Benchmarking CPUs

100% meaningless numbers now since they do not provide any insights any more (you can not differentiate what's throttling and what's -- potentially inappropriate -- cpufreq scaling behavior).

 

 

For two simple reasons:

  • allowing very low cpufreq OPP trashes performance (on your Tinkerboard it's storage performance due to the clockspeeds not increasing fast enough)
  • the way DVFS works at the lower end of the scale the differences in consumption and generated heat are negligible between silly ultra low MHz values and a reasonable lower limit (we in Armbian TEST for stuff like this with every new SoC family!)

Closed your issue right now spending additional time to explain: https://github.com/ThomasKaiser/sbc-bench/issues/4

 

 

So you're suggesting your benchmark script is meaningless?

 

I don't think so - it's very useful... and can be more useful in doing A/B testing  - rather than set params, report them - and let the tester review and test as needed.

 

the rk3288-tinker was armbian stock clocks - no tweaks there... it's just hopelessly impaired in a multiple thread environment - it gets heatsoaked, and no chance to recover with stock armbian - the numbers show that.

 

The whole rk3288-tinker problem is something that is really driving me how to sort it - using what is on hand, and no code-impact to armbian - so going down the road of how to make the best use of resources available... Challenges at the moment with tinker is that armbian does do the lower limit, and still sorting out if the DT updates on mainstream have been pulled in as 4.14 has a lot of changes on the mainline.

 

Hint on today's testing - I chose the Allwinner H3 device from FA - the NEO, as this is a well tested device (as you know) - just playing around with CPU schedulers... if you want the worksheet with backup on the testing - reach out to me directly...

 

Yes - I know UnixBench is kind of relative - useless across different machines/platforms - but in relative testing, with the same board/kernel/compiler, it's very useful - as you can see the time to complete the actual test, each sequence is almost an hour under test - so fair chance that thermals would be the biggest problem...

 

The NEO H3 - It doesn't throttle, but it's a fast race to minimum across performance/ondemand/schedutil... single thread shows some regression, but four threads bear interesting stuff when doing some fun with UnixBench... as you can see on the timeline - more than enough time for the H3 to get throttled, but it never does... did performance as a parity/sanity check - but the sample sizes across the benchs do suggest a high confidence interval on the results.

Last run - I pushed the H3 into powersave to bring the clocks down, otherwise it would have been 4 cores running at max - 4 cores burning on performance, I suppose temps would have eventually come down - I let it run a bit - did a stint in powersave mode to get to a good entry point for temps at 40C on for a good entry point on ondemand and schedutil - they would always jump down to minclock there - perf wants to be fast in single thread - but these days... and with big.little, woe to be the kthread on the wrong core...

NOTE - I've highlighted the performance regressions across things... and they deserve further study. With cpufreq schedutil, might improve...


Looking forward - getting to a point where benchmarks can be useful, automated, and reproducible... ARM's LISA looks really good for the CI workflow - and it opens up the black boxes that most benchmarks do...

All told - upcoming items like affordable big.little boards, preempt-rt, and cpufreq coming into play is going to complicate things... it's the upcoming perfect storm for the team, so get ahead of it...

 

I'm here to help - not trying to get into conflict - I've got more than a fair amount of time doing embedded stuff on arm - on QCOM, Marvell, Freescale, and TI - android and emdedded - I'm not crazy like the stuff over on xda, where things go strange.

 

I'd rather work with you than against you - against you, I'll lose, that's true, but the community might also lose on the investment of my time and effort to contribute.

I've just finished Benchmarking most of my sbc's.

This is done to see how well benchmark tools perform.
Conclussion is that I've found no perfect cpu-benchmark tool. With every tool there is a problem.

