Complete List Of CPUs Vulnerable To Meltdown / Spectre Rev. 8.0

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 On The Meltdown + Spectre CPU Flaws! 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.

What Are 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 On The Meltdown + Spectre CPU Flaws!

 

The CPUs Vulnerable To Meltdown / Spectre Updated!

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 8.0, we believe we have covered all of the affected AMD, Apple, ARM, IBM, Intel and VIA CPUs. But we will add more CPUs (and devices) 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.

 

Vulnerable CPUs By The Numbers Updated!

Meltdown + Spectre Reading Suggestions

 

The AMD Server CPUs Vulnerable To Spectre

Affected Variants : AMD CPUs are affected by both Variants 1 and 2 of the speculative execution CPU bug. Colloquially, many people refer to them as Spectre 1 and Spectre 2.

    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.

    1. Dr. Adrian Wong

      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.

    What’s the source for this list? How do you know it is accurate? The processor manufacturers don’t even provide this level of detail?l.

    1. Dr. Adrian Wong

      No, they don’t provide this level of detail. If they did, we wouldn’t need to come up with this list.

      We sourced them from the documents and other information released by the manufacturers. The same information other people can verify on their own.

      They are accurate. In fact, we have been overly conservative, which is why we keep adding more CPUs over time.
