Is there any software to force a 7950x3d to use 3d cores, base cores or all of them by choice without rebooting and making bios changes?

The title.

I was thinking in picking one up, but the main thing I do not want to deal with, is an auto scheduler picking up wrong cores, or if I want some application for example a game to force it to use only 3d cores, I wouldn't want to need to reboot and disable all the others, etc

so, is there any utility or way with this CPU, to let the user tell the system which cores use, how and when manually bypassing the system choice?

AMD drivers should do this for you. If you don't want to deal with possible scheduling problems buy the 8core.

for example a game to force it to use only 3d cores

Chipset Drivers.

But do chipset or AMD drivers have the option to pick myself which software will make use of?

for example, there are games where the 7950x3d performs worse than the 7800x3d, is there anything in the drivers to tell them

With this .exe, do not even dare to use anything outside the 3d cores and if I am runnig it, only use non 3d cores for everything else, but don't touch the 3d cores unless is this game using it.

tried to find something for days but didn't saw anything like that

Not that I know of. Sounds like you want your work computer to be a gaming computer as well. Usually you have to compromise in some ways. The 7950 3XD is AMD answer to that, but it's up to the driver gods to assign the right cores.

I want it sometimes, and I would pay a bit more if I could deal manually with what AMD can't do automatically with the driver, but I won't pay the extra just to see the scheduler or driver picking the wrong cores and not making use of the ones that should half of the times, that's the thing.

If I could deal with it manually when the driver get's it wrong, I would pick it instantly over the 7950x but otherwise, don't see the point when is a constant hit or miss and you are just playing a toss the coin

You might find something like Process Lasso + affinity setting can do this. But no, this isn't possible out of the box.

In the few reviews that I watched, they all said that the interface to turn off 8 of the cores was done through the Microsoft Game Bar, and you start the bar before you start the game you would like to play.

Update: Here is the AMD link to setup the Game Bar and additional settings for the 7950X3D for gamming.

Get a Threadripper then...

Id say run it stock first and then do the tweaks to notice any difference honestly

Need to use Virtual machines, the reason I'm selling the 13 gen, it performs poorly with them.

too expensive and extreme for it. Need a middle ground, the x3d could be on paper a good choice for everything, but the reality is that it isn't unless they let you config everything manually. Getting a chip so expensive for multiuse, and then seeing it perform worse than the 7800x3d, it's a no go, for the premium they ask it doesn't make sense to purchase it under that conditions.

 

[dont whant to set it"']

The regular 7950X , set it up and fogget about it. Even more so if you don't need single thread performance, mine does its stock frequency of 4.5GHz at 1V after boost set to off. Or disable the CCD with the lowest average per core frequency and pretend its an 7700XT

I've read it, but all the scheduler talk is at a bios level, and I asked if it was possible to override things without rebooting every time and changing bios things.

Like for example, you see a game that the scheduler doesn't manage correctly and disabling the base ccd would give you a boost of 20% frames, but yet, you only have a break of 30 minutes or even less and then you need to think you are gonna need to reboot, change bios, boot again, wait for the system, boot all the software, etc everything again to resume things after the break and if you cannot do it live and by software, that time you though you have, it's halved,

then you think as to change things to play, then do the same to resume the work, and do that sometimes multiple times per day?

1 week before you throw the computer by the window, that's what I asked, if to change things I need to go to the route of rebooting and changing bios, then it's as good as if that option doesn't exist.

If some kind of software could let me do it live and manage it manually, would be perfect, I could set up some scripts, macros or defaults to do everything in just seconds, but otherwise, nah, useless for my specific case.

It does make a difference since there is only one of the two CCD's that has the additional 3D cash. When both processor cores use the 3D cash, it is allocated first come first serve. So, game performance can and will take a hit, this is why they suggested to use the new drivers and the Microsoft Game Bar to shut down one of the processor cores. In the reviews that they did use the game bar, they had better game performance then the 7950X, and had tad lower performance then the 7950X when they did not use it.

This is one of the reasons why also I think the 7900X3D makes no sense. When you run the game bar settings, you half the 12 cores to 6, you wind up with a bit lower performance then 7800X3D.

Hmm I thought the 3D Cache could only be accessed by the CCD it is attached to, not both. Otherwise I would think this core scheduling wouldn't matter.

That is what I thought, but it looks like CCD's crossed connected through the CPU cores.
