9950X core parking

[brokebeardedguy]

I know the Internet likes to tell people they're wrong so I'm hoping someone will...

 

Bought a 9950x bundle on a whim... I've been waiting for some New parts to build a system I follow tech but not enough to know everything about everything and my understanding was the 9950x was the best multi use cpu.

 

It's my understanding the twin CCD processors all core park.... So if you have background processes open and you launch a game everything shifts over to one CCD? Effectively giving you an eight core processor. 

 

So anytime you use the PC for gaming it would have been cheaper to just buy a 9700x? 

 

Currently I run an older 10940x with 64gb of quad channel ddr4. Trying to read and understand I've gathered that ddr5 dual channel would be comparable before jumping from 3000mhz to 6000mhz. So the ram part is a huge uplift. I also understand generational improvements and IPC gains...   

 

My concern here is that if I try to play games while I'm waiting for other tasks to finish I'm going to effectively give up half my processing if I launch any games.

To my knowledge core parking arose due to the more than 8 cored 3D CPU's. AMD only had the extra 3D cache for half the cores for 12 and 16 core models, which isn't a fault in of itself, the fault arose when windows placed workloads on the non cached cores that was noticeable in games as people sometimes never saw the 3D gains they paid for. The fix was to park the non 3D cores and then play games, as doing this would ensure that no matter which CPU windows puts the work on when playing games, there was a 100% chance that it was a core with the extra cache.

 

I think Intel also had a similar scheduling issue with windows because it wanted to put gaming workloads on the slower e-cores.

 

Since your CPU isn't a 3D one, this problem won't happen.

 

I'm gonna wait until someone more knowledgeable comes by and corrects me.

Even if this were true, which it isn't for non-x3d chips as far as I'm aware, you'd still reap the gains of having only the game running on one CCD, while the rest of the system runs on the other CCD. Additionally, the point of having more than 8 cores isn't to improve gaming, it's to improve performance of things that aren't thread limited. Finally, you have confused the 9950x with the 9950x3d. The x3d is the best multi use chip because it can core park and run games on essentially a 9800x3d while still offloading background tasks to the other CCD

No confusion. It's why I stated all dual CCD chips. The 9950X core parks and does not have 3d V-cache.    My goal isn't to improve game performance. But overall performance. I've been reluctant upgrade because of the issues with both and and Intel turning off cores or putting loads on the wrong cores... 

 

Jayz2cents did a video recently and when core parking occurs it shuts off one CCD... So how do background tasks get off loaded to it?
