Is it too much to expect Intel and AMD not to ship chips with self-frying firmware?
Ues. They clock down laptop cpus after release so benchmarks look good
As for the security updates point, I am in a bit of a bind because my laptop is a 2019 model Thinkpad that I bought in 2020. Of course Lenovo stopped supporting it many years ago, so when I input the serial number I get this lovely message:
“This product is no longer being actively supported by development (End of Development Support) and no further software updates will be provided. Any software or support resources provided by Lenovo are made available “AS IS” and without warranties of any kind, express or implied. Products still covered under the Lenovo Limited Warranty will be covered for repair.”
Thank heavens I removed Windows and disabled secure boot, otherwise I would probably be locked out of my device by now due to expired secure boot keys.
Yes. You can’t expect perfection from humanity, you know.
Also, I believe Windows’s secure boot keys can be updated through Windows Update?
I wouldn’t know as I don’t use Windows. 
I do know that my MiniPC can’t use Secureboot because the vendor stopped supporting it. I no longer have Windows installed on it so I cannot update the secureboot key that way. However, I have LUKS encryption enabled and I have the device configured to shutdown if the alarm system gets triggered at home. Even if they access the device, they’ll have a hard time exfiltrating any data from it.
Linux fwupdate can do it.
Or person can do it by hand.
There is no money in it.
If your device is supported by fwupdate. For some reason, none of mine are supported by it.
You’re deliberately confusing the terms. A CPU doesn’t burn out—that’s a minimum quality standard, not “perfect.” If a hammer breaks after the first strike, it’s not a hammer, it’s a knockoff scam or a defective product.
And no, brand or price do not matters. Mininum quality - it works as expected when used with manual provided.
And it is normal to expect it. And it is minimum to expect. Othervice it is scam.
Purp.
Sec Boot keys updates is universal. Mechanism do not depends on firmware update rutine.
You can do it manually.
Same as installing your own keys.
Except they are working, but a bunch of small issues lead to a crisis for both Intel and AMD, and this is pretty much only for what is the highest end from both companies. Shit happens sometimes, so why should I waste my limited energy burning multi-billion dollar corporations at the stakes over human mistakes that only appeared cause they were trying to optimize every last drop of performance possible?
I do all my firmware updates using downloaded files copied to a usb. I don’t use fwupdate. UEFI BIos updates aren’t just for CPU’s burning up. There are many other reasons why it is important. Security is one, stability is another and with AMD it is AGESA updates a critical software library used in computer motherboards to initialize system components during boot-up.
Neither AMD not Intel is in crisis. And even if they were. You really should not bother abot probles of multybillioners. They do not bother about your problems for sure.
Small issues - half baked demo like products without proper testing pushed to the marked.
I’ve updated my bios three times since I’ve purchased my B550 chipset motherboard from MSI. Twice in just the past year. . . it’s good to see if the manufacturer is doing it’s part keeping up with all aspects of technology improvements as time progresses. My last bios update was just a week ago. . .
Rich 
It required differently implemented 3rd party vendor products used over several months to unearth an issue that affect parts of the product-line sometimes. That’s not “a hammer on a first strike”.
it is not how this stuff works. In this particular case for sure. But also. Sometimes you need to test product for several mounts. You absolutely right. with 3rd party products. You are right.
If you need you do this to assure quality.
And there more complex thing is, testing routine is also more complex.
Including aging tests.
Yes. You absolutely correct.
And you do it before release
I feel that this question is religions for some ppl. Thats pretty strange.
I also have MSI motherboards in two desktops. Both have had up to 26 UEFI Bios updates each. I tend to keep on top of them when they are released. No issues with any of them.
Edit: One of them is a B550 and the other is an X570 chipset!
Edit: They are getting dated so I don’t expect many more updates if any. My latest on the B550 was last week.
This is not how this works. But in this case it is how it works. But also. Sometimes you need to test products for a longer times. That sometimes is when … what? You know beforehand that there is some issue? We are begging the question at that point.
These are products at the cutting edge of material science, electrical engineering, manufacturing etc., every few decades you will get a lemon. It happens. It sucks. It shouldn’t happen, but eventually it does.
My hardware all day any day
