It is common to see manufacturers of low-end tablets and pc's buying cpu's from Intel that only have SSE2-SSE4.1+AES+RDRAND enabled. I encounter them regularly in low-end netbooks. The cpu's probably have higher ISAs, they just are not enabled. Intel will also de-clock or slow down the cpu for the price point. I was talking to David Johnson, who designed Intel's RDRAND circuit. He told me intel can tune about 100 different parameters to vary cpu features and speeds for a particular price point. > You can look in /proc/cpuinfo to see the flags, or install "cpuid" to > get very detailed information.

Until I got the message I hadn't thought about anything related to AVX. The only reason I got the message was I'm following lessons in a Python book to refresh my python knowledge for future use at work, and the book was using pygame as an example of how to import modules. I'm running an AMD Ryzen 9 5950X 16-Core which I installed 18 months or so ago. regards, Steve -- ___ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org 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/users@lists.fedoraproject.org Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue OpenPGP_0x594338B1DE179AB2.asc Description: OpenPGP public key OpenPGP_signature.asc Description: OpenPGP digital signature -- ___ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org 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/users@lists.fedoraproject.org Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