 

7-zip does good in single core tasks(100%) but with multicore tasks it doesn't use 100% of all cores. This percentage also differs from distro and from sbc to sbc. It also does a little bit better on 32-bit systems.
With blender different versions perform different. Older versions are faster. It also performs a lot better on 64-bit.
Sysbench does different tasks with different versions. It performs about 10x better on 64-bit systems.
CPU-Miner only works on 64-bit systems. It performs best on Bionic.
Gimp only uses 1 core. Performs better on 64-bit.
GTKPerf tests desktop speed. It only uses 1 core. It doesn't give reliable information.

Here all my results. I'll make a video about it by the end of the week. If anyone has suggestions. Please let me know.

Reasons why benchmark tools can give different results
------------------------------------------------------
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 uses recources

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.
Blender works a lot better on 64-bit than on 32-bit. It uses 100% of the cores.
Sysbench works 10x better on 64-bit, different versions give different results. Version 1.xx does the test 10s and gives the amount of events.
GIMP only uses 1 core, works better on 64-bit.
GTKPerf tests desktop speed. It only uses 1 core.
CPU Miner only works on 64-bit. Works better in Ubuntu Bionic than in Debian Stretch/Ubuntu Xenial.

Blender : BMW render @ 1080p
Gimp : BMW render result 1080p Filters -> Artistic -> Van Gogh -> ok
Sysbench : sysbench --test=cpu --cpu-max-prime=20000 --num-threads="number of threads" run
7-zip : Numbers are average of 3 of decompressing only

All tests are done with a fan when necessary so no throttling occurs.

Some benchmark tools can give an estimate of the performance. But they are never an exact reflection.

I've just finished Benchmarking most of my sbc's.

This is done to see how well benchmark tools perform.
Conclussion is that I've found no perfect cpu-benchmark tool. With every tool there is a problem.

 

Well - benchmarks are going to try to measure something specific...

My video about benchmarking CPU`s of SBC`s.

 


Here all my data gathered
 

Reasons why benchmark tools can give different results
------------------------------------------------------
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 uses recources

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.
Blender works a lot better on 64-bit than on 32-bit. Older versions are faster. It uses 100% of the cores.
Sysbench works 10x better on 64-bit, different versions give different results. Version 1.xx does the test 10s and gives the amount of events.
GIMP only uses 1 core, works better on 64-bit.
GTKPerf tests desktop speed. It only uses 1 core.
CPU Miner only works on 64-bit. Works better in Ubuntu Bionic than in Debian Stretch/Ubuntu Xenial.

Blender : BMW render @ 1080p
Gimp : BMW render result 1080p Filters -> Artistic -> Van Gogh -> ok
Sysbench : sysbench --test=cpu --cpu-max-prime=20000 --num-threads="number of threads" run
7-zip : Numbers are average of 3 of decompressing only

All tests are done with a fan when necessary so no throttling occurs.

Some benchmark tools can give an estimate of the performance. But they are never an exact reflection.

Now too late. I`d need to prepare every image again. I can always add it later. I`m done for a while with benchmarking. It ain`t much fun.

 

that's ok, but what I have found is that UnixBench a good equalizer across different SoC's on these cheap little boards - even though UnixBench is still variable based on the compiler...

 

It runs long enough (a full run can be 28 minutes) to show if thermals are a challenge (for TinkerBoard, absolutely with stock config compared to NanoPI NEO, where the Tinker has a much better architecture (A12) vs. NEO with A7, but the Neo can shed heat faster, and outperform the Tinker in the longer run - heck, even Pi3B+ runs UnixBench faster than Tinker...

In order to leverage on hw crypto engine, I had no choice but to use OpenSSL 1.1.1 lib (openssl-1.1.1-pre8) and I decided to use cryptodev-linux instead of AF_ALG since it gives me slightly better result (+5-10%).

 

Something is wrong with your numbers...

 

Armada 3720 without CESA - running the 3720 at 1GHz... all core - it's been my experience that the crypto accelerators are more of an offload rather than make things fast as arch's update and include instructions that support crypto...

CESA makes a lot of sense with the ArmadaXP and Armada 38x as older ARM - ARMv8/aarch64 can change things quite a bit...
