AMD chips are reportedly susceptible to Spectre, so that's not going to help. From https://meltdownattack.com https://meltdownattack.com:
Almost every system is affected by Spectre: Desktops, Laptops, Cloud Servers, as well as Smartphones. More specifically, all modern processors capable of keeping many instructions in flight are potentially vulnerable. In particular, we have verified Spectre on Intel, AMD, and ARM processors.
- lawrenceyan 9y agoMeltdown, however, is the one that results in nontrivial performance degradation in order to patch. And Meltdown specifically only affects Intel processors.
- onedognight 9y agoMeltdown affects some ARM prcessors as well. https://developer.arm.com/support/security-update https://developer.arm.com/support/security-update
- lawrenceyan 9y agoMy response was in the context of privong stating that Intel and AMD were equivalently affected, when it is specifically Intel that suffers performance degradation in patching due to their unsafe usage of speculative execution.
- privong 9y agoI only said they were both affected by Spectre. But it wasn't clear if the OP was worried about performance issues or security issues, so it isn't clear on what basis they were suggesting that buying AMD is a solution.
- noselasd 9y agoAMD is not susceptible to Meltdown. So the issue is not inherent to the x86_64 architecture. Knowing that, can it be possible that Intel can patch their CPU via micro-code in a manner that does not affect performance to a great degree, and not require a software patch to solve the Meltdown attach ?
