. It's just very difficult to use them with a standard heatsink mount pattern. :)

RPi Foundation is a charity. Every RPi you buy is one that a child is deprived of. There are 27 million children who will go to bed hungry and without the chance of an education because greedy people bought RPis. If you buy a RPi, then are you exploiting children.
:lol:

[edit]
The above is sarcasm as even the RPi Foundation is no longer pretending they are a "charity"[1] unless their goal is to ensure children have an education in digital signage skills.

[1] Here is the USA we call it a "non profit" which is a more accurate description. There are no Nuns giving meals and RPis to needy children.

Well, it is just pragmatism. I try to find equilibrium between hardware and software support.

I am not a RPi or Odroid fanboy.

Odroid could be much better with better software support. That's all.

@easybob95,
I've owned many different RPis and ODROIDs. ODROID-N2 is quite nice for playing 4K HDR movies with CoreELEC/Kodi as well as playing high end emulation games such as N64, PSP and DreamCast with emuELEC and Batocera.
Android 9 OS is very useful for many application too. My poor RPI4 can't do that at this moment.

Were you satisfied with the RPi's VideoCore OpenCL driver for your OpenCV project?
If you need a fully GPU accelerated OpenCV, you should choose the NVIDIA Jetson Nano board instead of the RPI nor ODROID since their GPU doesn't work well with OpenCV TBB libraries. NVIDIA's CUDA seems to be the best one for the vision computing as far as I know.

I don't know why is everybody speaking about that N2 is twice more expensive. In Europa (Austria) this is not the case.

Lowest price for Pi4 (4BG model) that I could find is 56€ + 7€ delivery (which will happen begining/mid of August). On top of it is mini to nomal HDMI converter for 6€ and cooler ~10€ (from my experience with Pi3 this is a must). This brings us to 79€ and I can have N2 for 100€ (inclusive delivery) in 2-3 days.

Actually, my biggest wish for N2 is Retropie support. It seems that setup script is failing because some dependancies and Retropie team cannot solve this. If someone from Odroid could help, it would be great

Raspberry Pi 4 is the beginning of the end for "The Foundation". The competition has taken its toll on their market. The RPi4 was rushed and released six month early to even keep them in business. Unfortunately, in their haste, it has a defect. This means that all the units currently sold may be returned when the next revision is released mid October.
https://www.raspberrypi.org/forums/view ... 5#p1501317

The typical life span of an ARM SBC is 2.5 years. There is no further room to "grow" with the RPI4 architecture. Another die shrink would be required to have any meaningful improvement. They can't upgrade ARM cores or increase speed since even the current product is thermally constrained. Assuming a core upgrade were to happen, the memory controller would still need a redesign to accommodate it. The current cores are bottlenecked by the lack of memory bandwidth.

In the interim, I doubt that the competition will stand still. They keep raising the bar higher and higher while RPi4 can only compete on cost. The RK3588 (A76/A55) is already announced and expected next year. I don't expect the "sugar rush" is going to last as long as RPi expects it to.

So, imagine you are a RPi reseller and suddenly the RPi4 is announced. Your entire stock (thousands) of RPI3s are now obsolete. Not only has the value diminished, but they are also taking up warehouse space. As RPI4 sales begin, a defect is found rendering every sale subject to return and/or replacement under law.

Fortunately, history provides a recommendation for what to do with all the unsold RPI3s and defective RPI4s:

Hello stmicro,

i just used RPi 3 B+ and i am very pleased with it. Concerning CPU ang GPU power, of course, it is very weak for my project. But my project also needs GPIO and considering everything, the RPi3 is really interesting with rather interesting hardware and very good software support.

Concerning N2, CPU is really good and N2 is more suitable for my project (image treatment with opencv). Concerning N2 GPIO, the python library is very bad and for now, i don't consider using N2 GPIO becaus i would have tore write to much things to use it (too much time to spend on this).

Jetson Nano is the good choice for high performance image treatment with Cuda. I start working on it and i must say it is really interesting. A very beautiful project for me.

I don't know why is everybody speaking about that N2 is twice more expensive. In Europa (Austria) this is not the case.

Lowest price for Pi4 (4BG model) that I could find is 56€ + 7€ delivery (which will happen begining/mid of August). On top of it is mini to nomal HDMI converter for 6€ and cooler ~10€ (from my experience with Pi3 this is a must). This brings us to 79€ and I can have N2 for 100€ (inclusive delivery) in 2-3 days.

