If Epyc CPUs aren't available, then it isn't apples to apples. A customer doesn't care about nm. They care about what's available. The apples to apples comparison is The best x86 available vs the best ARM available.

You can buy Epyc v2 CPUs from Newegg. It's just that AWS doesn't have instance types that use them.

    Yeah, but not second generation Epyc. Their blog says the instance type will be called C5a: https://aws.amazon.com/blogs/aws/in-the-works-new-amd-powered-compute-optimized-ec2-instances-c5a-c5ad/ https://aws.amazon.com/blogs/aws/in-the-works-new-amd-powere... Right now, according to the official C5a page, they are "coming soon".

  Those are AMD Epyc 1 CPU's, which are built using a 14nm process at GlobalFoundries. Epyc 2 CPU's, which are significantly faster, are announced to be available at AWS in future, but aren't yet.

    Thanks for the info. That's something to keep in the radar.

Graviton2 based EC2 instances aren't generally available yet either. To quote the product page [1]: > Amazon EC2 M6g instances are currently in preview and will be generally available soon. [1]: https://aws.amazon.com/ec2/instance-types/m6/ https://aws.amazon.com/ec2/instance-types/m6/
