So far the word is the microcode fix causes negligible performance impact, but using the MSR fix causes 5-15% loss. In my own testing on EPYC hardware, microcode made no noticable difference to my workloads and benchmarks. Same as random noise in results.

I’m just going to pretend I didn’t buy any AMD surface laptops.
Is there any information on the performance impact of the microcode fix or is it too early for that?

Well
that’s not great
Yikes.
Welp. Thankfully my current AMD desktop PC will be the last one I’ll be using in my whole lifetime – RISC-V 4va. :^)
Why is it that every time there’s drama about hardware, its something I own?
Click bait. Alleady fixed on every platform
Why are users on Linux stating the opposite then?
Misled by stupid clickbait? I’m on linux, it’s fixed by microcode update in linux-firmware and kernel mitigation, commit says july 24 22:07:56
So it was patched literally 2 days ago.
You think everyone updates their kernel off source that quickly? This vulnerability is absolutely still out in the wild.
“Could take many months to fix” is bullshit
How come branch prediction seems so vulnerable to exploits? Both spectre and meltdown were also caused by branch prediction not working quite right.
Makes me glad I’m using an ancient CPU from before the vulnerability.
