Yes, I love flashing BIOS...
edit nvm, Microcode can get updated via system updates.

#3AMD Ryzen 5000 Series Processors with Radeon Graphics
Does this mean Ryzen CPUs without integrated graphics are fine?
Re: Zenbleed
#4Relevant snippet:
This technique is CVE-2023-20593 and it works on all Zen 2 class processors, which includes at least the following products:
AMD Ryzen 3000 Series Processors
AMD Ryzen PRO 3000 Series Processors
AMD Ryzen Threadripper 3000 Series Processors
AMD Ryzen 4000 Series Processors with Radeon Graphics
AMD Ryzen PRO 4000 Series Processors
AMD Ryzen 5000 Series Processors with Radeon Graphics
AMD Ryzen 7020 Series Processors with Radeon Graphics
AMD EPYC “Rome” ProcessorsRe: Zenbleed

No, it's all Zen 2 CPUs, which include both desktop CPUs (with or without integrated graphics, laptop CPUs, and server CPUs. The reason why the product list is so confusing is that AMD reuses architectures across generations. You'd think that all ryzen 5000 series CPUs have the same microarchitecture, but they don't). It's much easier to consult this list instead: https://en.wikipedia.org/wiki/Zen_2#Products

To be fair, flashing the bios isn't nearly as bad on most modern systems.
Put the file on a USB drive, plug it in, restart and go into the bios, look for the flashing utility, select the file, done. As long as the machine is on a UPS in case of disaster, everything's accounted for.

Microcode updates haven't been managed in-BIOS for over a decade now. If you use Linux, you'll usually see them released as some package like "intel-microcode" or "amd-microcode".
Even EFI updates rarely are very intrusive or dangerous, and can also be handled by the Operating System via an update.

From my experience: Better have a > 32gig USB Flash drive, everything else doesn't work (MSI) and I don't have an UPS so it's always quite an exciting experience. Especially since Motherboard Manifactures save almost a whole dollar by not having a display ouputting anything. So it's blinkenlights and hope for the best

No this means AMD's numbering scheme is intentionally obtuse. This has nothing to do with graphics, but with the CPU core, Zen 2.