Actually, my biggest wish for N2 is Retropie support. It seems that setup script is failing because some dependancies and Retropie team cannot solve this. If someone from Odroid could help, it would be great
the pi4b-1GB ships for 35 Pounds=39 Euro. A power-supply is ~5 Euro . You can buy 100 such units for 4400 Euro,
and boot one after the other with 1 mouse, 1 keyboard, 1 booting card , 1TV and run some program on each.
After a year you check the results ... . 4500Euro + 1300Euro for power. Well, maybe plus 500Euros for heatsinks or coolers.

The odroid-N2 costs 80Euro plus 6Euro power supply. 100 systems make 8700 Euros + 1500 Euros for power for 1 year

6300 vs. 10200 , will the odroids do >50% more calculations ?

prices are, what they cost in Germany including custums,taxes,shipping

Well, to begin with, you should compare the prices of 2GB/4GB models.

Adequate coolers for 5 eur a pop? The pimoroni shim one goes for >10 eur, so good luck with that!

OK, I take one of those :

https://www.ebay.co.uk/itm/Silver-Tone- ... %7Ciid%3A1

and on top of that I place one of those :

https://www.ebay.co.uk/itm/100x100x18mm ... %7Ciid%3A1

That should give twice the cooling power of the Odroid-N2 for 5Euro
I may have to remove one of the 2 white bars with a tong, I don't know what they are for.

No way to reduce Pi4 temperature with passive cooling. I tried it with Pi3 and it was just a waste of time.

You need real fan for this and this definitelly costs more than 5€.

Also, descent power supply for Pi4 costs more than 5€ - original is ~9€.

Please make realistic comparation of price with equivalent models - compare pricing of 4GB N2 and 4GB Pi4.

I'm afraid thermodynamics does not work like that (hint: stacking radiators over radiators *reduces* the dissipation power of the system).

Just sitting there doing nothing, RPi 4 seems to stabilize about 46 degrees. In a case it would presumably be higher. I think ambient in this room is about 16. N2 is at 26 degrees.

At completion of stress-ng --matrix 0 -t 1m, RPi 4 at 60, N2 at 37.

At completion of stress-ng --matrix 0 -t 5m, RPi 4 at 71 deg, N2 at 42 deg.

Wow. Where do you live? /envious

ps: Speaking of envy, my 1990's stepping-into-3D-accelerators self would've been absolutely floored that my 2010s self would be running 4K @ 60fps @ 16x MSAA OGL* on a passively-cooled device costing $80.

Some comparisons here and shows the N2 is faster and cooler.

... and its over as soon as it began...

Raspberry Pi 4 is dead!

Eric has decided to join Google as part of their growing Chrome OS graphics team.
The ONE guy they had doing the GPU work on it is now at Google working on Freedreno instead.

Well, Eric Anholt himself isn't that pessimistic:
Sometimes you have to look beyond the forest to see the trees. The relevant part is that Broadcom is not replacing him. This means they are now de-funding the Raspberry Pi subsidies. This also clearly indicates why the launch was so premature: there is no longer an interest at Broadcom for it - release or die. Now that Raspberry Pi has to pay their own bills, I do not expect it will be around for much longer.

Oh, look at the design, you can't put a heatsink on the RK3399 and use the NVMe socket at the same time...?!

Try using the NVMe socket on the Pi..... Oh , wait.....
My point was the new Pi 4 is already lag'n. Even in the same foot print and price range.

@crashoverride: did the guy who's leaving have access to NDA information, or was he reversing proprietary stuff with a blackbox approach - about the same way you're doing with Amlogic stuff?
If he had NDA clearance then I agree, he'll be harder to replace by the community...

Since the GPU docs for VC6 are not public, he would had to have access to the internal Broadcom references, as well as existing source code, and the ability to phone/email any work colleagues should any questions arise. Anyone outside the company would not have this same level of access.

It would not surprise me at all if Raspberry Pi is already shopping around for someone to buy them out. I am sure all the young talent have already begun looking for work elsewhere, while the 'old VideoCore guys' will simply end up getting laid off. Any potential buyers would be interested in the brand only. The old hardware designs are obsolete, and the new design barely functions. So, I doubt anyone would want the cost and burden of such a proprietary chimera.

One of these 40x40x20 mm heatsinks for $1.50 was enough to prevent the pi4b from heat-throttling,
although the thermometer-warning kept showing up on the monitor. Two of them obove each other made
the thermometer disappear. Running for days... stable.
The reason why I get 2500kn/s with the odroid-n2 and only 1050kn/s with the pi4b is presumably
that the pi is running in a 32-bit OS while the odroid in Android under Droidfish uses 64-bit ?!?
I also got a little fan for the pi for $1.20 and I think this is the better solution for most purposes

Which temperature your Pi4 reaches in this construct?
