    I spent nearly an hour spinning up Linodes the other day just to get an Epyc processor. Nothing I personally rely on will ever touch Intel processors. Typing this from my AMD 1950x Threadripper. AMD from here on out for the foreseeable future.

    which Linode plans ? and which Linode data center regions ? You're more likely to get them for newer data center regions that older ones.

    Atlanta. I found that if you do not use Dedicated you are far less likely to get AMD. Dedicated is much more consistent.

    Ended up with

    Code:

    Yeah Linode dedicated plans are more likely to get higher end cpus :)
