I realize this is a moot point, considering Intel is no longer shipping Joules. But there are two prototypes in a lab... and I was wondering if this processor is susceptible.
Thanks for reaching out. We are looking into your question, as soon as we have information available we will get back to you. Thank you for your patience.
Following up with your question, the Intel Atom® processor that is part of the Intel® Joule™ 570x products is not impacted by the Meltdown/Spectre vulnerabilities.
