I don't understand the throughput numbers given. 5.6GB/s for GCP and 9.6GB/s for AWS would be 44gbps and 76gbps respectively.

I don't don't know of any instances offering that kind of throughput.

I've personally validated GCP's statement that they offer 2gbps/core up to 16gbps. I can get 16gbps consistently between any two n1-standard-8 using iperf.

This generally makes network IO in GCP much cheaper.

I wouldn't read too much into it, it's clearly Gbps. The authors are just sloppy with capitalization. They also elsewhere talk about iperf having "128 kb" buffer which seems unlikely, and the throughput graph says "gb" where the text says "GB".

And then there's "iPerf" and "PING"...

If it were gbps then that's certainly weird. I consistently get way better network performance in GCP than in AWS.
