Help me to benchmark Raspberry Pi 3 Model B+

[kirankankipati]

Hi guys,

I do not have currently Raspberry Pi 3 Model B+ board yet. If you own a Raspberry Pi 3 Model B+, can you please benchmark (as per the instructions mentioned in TrueBench website) and submit me your results please. I need this for research standpoint.

I have developed a new CPU benchmarking system titled: TrueBench
It is meant for product architects, OEM product manufacturers, CEOs/CTOs to evaluate a specific hardware platform (such as an ARM/Intel/MIPS/etc. CPU/SoC) for design and manufacture of a commercial product.

NOTE:
For this purpose alone I do not want to buy a Pi3 B+ since it is not a question about money/price. I do not want eWaste. I do not like buying something and then tossing it since it is outdated without being purposefully used to its fullest potential. Hope you understand.

http://truebench.the-toffee-project.org

NOTE:
TrueBench is strictly a single core, single thread (or single dimension) benchmarking system. The objective is to benchmark the CPU<>MEMORY (RAM+/CACHE) data-path efficiency.

Thank you, Kiran (Author: The Linux Channel - Youtube Channel)

Since this appears to be a commercial effort, you really should buy your own board to test. If you don't want to keep it afterwards, you can donate to some person or organization. What you're asking for is people's *time*, and that is worth considerably more than the cost of the Pi3B+.

This is not a commercial stuff. It is a open source website ".org".

Running now.

I can test the 3B, 2B v1.1 (not the 1.2 though).

And if you compiled for V6 pi1's then the Zero's, A+ (256) and B+ too. And probably an old B and old A but you'll not gain anything. Zero and ZeroW would be the main ones at the moment.

[bensimmo]

Also if you compiled a 64 bit V8 version then I'm sure someone should be able to run that.
(Maybe it should be noted the Pi are all in 32bit v7 on the charts ?)

RPi3 B+, not overclocked, on-demand CPU governor, running gentoo-on-rpi3-64bit (same system as Gavinmc42, above), but:

• no desktop running, benchmark was invoked from a console prompt (see tail of post for details);
• the RPi3 B+ has a decent heatsink (with third-party thermal compound) attached; and
• I compiled your program (truebench.c) with gcc-6.4.0, no optimizations (just "gcc -o truebench truebench.c && ./truebench")

Results:

Code: Select all

The program seems to be having problems parsing /proc/cpuinfo on 64-bit RPi3 systems (not all the fields such as revision show the same as when booted in 32 bit mode), here's a raw dump from my RPi3 B+:

PS: to switch temporarily to a console login (removing the Xfce4 desktop which consumes some cpu time to maintain), boot the gentoo-on-rpi3-64bit image, open a terminal, become root, then:

Code: Select all

pi64 ~ # rc-update del xdm default
pi64 ~ # reboot

Once it reboots, log in at the textual console, and run the benchmark. Once done, to get your desktop back, just:

Code: Select all

pi64 ~ # rc-update add xdm default
pi64 ~ # rc-service xdm start

[bensimmo]

I've started it on an A+, oddly none of the Zero's would boot the images properly.

See you in a few hours

A+ /256 (measured at the standard 700MHz, they do happily run at 1GHz like the Zero though)

Another to the 64biters above, the Pi benchmark doesn't report anything for the platform, just the time and the dummy.

Given it ran, I guess the code is compiled for the old v6 platform even though the Pi2+ can use v7 code and neon in 32bit.

Not that I've looked to see if the code needs, wants or would benefit from it.
But if it was a business platform and they would probably use v7 optimised code and for go the need to run it on anything older.

Anyone checked to see what the code is doing ?

Yes, I did a quick hygiene check before compiling it: it basically calls the following function (once), inside a timer, then prints the results:

Code: Select all

#define MAXBYTES 1000000
#define ITERATIONS 1000000
char dummy_result=0;
char dummy_result2=0;
char dummy_buf[MAXBYTES];
char dummy_buf2[MAXBYTES];
void dummy_load()
{	int i;
	for(i=0;i<ITERATIONS;i++)
	{	memset(dummy_buf2, i, MAXBYTES);
		memcpy(dummy_buf, dummy_buf2, MAXBYTES);
	}
	dummy_result=dummy_buf[60];
	dummy_result2=dummy_buf2[60];
}

[Gavinmc42]

My PiI3B+ had no extra heatsink and was in Official case/power supply, room temp about 24C.

I did the objdump, Aarch64 code is much smaller than Intel Core Duo code
How much is compiler and how much is architecture and memory speed?
It reported the Intel Core Duo correctly, no info for the Pi3B+.

CPU clock and temp before and after might be useful?

Sorry I was been away. Thanks a lot everyone

I later publish the same in TrueBench.

BTW, I once shot a video episode on : CPU Load Process (i.e process with no threads) vs Threads (Process with multiple threads)
https://www.youtube.com/watch?v=uezu2OfQlaM

Hope this will give some insight why I did TrueBench that way. In case if you are curious.
And in this video I explained why I did the code that way.

Thank you, everyone. Once again !!
