Hi everyone,
I’m considering buying a UUGear Vivid Unit for a network testing project, but I haven’t been able to find clear information about the Ethernet port speed.
Does anyone know if the built-in RJ45 port supports Gigabit Ethernet (10/100/1000 Mbps)?
More importantly, has anyone tested the actual Ethernet throughput using iperf3 or a similar tool? I need the device to be capable of around 900+ Mbps TCP throughput, since I plan to use it for wired Internet speed tests.
If anyone owns a Vivid Unit and could run an iperf3 test, that would be extremely helpful.
Thanks!
Yes, the built-in RJ45 port on Vivid Unit supports Gigabit Ethernet (10/100/1000 Mbps). The hardware uses an RTL8211E Gigabit Ethernet PHY connected to the RK3399 via RGMII.
We also ran an iperf3 test specifically for your question.
Test setup
- Vivid Unit ↔ Gigabit router/switch ↔ Raspberry Pi
- Both devices connected via wired Ethernet
- Both Ethernet links negotiated at 1000 Mbps, full duplex
- Wi-Fi disabled on both devices during the test
- Single TCP stream
- 30-second test
- Standard MTU 1500
Vivid Unit → Raspberry Pi
iperf3 -c 192.168.1.42 -t 30 0.00-30.00 sec 3.29 GBytes 942 Mbits/sec 0 sender 0.00-30.00 sec 3.29 GBytes 941 Mbits/sec receiver
Raspberry Pi → Vivid Unit
iperf3 -c 192.168.1.42 -t 30 -R 0.00-30.00 sec 3.29 GBytes 942 Mbits/sec 0 sender 0.00-30.00 sec 3.29 GBytes 941 Mbits/sec receiver
So in our test setup, Vivid Unit sustained approximately 941 Mbps TCP throughput in both directions using a single TCP connection, which is essentially full practical throughput for a 1 Gigabit Ethernet link.
Therefore, for your requirement of around 900+ Mbps wired TCP throughput, Vivid Unit should be capable of meeting it.
