ODROID beats them all !

Unread post by harry4516 » Sun Feb 08, 2015 1:48 am

During the last few months I have bought many of these little ARM boards.
Now it was time to make a simple performance test (single core) to compare the systems.
This test was done with this command:

Code: Select all

time echo "scale=4000; a(1)*4" | bc -l
this simply calculates the number PI and prints the time needed. It is a nice and simple way to compare the speed of a single processor core.
this code was found here:
http://akaul.de/linux-cpu-benchmark-fur-die-console/

Single Core Results:

i7-3770 ... 9,4s (Intel, my bolide desktop machine, 3,5 GHz)
ODROID XU3 ... 29,1s (Exynos 5422, Cortex-A15 & Cortex-A7, 1,8GHz)
ODROID U3 ... 35,3s (Exynos4412 Prime Cortex-A9Quad Core, 1,7 GHz)
ODROID C1 ... 48,5s (Amlogic S805 Cortex A5, Quad Core,1,5 GHz)
Banana PI M2 ... 1m 18s (A31, Quad Core, 1GHz)
Banana PI ... 1m 18s (A20, v7dual, 1GHz)
RaspPi-2-Model-B ... 1m 42,5s (BCM2836 v7quad, standard clock setting)
PaspPI-ModB ... 2m 23s (ARM11, 700MHz)


All Core Results (smoothed values of parallel tests):

i7-3770 ... 1,2s (Intel, my bolide desktop machine, 3,5 GHz)
ODROID XU3 ... 4,85s (Exynos 5422, Cortex-A15 & Cortex-A7, 1,8GHz)
ODROID U3 ... 8,8s (Exynos4412 Prime Cortex-A9Quad Core, 1,7 GHz)
ODROID C1 ... 12,2s (Amlogic S805 Cortex A5, Quad Core,1,5 GHz)
Banana PI M2 ... 19,5 (A31, Quad Core, 1GHz)
RaspPi-2-Model-B ... 25,6s (BCM2836 v7quad, standard clock setting)
Banana PI ... 39s (A20, v7dual, 1GHz)
PaspPI-ModB ... 2m 23s (ARM11, 700MHz)


The ODROID XU3 is a fantastic fast computer, only 1/3 of the speed of my expensive desktop machine.
The banana PI is also quite good for most applications.
I am disappointed about the brand new Raspberry PI2ModB, which is surprisingly slow.

So the XU3 is the board of my choice for most applications, well done Odroid guys, and be motivated to build an even faster one, hi.

On U3 with CPU temperatures.

"tmpr" is alias for cat /sys/class/thermal/thermal_zone0/temp.

$ tmpr;time echo "scale=4000; a(1)*4" | bc -l;tmpr
32000
<Pi number here>*
real 0m35.257s
user 0m35.255s
sys 0m0.000s
37000

Room temperature is 18 C, passive heatsink from Zalman, board not in the case, Ubuntu Server OS.

..................................................
*I am wondering if the number is calculated equally on the different Odroids.
The last digits here are

Vort, could you please post a picture of your Zalman mounted on the U3 ?

and yes, the last digits are the same.

By the way, I stopped further testing with the new Raspi2-ModB. This board is not just slow,
it also freezes twice a day, even with a low clock.

I recently tested the new Lemaker HiKey which uses an A53, 64bit, 8-core running at 1,2 GHz.
Here are the single core test results:

i7-3770 ... 9,4s (Intel, my bolide desktop machine, 3,5 GHz)
ODROID XU3 ... 29,1s (Exynos 5422, Cortex-A15 & Cortex-A7, 1,8GHz)
ODROID U3 ... 35,3s (Exynos4412 Prime Cortex-A9Quad Core, 1,7 GHz)
Lemaker HiKey ... 45,3s (A53, 64bit, Octacore, 1,2GHz)
ODROID C1 ... 48,5s (Amlogic S805 Cortex A5, Quad Core,1,5 GHz)
Banana PI M2 ... 1m 18s (A31, Quad Core, 1GHz)
Banana PI ... 1m 18s (A20, v7dual, 1GHz)
RaspPi-2-Model-B ... 1m 42,5s (BCM2836 v7quad, standard clock setting)
PaspPI-ModB ... 2m 23s (ARM11, 700MHz)

I could not believe it, so measured it a couple of times.
The board is not much faster then the Odroid C1.

Odroid has still the best performance of all SBCs in the market.

