Intel Punts Out List Of CPUs That Will NOT Get Fixes For Meltdown & Spectre

Intel released an update to the Meltdown and Spectre mitigation guide which is a PDF document that Intel published in February. The file contains information on the status of microcode updates for each of Intel’s CPU models released in the past years. And in this update is the news that the following CPU models will not get updates to mitigate the Meltdown and Spectre CPU flaws:

  • Bloomfield
  • Bloomfield Xeon
  • Clarksfield
  • Gulftown
  • Harpertown Xeon C0
  • Harpertown Xeon E0
  • Jasper Forest
  • Penryn/QC
  • SoFIA 3GR
  • Wolfdale C0
  • Wolfdale M0
  • Wolfdale E0
  • Wolfdale R0
  • Wolfdale Xeon C0
  • Wolfdale Xeon E0
  • Yorkfield
  • Yorkfield Xeon

Using my friend Google, most of these CPUs are a decade or more old. Therefore it’s understandable that they won’t be getting updates to fix these flaws. However if you’re still using one of these CPUs, consider this to be your incentive to move onto something much newer.
