New game turbo mode appearing in BIOSes

ASUS updates 80 AMD motherboards: first release with AGESA 1.2.0.2A and "Turbo Game Mode" - VideoCardz.com

ASUS has an update for its AM5-based motherboards Update mainly for Ryzen 9000X3D. ASUS is updating its X670, B650, and A620 motherboard lineup to support the newly announced Ryzen 7 9800X3D processor and likely the upcoming 12- and 16-core SKUs. The update, announced yesterday, includes...

Example above. Seeing reports of the implementation of a game turbo setting in BIOS as they are updated for 9800X3D, but applies to other CPUs too. Would it be so hard for anyone to describe what it does? Some claims of it turning off SMT, and/or disabling one CCD for dual CCD CPUs. Improvements... I'm guessing we'll have to wait and see for the usual testers to go through it in more than 3 games, but I'm not expecting more than single digit %.

I'm wondering if each vendor has their own special sauce...

I also thought, in this gen, the dual ccd problem was mitigated, at least to some extent, in these cpus? Both ccds having acces to the full cache or something?

I haven't heard anything about that. Maybe there are some minor tweaks somewhere, but as far as I'm concerned the split CCX problem is the same since it existed.

I have been searching around a bit more. I've not really seen any reports beyond disabling one CCD and/or disabling SMT. It'll take more controlled testing to see where it helps or not.

While the above link was for Asus, others have implemented similar. It isn't clear to me if this is something AMD suggested/required, or did one of them do it then all the others felt a need to copy?

I think that is the current rumors for the 9900+9950x3d but nothing official

I might be misinterpreting things. I have seen talk about the possibility of both CCDs having 3D cache in unannounced Zen 5 parts. To me, that addresses the unbalanced problem for some workloads, but doesn't address the split from a gaming perspective. If they could have a unified L3 cache, that would be really something.

The new BIOS is available for your mobo, so you can try it and find out what it does. I won't have the time for that in the upcoming days, so I guess you will find your answer faster than I can test it.

Like I said before, I guess it might give low single digit %. In other words, a waste of time to test it unless you make content based on it. I'll wait and see what others report.