That's actually no wonder.

ODROID C1: 1500 * 1.57 DMIPS = 2355
Lemaker HiKey: 1200 * 2.3 DMIPS = 2760

So they are nearly identical in speed, but seeing that there are A53 cores that come with a stock clock of 1.6 GHz as well:
1600 * 2.3 DMIPS = 3680 it's easy to see, that they get quickly much faster than a Cortex-A5 as used in the C1. Even overclocked at 2GHz the C1 only reaches 3140 DMIPS.

But both cores (A5 and A53) are still rather slow compared to a Cortex-A9, A15 or a A57 (and there are even faster cores).

But since there are ODROID boards with A9 and A15 cores out there, yes, that means ODROIDs are really kick ass fast boards :D

Really a newer snapdragon board such as the 810 will outperform the XU4 but at a much higher cost.

The Nvidia TK1 will also perform better, but once again it's double the price of an XU4.

For the money it doesn't get better than the C1+, U3 (retired), and XU4

Is this test CPU Governor & frequency bound?

The XU4 defaults to performance so the governor isn't relevant.

Of course it's frequency bound, it's a CPU benchmark ;)

Yes, but I use interactive with scaling_min_frequency = 800 mhz on all cores. This is why I was asking.

since there is a 64bit Rapi-3 available, it is interesting how it performs with it's 32bit OS (single core).

i7-3770 ... 9,4s (Intel, my bolide desktop machine, 3,5 GHz)
ODROID XU3 ... 29,1s (Exynos 5422, Cortex-A15 & Cortex-A7, 1,8GHz)
ODROID U3 ... 35,3s (Exynos4412 Prime Cortex-A9Quad Core, 1,7 GHz)
Lemaker HiKey ... 45,3s (A53, 64bit, Octacore, 1,2GHz)
RaspPi-3-Model-B ... 45,9s (A53, 64-bit, Quadcore 1,2 GHz, 32bit-OS)
ODROID C1 ... 48,5s (Amlogic S805 Cortex A5, Quad Core,1,5 GHz)
Banana PI M2 ... 1m 18s (A31, Quad Core, 1GHz)
Banana PI ... 1m 18s (A20, v7dual, 1GHz)
RaspPi-2-Model-B ... 1m 42,5s (BCM2836 v7quad, standard clock setting)
PaspPI-ModB ... 2m 23s (ARM11, 700MHz)

The 32bit OS is the same as for the Raspi2B, so we can see the difference between the CPUs.
It looks like that the A53 is doing a good job.
In a few weeks the Odroid C2 should be available with a real 64bit OS, I am really excited how this board will work.

If someone has an C2 already, could you post the output of:
time echo "scale=4000; a(1)*4" | bc -l

i got 41.8s on the C2.
Interesting to see, that the old U3 SoC is faster than a current ARMv8 CPU which is even higher clocked. But I guess that's cause A53 are slow cores (comparable with Cortex-A7 I believe)

the C2 just arrived, its now available from Pollin.
Lets complete the list with the C2:

i7-3770 ... 9,4s (Intel, my bolide desktop machine, 3,5 GHz)
ODROID XU3/4 ... 29,1s (Exynos 5422, Cortex-A15 & Cortex-A7, 1,8GHz)
ODROID U3 ... 35,3s (Exynos4412 Prime Cortex-A9, Quad Core, 1,7 GHz)
ODROID C2 ... 41,0s (Amlogic S905 A53, 64bit, Quadcore, 2 GHz, 64-bit OS)
Lemaker HiKey ... 45,3s (A53, 64bit, Octacore, 1,2GHz, 64-bit OS)
RaspPi-3-Model-B ... 45,9s (A53, 64-bit, Quadcore 1,2 GHz, 32bit-OS)
ODROID C1 ... 48,5s (Amlogic S805 Cortex A5, Quad Core,1,5 GHz)
Banana PI M2 ... 1m 18s (A31, Quad Core, 1GHz)
Banana PI ... 1m 18s (A20, v7dual, 1GHz)
RaspPi-2-Model-B ... 1m 42,5s (BCM2836 v7quad, standard clock setting)
PaspPI-ModB ... 2m 23s (ARM11, 700MHz)

I tried three 64 bit boards with these results:
RPI-3 ... working stable, but 32 bit OS only, slowest of the three boards boards
HiKey ... Ubuntu 64-bit implementation is a mess, almost nothing is working, not even the basic functions
ODROID C2 ... Ubuntu mate 64-bit is working stable, most applications are working (not all), fastest of these boards

Hardkernel, you are doing a good job, keep up the good work !
I'm very excited to wait for your next Ubuntu release

One thing I can't understand. Looking at the 2 GHz clock of the C2 it should be about 1,6x faster compared to RPI3/HiKey running at 1,2GHz.
But it is only 1,12x faster. Whats the mistake ?

