You can spin up test cloud servers and extract CPU flags with the help of this little script using
csplit.
cat /proc/cpuinfo | csplit -z - '/processor/' '{*}'
diff xx0*
grep flags xx01 | cut -d ':' -f 2 | xargs -n1 echo | sort > flags.txt
By comparing the results we can definitely say that:
- Performance1 and performance2 cloud servers are running on the same hardware.
- New performance cloud servers are hosted on Intel CPU.
- The standard (next generation) series are being hosted on AMD CPU.
The CPU flags for comparison.
