Because this post is quite long and with too many details, I’ve used a TOC so you can browse better.

1. Intro

Today I’m really happy that I’ve received the new Nanopi R5S from FriendlyElec to test it. 1.5 year ago I was able to test the Nanopi R4S and I’ve written two posts, with the last one here.

You can’t really do a 1-to-1 comparison between the two brothers, because the younger one comes with new features that the older brother lacks, but I’ll write more about that next.

2. The SBC

The NanoPi-R5S can be bought as a PCB only or you can also buy the black aluminum case as an extra. The quality of the case is very good and it’s made especially for the R5S. The fit is tight and this time I was really excited when I’ve seen the antenna hole above the USB power port. In my last post for the R4S benchmark here I had to drill my own hole on the case to fit the USB-to-UART adapter in order to get the debug console.

2.1 SBC - PCB

The PCB of the R5S is quite populated with several ICs. This is the bottom side.

NanoPi-R5S NanoPi-R5S PCB

And this is the top side.

NanoPi-R5S NanoPi-R5S top side

On the bottom side you can see the 8GB eMMC and the PCIe2.1 M.2 connector for the nvme, which is 1x lane. The theoretical bandwidth of x1 lane for the 2.1 PCIe is 500 MB/sec, which means you don’t really have to buy and expensive nvme to populate the slot.

On the top side you can see the 2GB RAM, the 3x network PHYs under the ports, the SoC which comes with a silicon thermal pad and the RK809 PMIC.

There are also 2x USB 3.0 ports, an SD card holder and between the SD card the USB there’s an expansion connector for UART/SPI/PWM. The debug uart (console) is next to the LAN2 2.5G port. This is useful to solder a pinheader and connect a USB-to-UART module to get the output for debugging.

2.2 SBC - UART mod

It’s easy to get the debug console output. All you have to do is to solder a pin-header and then connect a USB-to-UART module.

The default baudrate for the UART is 1.5Mbps, therefore many modules won’t work. I’ve used a module with the FTDI FT232RL chipset.

This is how it looks like with the UART mod.

NanoPi-R5S UART mode

And this is how it looks assembled in the case.

3. NanoPi R5S specs

The main specs of the NanoPi R5S are listed here, but I’ll mention the ones that I consider the most important.

Back to TOC

3.1 Specs - OS

The OS that the R5S came with in the eMMC is a branch of the OpenWrt, which is named FriendlyWrt. This branch includes all the needed drivers and it has the proper device-tree to support the SoC.

This is the uname result:

1

Linux FriendlyWrt 5.10.66 #1 SMP PREEMPT Wed May 18 17:58:14 CST 2022 aarch64 GNU/Linux

Therefore the kernel is based on Linux 5.10.66.

Back to TOC

3.2 Specs - SoC

The SoC is the Rockchip RK3568B2 which is a Quad Core Cortex-A55 CPU. On idle the FriendlyWrt reports:

root@FriendlyWrt:~# cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_max_freq
1992000
1992000
1992000
1992000

Therefore, all the cores are running at almost 2GHz.

Back to TOC

3.3 Specs - Network interfaces

Nanopi R5S, has 3 HW network interfaces:

  • eth0, it’s the SoC’s native 1Gbps network adapter which is mapped to WAN port
  • eth1, it’s the first 2.5Gbps PHY connected on the PCIe bus
  • eth2, it’s the second 2.5Gbps PHY connected on the PCIe bus

These are the PCIe devices:

0001:11:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller (rev 05)

So, the 2.5Gbps interfaces are based on the RTL8125.

Here, except the eth0-2 we can see also other virtual interfaces used from FriendlyWrt to handle the WAN and LAN interconnections.

  • erspan0, is a virtual interface used for port mirroring.
  • gre0 and gretap0, are the GRE tunnel. GRE are IP-over-IP tunnels, which can encapsulate IPv4/IPv6 and unicast/multicast traffic.
  • br-lan, is the bridge network for LAN and WAN.

Finally, this is how IRQ are mapped for each interface to each core.

As you can see eth0 IRQ is mapped on CPU3 and eth1-eth2 on CPU1-2.

