RockPiS Benchmarks

#1

Using http://roylongbottom.org.uk/Raspberry%20Pi%20Benchmarks.htm

I will just run one test of each which will include Rays original Pi3 Bench but think that might be original Pi3 and not the B+ but will route one out later.

wget http://www.roylongbottom.org.uk/Rpi3-64-Bit-Benchmarks.tar.gz
tar -zxvf Rpi3-64-Bit-Benchmarks.tar.gz
cd Rpi3-64-Bit-Benchmarks

Compile & run first test.

gcc whets.c cpuidc.c -lm -lrt -O3 -mcpu=cortex-a35+crc+crypto -mtune=-mcpu=cortex-a35 -o whetstonePi64
./whetstonePi64

Yeah I was hoping maybe others would provide others as the above is a standard Pi bench that has been much used.
Mr Kaiser has a great set of benchmarks but been wondering what CFLAGS to use even if they should.
So would like any input but basically the A35 is very comparable with a A53 when running at 1.3Ghz.

So would be great if he has or anyone else would benchmark and if anyone is going to OC past 1.3Ghz.

#5

@igorp

Someone posted about temps and just thought I would have a look and even if I could push to 1.4ghz as have seen Mediatek @ 1.5ghz, but hey.

The thermal_zone in the dtb are all over the place.

I will let you take a look but no-one is getting 1.3ghz as this just throttles @55’c right back down to 1ghz.

The trips are working but seem to be dropping to the wrong clock speeds and wow trip-point-1/soc-crit are crazy values.
They are just overridden by rockchip,high-temp in the radxa dtb.

I always get confused at the order of trip and clock point as otherwise would of posted a dts with much better settings.
What we have is very confused… :slight_smile:

I think the above benches likely need to be ignored as bet it was throttling.

#6

I do not know why but Radxa’s engineers decided to use “rk3308k.dtsi” as the base for ROCK Pi S device tree while I do believe it was meant for a different variant of the SoC (RK3308K).

I mentioned it last year:

Since the first Armbian release for ROCK Pi S the base DTS has been switched to “rk3308.dtsi” with 70/85/115 ºC trip/crit points.
Here are the sbc-bench results without throttling: http://ix.io/1XKY

All in all it was never meant to be a performance SoC being severely limited by memory interface:

  • 16-bit RAM bus
  • 589MHz(*2) DDR clock in Rockchip’s DDR loader

Nonetheless IMHO it is doing well and has a great benefit of using ~0.4W idle while being connected to the network and ~0.2W without it.

What confused me was the rockchip,high-temp = < 0x11170 >; rockchip,high-temp-max-volt = <x112a88 >;

	};

1392000000 seems pretty stable dunno just got a feeling maybe the volts are safely high so didn’t increase.

I was just wondering if stable how A35 vs A53 compares with the 1.4Ghz of the Pi3A+

Think I will run those benches again just to see if any different with both a slight OC & maybe no thermal throttling but don’t know if it was or not last time but 55 seems very low.
It could do with a Kaiser treatment :slight_smile:

@piter75 PS 16bit ram bus? Its the same as the A53?

https://www.anandtech.com/show/9769/arm-announces-cortex-a35

It’s especially on memory benchmarks where the A35 will shine compared to the A7: The A35 adopts a lot of the Cortex A53’s memory architecture. On the L1 memory system of which A35 can have configurable 8 to 64KB of instruction and data caches we now see use of multi-stream automatic data prefetching and automatic write stream detection. The L2 memory system (configurable from 128KB to 1MB) has seen increased buffering capacity and resource sharing while improving write stream efficiency and introducting coherency optimizations to reduce contention.

The NEON/FP pipeline has seen the biggest advancements, besides improved store performance the new units now add fully pipelined double precision multiply capability. The pipeline has also seen improvements in terms of area efficiency, part of the reason enabling the A35 to be smaller than the A53.

I am not seeing it as a performance SoC but do see it as a Pi3A+ alternative with my interest in voiceAI.
I have a lot of FFT routines that the Neon improvements should be great for.

Been running for a fair old while now and seems to of settled at approx 64’c with a load of just above 3 with stress just running x3 cores at max (What I say is a good average heavy continuous load).
Temp has dropped suddenly in the UK after the storms and not particularly warm at the moment.

What is 589MHz dram? Strange speed.

It’s not the architecture’s but SoC’s design property: RK3308 uses 16-bit hardware interface width while RK3326 and PX30 use 32-bit - all of them being A35 :wink:

I don’t know why Rockchip has chosen this exact value but I suppose it may have to do with wifi interference avoidance similarly as they did with LPDDR4 speeds in rk3399:

  1. 416MHz and 856MHz is the frequency avoid disturb wifi 2.4GHz
#10

Just confused as for DDR3 it just seems a really weird choice as a slight OC on 800Mhz makes some sort of sense, for the above.

590Mhz does seem really weird as what is it, if you get what I mean?!?

DDR3-1066 133 MHz 7.5 ns 533 MHz with quite a considerable OC?
Prob is and also just added 56Mhz.

#11

Even 1488000 seems really steady with no volt increase that maybe the current image has very safe voltages but maybe a tad excessive and could run far leaner.

I stepped back to 1.4Ghz and did some phoronix-test-suite benchmarks.

The above had a 3+ below has a Zero.
