The 6i instances are beating all amd and generally-available graviton instances in raw performance and performance-per-dollar on my workloads. I don’t think you’ll be well-served carrying this mental bias around. Better to actually try it and find out.

If you’re going to compare the paper performance of an unreleased machine to a 3-year-old Intel machine then yeah probably the former will win.

I didn't mean to pick sides, or suggest anyone picks graviton by default. I meant to comment on how the communication around these new architectures by AWS has shifted, and what - I think - it signals about Intel's current and future market position with AWS.

For reference, my stuff runs on Heroku, I'm clearly not that concerned about price/performance ;)

I can confirm that:

Build time of a Linux 5.13.11 kernel with `make defconfig all`

c6i.32xlarge: 24.871411s

m6a.48xlarge: 27.622526s

Build time of a Linux 5.13.11 kernel with `make allmodconfig all`

c6i.32xlarge: 183.775255s

m6a.48xlarge: 205.326048s

128-way Intel seems to consistently beat 196-way AMD for software builds.

(Correction: 192-way AMD.)
