Initial Benchmarks Of The Spectre "SWAPGS" Mitigation Performance Impact

[CochainComplex]

Ahh, the answer to what is Seven times Nine! (which is also weirdly appropriate for spectre!)

oh yeah ...seven of nine

[BaumKuchen]

I would like to see pre S&M performace and performance with applying all the patches.

Getting an AMD CPU doesn't sound too shabby right now.

At least with Zen 2, no firmware update needed for Spectre and Spectre V4 fixed in hardware... and like else AMD not affected by Meltdown, Foreshadow, Spoller, Lazy FPU, MDS...

By their own EPYC Horizon live presentation that i am watching right now now https://www.youtube.com/watch?v=9Jn9NREaSvc

Atom has been out-of-order since Silvermont in 2013.

I believe it's the speculative execution part that's required, not ooo. Even when linearly executed, the problem is a younger op executing before the older retires and flushes the bad path op, but it's not required to be out of order, or even supported.

Atom? ,-)

Correction: Every x86 based chip since the Pentium Pro. Once again, Itanium is immune.

Itanium could very well have it's own series of vulnerabilities. We are just not going to find out, ever.

Microsoft patched this vulnerability on July 9, a full fucking month ago. While most Linux distributions only got a hold of the patches today. It is well-known that attackers monitor Windows Updates and can deduce security vulnerabilites from patches, so they can then go attack unpatched Windows systems and other OSes.

This tells you everything you need to know about how much Microsoft "loves Linux", and how much Intel cares about security.