Maybe performance isn't linearly related to the time result? Because the XU3 only gives about 40% shorter time, but I keep reading that the performance difference is much greater than that.

The xu4 will always throttle with the stock setup, I can lower the maximum frequency of the A15 cores to 1.6ghz and outperform the stock heatsink with fan using an improved fanless heatsink.

the C2 runs at full 2GHz speed, no throttling.
It looks like the CPU is not as fast as expected for a 2GHz machine.

the clock speed is not everything. You also need to add the instructions per seconds PER clock into your equation.

The Cortex-a53 is aproximately as fast as a Cortex-A7 cpu, that's why the 4 year old U3 still can surpass the C2.

ODROID XU3/XU4 ... 23.2s (Exynos 5422, Cortex-A15 & Cortex-A7, 2,0GHz) ---> (as 2GHz is the default clock not 1,8GHz)

Also you might want to correct your C2 clock speed to 1.5 GHz as it turned out the C2 had a fake clock speed ;)

How does the RockPro64 and ODROID N2 compare?

I'll be getting one or the other in around a month.

maybe you see it from the wrong side... instead of "how can others be so good" consider asking "could it be that the N2 is really that bad?"
Even the XU3/XU4 can beat the N2 and it's has on paper "slower everything" (RAM / CPU / architecture) and it's a 5 years older hardware but still beats the N2.

The XU4 uses much more current to do so and is clocked 200mhz faster, it's not the N2 is bad it's the XU4 is that good.

I'm still hopeful for an Exynos powered XU5 eventually, until then the N2 suits my needs. But I don't use USB, if I did the N2 USB problems would be a huge issue. I wonder if the updated Amlogic SoC has this same problem.

Clock speed has not "that much" to do with it, it still depends on the instructions per clock the SoC can handle, and "on paper" the N2 can do more than the XU4 here:
https://en.wikipedia.org/wiki/List_of_A ... hitectures
A-15 -> 3.5 / 4.01 DMIPS/MHz
A-73 -> 4.8 DMIP/MHz
1704 MHz x 4.8 DMIPS/MHz = 8179
2000 MHz x (3.5) 4.01 DMIPS/MHz = (7000) 8020

So ON PAPER the XU4 should be slower. Same goes for RAM, DDR3 vs DDR4, cache for instruction and so on.
Also:
N1 faster than N2 (although ON PAPER the N2 should be faster)
XU4 faster than N2 (although ON PAPER the N2 should be faster)
RPi4 faster than N2 (although same CPU and RPi4 is slower clocked and therefore should also be slower)

There's a pattern that you can see and it's not "the other boards are all so good".

I'm not arguing the XU4 shouldn't be faster than the N2, I agree. The small difference between them in this benchmark can be explained by the difference in frequencies though.

I mentioned power consumption because I'm my opinion it's impressive the N2 meets or exceeds the XU4 performance at around 1/4 the power usage. The VPU and GPU performance far exceeds the XU4, but until the N2 GPU is as useful on the desktop this doesn't really matter.

Samsung is far more experienced at ARM development than Amlogic, I don't think anyone would say otherwise. As we know they have lied about frequencies in the past. I think once the software matures the N2 will be better in all ways, that is as long as the USB problem can be fully fixed.

I don't look at the N2 as the new XU4, it's simply another Odroid device. The XU4 is my work horse, the N2 is my media consumption device. It is the new C2 in my opinion.

I like the low temperature of the N2 compared to the XU3/4. No additional fan is needed it keeps really cool even under load.