3.4 Specs - Storage

There is an internal 8GB eMMC mapped in mmcblk2 where the OS was installed and an SD card slot mapped to mmcblk0. I’ve also installed a Crucial P2 1TB nvme.

This is how the nvme SSD drive fits on the motherboard. The nvme installed on the board

This nvme drive is much faster compared to the 1x lave PCIe2.1 interface, so I don’t expect to get the full bandwidth, but it should be close to the theoretical 500 MB/sec.

The nvme drive is formatted as EXT4.

For the benchmark I’ve used hdparm and f3.

f3 - Fight Flash Fraud is another benchmarking tool. I’m not sure how accurate that is but I’ve used it in any case. Since f3 is not available on FriendlyWrt repos, I’ve cross-build it statically and then scp the fread and fwrite executables to the NanoPi-R5S. Have in mind that FriendlyWrt is build with musl therefore you shouldn’t build it as a dynamic ELF on your x86_64 host.

To build f3 on my host I’ve just used these commands:

Of course you need to point to the proper path of your aarch64 toolchain to build it. Finally, I’ve copied the files in the NanoPi-R5S.

eMMC

The results for the eMMC are:

root@FriendlyWrt:~# hdparm -tT /dev/mmcblk2

/dev/mmcblk2:
 Timing cached reads:   2036 MB in  2.00 seconds = 1017.76 MB/sec
 Timing buffered disk reads: 488 MB in  3.01 seconds = 162.22 MB/sec

Therefore, you can expect ~160MB/sec reads from the eMMC, which I personally consider more than enough for my use case.

SD

 Timing buffered disk reads: 1168 MB in  3.00 seconds = 388.92 MB/sec

The results are a far less from the theoretical advertised read speed of the drive which is 2400MB/sec. From other reviews of the drive though I’ve seen that it actually achieve 2100MB/sec read speeds, see the here for reference. But as I’ve mentioned the actual theoretical limit of the 1z PCIe is 500 MB/sec. Therefore, the actual speed is 25% less than than the maximum theoretical speed.

4.1.3 Benchmarks - Storage - f3 benchmarks

The f3 bench mark is to be considered a similar to real-life benchmark, because the CPU needs to perform calculations while writting and reading the data. Well, again it depends the use case, but I like to consider this as the worst case real-scenario.

4.2 Benchmarks - Networking

This is a TL;DR table with all the results. If you want to see more details for each test then keep scrolling to get a more deep dive.

  Test case 1 (Gbits/sec) Test case 2 (Gbits/sec) Test case 3 (Gbits/sec)
R5S -> M1 (CAT.6a) 1.49 TBD TBD
M1 -> R5S (CAT.6a) 2.14 TBD TBD
R5S <-> M1 (CAT.6a) 1.37 (TX) / 159 (RX) TBD TBD
R5S -> M1 (CAT.7) 1.49 TBD TBD
M1 -> R5S (CAT.7) 2.14 TBD TBD
R5S <-> M1 (CAT.7) 1.37 (TX) / 159 (RX) TBD TBD

The 3 different test cases are described below.

Testing a single 2.5G port

This is the first test case:

In the above diagram you can see that the Macbook Air M1 is connected via the USB-C to 2.5G ethernet adapter to the 2.5G LAN2 port of the NanoPi-R5S.

I’ll run this test with 2 different cables:

  • 20cm CAT.6a rated for 500MHz
  • 100cm CAT.7 cable rated for 600MHz

The reason for using two different cables is to check if the different cable category affects the actual bandwidth that the R5S can provide.

Test case 2 - 2.5G to 2.5G port

This is the second test case diagram:

In this case, I’ll test the interconnection between the 2.5G ports using two different external hosts.

This test is not done yet, as I need to buy a second 2.5G USB-C to ethernet interface.

Test case 3 - All ports

This is the second test case diagram:

In this case, I’ll test all the ports at the same time, which pretty much emulated a router usage

This test is not done yet, as I need to buy a second 2.5G USB-C to ethernet interface.

4.2.1 Benchmarks - Networking - Test case 1 - CAT6A

This test is performed with a CAT.6A patch cable of 20cm, which is characterized for 500MHz.

