> Aren't the Zen3 instances still faster than Graviton 3?

Irrelevant.

The vast majority of applications running in the cloud are business applications that struggle to saturate the CPU and waste most of the CPU cycles idlying by in epoll/select loops. Unless you need HPC, you do not need the fastest CPU, either.

Don't like AWS/Graviton? Take your workload to the Oracle cloud and run it on Oracle ARM.

Don't like ARM? If your app is interpreted/JIT'd (e.g. Python/NodeJs) or byte code compiled (JVM), lift and shift it to the IBM cloud and run it on a POWER cloud instance – as long as IBM offers a price-performance ratio comparable to that of AWS/Graviton or you are willing to pay for it.

On that note being able to rent a 160 core machine for $1.6/hour on Oracles cloud service is really impressive. If you have an integer intensive workload (i tested SAT solving) the Ampere A1 machine Oracle rents out are really competitive.

I don't do HPC, just real time video encoding. It's never enough even with h264.
