The single core performance is remarkable given that Intel has always been very strong there. How is Linux compatibility in case of AMD these days? Intel is really good, if we ignore the need for blobs for their wireless cards. Everything just works, and it is energy efficient.

I can only speak for the first gen zen. There's a bug with most motherboards that cause a hard lockup every day or so. Changing the power state fixes the problem with an updated bios but disables boost. Thread: https://bugzilla.kernel.org/show_bug.cgi?id=196683 https://bugzilla.kernel.org/show_bug.cgi?id=196683

> How is Linux compatibility in case of AMD these days? You install linux on an AMD system and it runs. Its been that way for a decade. If you buy an AMD GPU and choose a wireless card with care then there really isn't anything to think about when using linux except maybe needing a firmware blob. AMD is one of the better vendors for linux compatibility. CPU, GPU, whatever. All has first class open source support. It isn't fun like the good old days when things went wrong and people had to learn about the internals of the system to make things run, fighting the hardware every step of the way. Kids these days will have no opportunity to learn how all this stuff hangs togther. It could be worse than the time everyone stopped having to learn assembly. We live in an age of moral decay.

Amd kept leaping ahead in single core while intel finally got their security mitigations in place. Although intel was ahead against zen+, it was not by as much as you imagine since a lot of the intels where tested with mitigation’s partially off by then (and then of course there is intel insistence on reviews being done with smt off which is cute since amd performs better on it too)

I had to add kernel parameters in the installer and bootloader for the computer to install and boot. Otherwise it doesn't even boot. Ryzen 5. An upgrade from kernel 4.x to 5.x only changed the required parameters, it still locks up on boot with no extra parameters. acpi=noirq pcie_aspm=off iommu=pt