4.2.1.3 Benchmarks - Networking - Test case 1 - CAT6A - R5S<->M1

The second test is running for 120 secs, 2x parallel streams and in bidirectional mode.

Bidirectional mode means that the Mac M1 with the USB-C dongle will send data to the NanoPi R5S and then the opposite in full-duplex mode. This is the worst of the worsts case scenario you can get.

Host Command
Mac M1 w/ USB-C 2.5G iperf -s
NanoPi R5S (LAN2) iperf3 -c 192.168.2.20 -t 120 -d -P 2 –bidir

4.2.1.4 Benchmarks - Networking - Test case 1 - CAT6A - packet generation capabilities - M1->R5S

This benchmark was proposed from tkaiser in order to check the packet generation capabilities which would indicate the package processing speed if the device was used as a firewall. You can read more about it here

In the first test the M1 will be the sender

Host Command
Mac M1 w/ USB-C 2.5G iperf -s
NanoPi R5S (LAN2) iperf3 -u -c 192.168.2.20 -t 120 -R -O 5 -f m -b 2500M –length {size}

Notice the -R in the client command, which means reverse, so the M1 will be the sender/client.

This is the table with the results of the various sizes.

4.2.1.4 Benchmarks - Networking - Test case 1 - CAT6A - packet generation capabilities - R5S->M1

Read the test description from above In this test the R5S will be the sender.

Host Command
Mac M1 w/ USB-C 2.5G iperf -s
NanoPi R5S (LAN2) iperf3 -u -c 192.168.2.20 -t 120 -O 5 -f m -b 2500M –length {size}

This is the table with the results of the various sizes.

1500 321 Mbits/sec 0.000 ms 320 Mbits/sec 0.037 ms

From the above table and comparing with the previous table where the sender is the M1, it’s obvious that the RK3568 does suffer when it comes to packet generation capabilities. At least compare to the M1 SoC, which is not really a fair comparison.

4.2.2.2 Benchmarks - Networking - Test case 1 - CAT7 - M1->R5S


The second test is running for 120 secs, 2x parallel streams and in reverse mode.




  
Reverse mode means that the Mac M1 with the USB-C dongle will send data to the NanoPi R5S.

As you can see, the reverse mode is much faster and achieves 2.14 Gbits/sec!



4.2.2.3 Benchmarks - Networking - Test case 1 - CAT7 - R5S<->M1


The second test is running for 120 secs, 2x parallel streams and in bidirectional mode.




  
Bidirectional mode means that the Mac M1 with the USB-C dongle will send data to the NanoPi R5S
and then the opposite in full-duplex mode. This is the worst of the worsts case scenario you can get.

5. Conclusions


Well, personally I’m excited with the NanoPi-R5S. This is what you get for $60 today (+$16 for the case).
2x 2.5Gbps ports and a Quad core running all cores at 2GHz. For me, this makes a great router if you want
to upgrade to 2.5G. Also the fact that it comes with an OS that you can do pretty much whatever you like
it’s also nice. You can even use the nvme M.2 slot to install an SSD and use it as your local network
storage.



Also, FriendlyWRT it’s not the only OS you can get. You can choose also between Android and Ubuntu and
a docker ready image. This means that you can use the NanoPi-R5S for many different use-cases. For example,
it could also serve as a k3s node (I suggeset the 4GB RAM for that). There are really so much things that
you can do. Especially, since I’m running my own K3S cluster with 1x Jetson nano as the master and 3x
RPi-8GB nodes, the NanoPi-R5S really rings a bell to me that it would be a great K3S node.



My personal opinion, according to my current testsm is that this is the best SBC from FriendlyElec so far.
The performance/price ratio is great, especially considering the high prices of other alternatives right now
and the lack of SBC in the market because of the COVID.



Unfortunately, I need to leave for a couple of months and therefore I won’t be able to play around more
with the NanoPi-R5S, but when I’m back I would like to test it also in a K3S cluster. I mean for the price
is a no brainer. You can build a 2.5G K3S cluster at your home. Just wow…



I’ll be back with more tests in the future.



Have fun!