One of the most important things:
Instead of the SDcard I'm using a fast SSD connected via USB. (SDcard for booting only).
This makes the N2 much more responsive and more convenient to work with it.
(Of course, the same is also true for the XU4).
I'm using a 120GB SSD with three partitions, 30GB each.
sda1 is the usual working partition,
sda2 is a backup of sda1
and sda3 is a copy of the fresh installation on SDcard.
So if something goes wrong, I can simple copy sda2 to sda1 and all is running again in a few minutes.

this simply calculates the number PI and prints the time needed. It is a nice and simple way to compare the speed of a single processor core.
This doesn’t “simply” do the work... it is actually quite complicated! You’re launching several processes (time, echo, bc), creating a pipe (|), and actually running a very tiny calculation within bc... so much so that most of the time will be parsing the expression and traversing its representation. As a result of all this you’re not measuring much besides OS performance. This is a perfectly valid benchmark... but be aware of what it is measuring! The 64bit processors will likely be slower than the 32bit ones, if only because they have more overhead.

good remark, so I tested it and watched the processes running:
Only bc is running. The runtime of echo.. is extremly short and does not get into the results.

Yep, none of the work takes long enough to actually allow concurrency to happen... but most of the work is still loading executables, creating address spaces and threads and the pipe, etc. For my purposes it’s not a very interesting benchmark, but it depends on your typical workload(s). My N2 runs my applications and the compiler much, much faster than my HC1 and somewhat faster than my RockPi. From the compute benchmarks I’ve seen, I expect it’ll outperform the RPi4 too.

Be careful drawing conclusions from arbitrary benchmarks.

So you're saying all these boards need 20s just to load echo, and bc and their respective libraries?
Do you really believe that?
if that would be the case echo "1+1" | bc should take nearly the same time, as it has to load the same binaries and libraries and by your own words, that's "the most work" being done.

Agreed, this "benchmark" shows only one specific task and calculation. One that can be reproduced on nearly all system and gives only a comparison of a specific math operation, nothing else.
It doesn't utilize all CPUs, it doesn't work with huge amount of RAMs. It gives an impression of one single calculation and other tasks can run very differently as they utilize the hardware better than this single calculation.
Still for that single calculation it's a valid test to see how these board compare.

You are... confusing?

Let's rewrite that so bc is also measured separately by calling time (the program and not time the shell internal timing command) - as we add another process overall runtime increases slightly but we get another measurement:

Code: Select all

time echo "scale=4000; a(1)*4" | /usr/bin/time bc -l
gives on my desktop box:

Code: Select all

....
8.15user 0.01system 0:08.16elapsed 100%CPU
....
real    0m8,169s
user    0m8,154s
sys     0m0,018s
Total of all takes 8.169s, of which 8.154 is spent in userspace and 0.018s in kernel (=lauching processes, creating pipe, connecting programs)
The bc command itself takes the majority of that, total 8.16s, of which 8.15 is actually bc in userspace and 0.01 the system/kernel setting it up.

=>Kernel/system overhead is negligible, they are rounding errors, the single-threaded calculation by bc dominates them all.
So this is mainly a single-threaded CPU measurement if the kernel has all the programs cached and does not need any I/O.

Good points, thanks for pointing out my error... (I had misinterpreted the output dump and hadn't realized what the units were). So the bulk of the execution time is bc itself. To understand why it is slow will require delving deeper into its code. Given that it is using very large arbitrary precision numbers, most likely there are math operations being used that the A73 isn't especially good at or the code was compiled with optimizations set for a different core type. Don't know what this is offhand, but bc won't be using the FP or Neon units.

For fun, I use a mixed workload to get an overall first feel for a platform:
Compiling ripgrep from scratch and warm cache (cargo install -f ripgrep; time cargo --offline install -f ripgrep)
That's a single threaded (linking), multi threaded (compile) and I/O (lots of intermediate files) mixed workload using everything a bit.
Numbers for Rust 1.36+ripgrep v11.0.2:
0m43s -- 6-core desktop x86 (nvme SSD)
2m42s -- H2 (nvme SSD)
~6m40s-~7m02s -- HC1 (mechanical disk)
~13m20s -- C2 (microSD)
where there is quite some variance with HC1 (due to thermal throttling?).

did some work with the RPI4,
its a real heater, without doing anything the CPU gets above 60 degC after a short time, good SBC for winter time.
Even if the RPI4 is fast, a good heatsink and a fan is mandatory, therefore not a competition to the N2.

My N2 is running 24/7 as an SDR receiver and gets 35 degC maximum, without a fan, just with the standard heatsink.
I used the XU4Q before, but the XU4Q also required a fan for this SDR receiver job.

So even if the N2 does not outperform the XU4, the efficiency is much (!) better.
