AMD: brief statement on Spectre/Windows Update issue
Earlier today we already posted news that some AMD platforms have issues with the new Microsoft Spectre and Meltdown patches. Some end-users ended up into systems not booting after Microsoft applied the patch.
AMD just send out a small statement on that, I'll just post that as -is:
-- AMD --
AMD is aware of an issue with some older generation processors following installation of a Microsoft security update that was published over the weekend. AMD and Microsoft have been working on an update to resolve the issue and expect it to begin rolling out again for these impacted shortly. Also, we wanted to make it clear this patch is to address GPZ Variant 1 (one of the variants of Spectre) and not GPZ Variant 3 (Meltdown).

Now it seems that m$ might not be the only one responsible for AMD systems not booting.

The important part I guess...
“AMD is aware of an issue with some older generation processors following installation of a Microsoft security update that was published over the weekend,” says an AMD spokesperson. “AMD and Microsoft have been working on an update to resolve the issue and expect it to begin rolling out again for those impacted shortly.”"

Exactly, everybody's working on fixes on all ends anyway. Like stated a couple of times, I too think in the next 2 weeks everything will be patched, from BIOS / microcode to OS updates to drivers to whatever.

It's not just servers and people running VMs affected. The performance impact, per MS, is dependent on processor architecture and Windows version. Skylake and newer are expected to see a negligible performance loss. Haswell and older will see a greater but varying degree of performance loss dependent on architecture and Windows version. Servers will be the most affected due to heavy I/O based workloads.
When someone says something like "up to 30%", the statement implies that the affect will vary between 0% and 30%. Most people just have an issue comprehending what "up to" actually means. Yes, the media does have a bad habit of stretching the truth or exaggerating depending on the subject, but at the same time, readers have a tendency to read what they want and not necessarily what's really there. I've been telling people since the news broke that the performance loss for most wouldn't be anywhere near as bad as they were worried about. Sadly, people kept seeing that "up to 30%" and ignored the rest of the facts.
