At best, we could come up with some estimates based on the stats from other sources that we might assume have a similar profile as Fedora. I'm not sure if that data exists anywhere, though. My main personal machine also lacks AVX2-capable hardware, so from a personal perspective, I'm not super keen on this change. I'm privileged enough to be able to upgrade my hardware if required, but I recognize that it's not a reasonable request for others. > > Fedora will use current CPUs more efficiently, increasing performance > > and reducing power consumption. > > I think we need to see some actual benchmarks demonstrating this.

It would be good to see some more specifics about what the benefit will be. That's the only way we can decide if it's worth the cost. -- Ben Cotton He / Him / His Fedora Program Manager Red Hat TZ=America/Indiana/Indianapolis _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx
