Benchmark test - direct vs usb-c adapter


Benchmark test

We connected the SIMBA 2.5 Gbps fibre broadband cable direct to the Belkin Connect USB-C to 2.5 Gb Ethernet Adapter and plug it into the USB-C 3.0 port on the Gigabyte AMD X570 Extreme motherboard. The results are tested against the same cable plugged directly onto the 2.5 GbE port on the same motherboard.

The results are as follow using app. You might be wondering why we tested it against a Malaysian server instead of a Singapore server. The reason is because Singapore server seems to be capping the bandwidth of speedtest originating from simba users. Most of the Singapore servers will throtlte the speed to max at around 1 Gbps giving you a skewed result. It would be best SIMBA host their own server.

Using nPerf, another application which test network speed, we did compare the difference between direct 2.5 GbE port connection versus via USB-C adapter.

We chose nPerf because it provided a less congested 10 Gbps public server for us to test against.

For both Speedtest and Nperf, we can see a consistent difference of around 200 Mbps between direct connection vs usb-c adapter.
