The Complete List Of CPUs Vulnerable To Meltdown / Spectre Rev. 4.0

The Complete List Of CPUs Affected By Meltdown + Spectre

The speculative execution CPU bug that literally kneecapped Intel, also affects many AMD and ARM processors. This means BILLIONS of CPUs around the world, including those powering smartphones, are affected by Meltdown and/or Spectre.

Our article Everything We Know About The Intel, AMD & ARM CPU Bug! summarises the key details of  the speculative execution bug, and what we can do about it. This guide is to help those who want a full list of affected CPUs. Because we intend this to be an exhaustive list, we split it into multiple sections.

Updated @ 2018-01-14 : Added 416 Intel server CPUs, 8 Intel desktop CPUs, and 29 Intel mobile CPUs to the lists of vulnerable CPUs. Added a new list of 51 Intel mobile SoCs.

Updated @ 2018-01-12 : Added 71 AMD server CPUs, 71 AMD desktop CPUs, 29 AMD mobile CPUs and 3 AMD server SoCs based on a vulnerable ARM CPU. Also added a table summarising the number of vulnerable processors.

Updated @ 2018-01-11 : Added 18 Intel desktop CPUs and 165 Intel server / workstation CPUs. Also added a list of vulnerable Apple iOS devices, and expanded the list of vulnerable mobile SoCs used by smartphones.

What Is Meltdown And Spectre?

Meltdown and Spectre are two exploits that take advantage of three variants of the speculative execution bug that affects billions of CPUs around the world.

The Complete List Of CPUs Affected By Meltdown / Spectre

The Spectre exploit targeted Variants 1 and 2, while the Meltdown exploit targets Variant 3, of the CPU bug.

For more information on the speculative execution bug, and the Meltdown / Spectre exploits, please read Everything We Know About The Intel, AMD & ARM CPU Bug!

 

The CPUs Vulnerable To Meltdown / Spectre

For easy reference, we divided the affected CPUs by Company (arranged ALPHABETICALLY – no conspiracy, we promise), and subsequently by Segment (Workstation / Desktop / Mobile), or affected variants.

As of Revision 4.0, we believe we have covered all of the affected AMD, Apple, ARM and Intel CP:Us. But we will add more CPUs as and when they’re noted to be vulnerable to the Meltdown and Spectre exploits.

Note : It’s arguable that all CPUs that uses speculative execution to any degree are potentially vulnerable to Meltdown or Spectre or a future exploit. We will only focus on CPUs that are confirmed to be vulnerable to Meltdown or Spectre.

    Thank you for making this list, it’s very helpful, and much appreciated.

    I’m interested to know if the Core 2 Duo range of CPUs is affected.

      It’s our pleasure. We will be adding more CPUs to the list shortly, and will keep updating it when we get more details.

      Right now, no, the Core 2 Duo range of CPUs are not affected.
