I've said it before. Intel CPU teams should resort to working only on their server products and refine their architecture while for client, they should just buy Ryzens in bulk and rebrand them.

Intel Core Ultra, powered by the Ryzen technology you know and love.

Ever wanted to XTU your Ryzen? With the brand new Core Ultra based on Ryzen technology, your dream has come true!

Intel Core Ultra 3D powered by Ryzen technology. Let your games fly.

Unintended side effect: AMD becomes a MAJOR supplier of CPUs to Intel and decides to exit the client market coz they don't have enough to sell direct to consumers!

What a hot mess. This board only has a beta bios, I'd be bent.


He provided an update in the comments -

Actually after the video now even with my preferred settings timespy is failing and also chrome crashes frequently which it didn’t previously, so i am worse off now than the video would suggest so the title is now more accurate than the actual content would suggest at the time to some people that don’t understand the subtle difference between broken and unstable which to me are essentially the same thing

This model used the Intel default profile after update which killed performance. Requires user intervention.

It is even better, the next thing they list is "cpu scaling performance optimizations". Maybe the new version of snowdrop engine is scaling better with cores or it is just mumbo jumbo nonsense from devs and marketing as per usual.

Maybe putting some non-critical threads on the E-cores and pegging the critical threads to physical cores and avoiding the virtual HT cores through "hints" to the Windows scheduler. But if it's just scaling optimizations then those should work on Ryzens too.

As I read on a french website (don't remember where, sorry), this might become an 'FDIV - The Return'. A real nightmare.

Updated the BIOS on the lone 12th gen Optiplex I have access to at my office.

First off, Dell sneakily inserted something called SafeBIOS through some Windows Update coz it wasn't there when the last time I updated the BIOS (version 1.23.0).

That horrible SafeBIOS is making me write off Dell completely because I can't find a way to disable it or get into the BIOS anymore, even with the firmware boot parameter of the shutdown command which used to work reliably before.

Anyway, post 0x129 microcode update, Core i5-12500 CPU-Z ST went from 736 to 722 but all other benchmarks seem to be within margin of error. If there IS a performance downgrade, it's not with 12th gen CPUs, methinks.

Only other discrepancy I found is in Silverbench:

Weird that normal score decreased but the extreme score actually seeing an improvement :oops:

I think you have to get into the BIOS and turn off Secure Boot to disable the Dell SafeBIOS.

Not working anymore. The initial Dell logo is not appearing onscreen anymore and no message appearing to press F2/F10 for options. I tried to keep pressing F2/F10 multiple times as soon as Windows restarted. To no effect. It stays blank during the boot up phase (looks more like memory training phase on Taiwanese mobos) then immediately goes to Windows loading logo which is now Dell SafeBIOS logo (Windows loading circle appears under it).

The shutdown /fw command was the previous reliable way to get into BIOS but it's not working anymore.

I have to side with Dell on this one. They are likely being hit the hardest by the faulty CPUs. Desperate times desperate measures and all that. Intel and Dell have revived the Hitler in the bunker meme.

I would never buy a Dell or HP anything. Sadly my work gives out Dells, they are so buggy, slow and loud. My Lenovo ThinkPad from high school was much better.

Lenovo Thinkpadz are the way to go.

P.S HATE DELL BIOS UPDATES. They always break my microphone and webcam drivers and sometimes me make late for my meetings.

It sounds suspiciously like Dell is PREVENTING people from turning off HT in BIOS.

Maybe that option is not removed from the current BIOS so they simply disabled access to BIOS?

Very true. They take so long to complete like they WANT the PC to get bricked with a sudden power outage so they get one in for repairs and charge the customer!

Probably a stupid question, but have you tried doing a Windows shutdown, unplugging the power cord for a few minutes, then plugging it back in and trying to restart? On the older Dell my mother has, it makes a difference as to whether the Dell BIOS screen appears.

If this doesn't work, it might be worth posting a question about this in the Dell support forums to see if they can explain why Dell made the decision that they don't consider you to be either trusted enough or intelligent enough to be allowed to access the BIOS on your machine that you own. The answer might be amusing if nothing else....

Unfortunately, can't do that with the office PC. The power socket is recessed deep under the desk.

I don't care enough to go to that much trouble. It's an annoyance for me. Could be a huge issue for my IT guy if he ever needs to get into the BIOS. I'll let him harass Dell support when the time comes. He's pretty good at harassing customer support :D

Lenovo Thinkpadz are the way to go.
I used to run a 3y old Lenovo P1 as my work computer. It was so power hungry that it could not charge through USB C. And as soon as you plugged the power brick, fans started. And it wouldn't last more than 2 or 3 hours without being plugged in. Can't say how other brands do, but if Lenovo are the best...
