9850X3D and 9950X3D2 rumours.

Hmmmm do I upgrade or not?! :D

The IMC on my 9800X3D isn't the greatest for running 64GB (2*32GB). Can barely get it stable at EXPO settings. It didn't crash much, maybe like twice a week it would fart while playing BF6 which I initially just put down to the game until the same thing then happened in D4. Seeeeeeeeeeeeeeeeeeeeeeem to have fixed it now (2 weeks no crashes) with more SOC voltage (1.295V) and this could be my excuse to sell and try again with a new (9950X3D2) CPU. Of course could end up with an even worse one...

Yeah doesn't sound like the greatest imc. Mine will do 64gb at 6000mhz expo on 1.17v soc if that is any reference
 
Kinda tempted by the 9850X3D as my 9800X3D isn't the best sample. That being said, feels like a lot of effort for a few hundred MHz I probably don't need.

Yeah, honestly this is a pointless upgrade for anyone on a zen4 or zen5 X3D chip I feel. Wait it out for Zen 6

Pretty much this, going to be bare minimum gains if you are already on a new-ish X3D cpu.

Im still on a 5800X but going to hold out until Zen6
 
The 9850X3D I think is going to be more for people willing to either pay a (probably pretty) premium for the best of the best, OR who do work with thier machine as well as game; as realistically productivity and number crunching is where that extra MHz make a major difference, which most games except some RTS etc are not extremely heavy on.

The key gaming benefit is the gigantic cache reducing latency for frequently accessed data; and the impact that then has on both allowing the CPU to leverage its IPC, and avoid the bottlenecks and latency imposed by the memory IO die and to system IO; not the clock speed itself. (hence the differential between Zen 5 and Zen5X3D for gaming, which is sometimes fairly major, despite having an otherwise equivalent core); in otherwords the gaming bottleneck is the latency to memory and other system components (and to a lesser degree throughput), rather than the IPC of the CPU itself.

These will be ideal for someone who games, AND does work so wants the best of both worlds, and can actually make use of the extra clock speed, without jumping up to a higher core count chip however.

With memory prices now through the roof for even more moderate low latency kits, finding ways to offset RAM latency and IO die/chiplet latency, is more critical than ever for AMD when it comes to gaming.

Wasn't this released as there will be a delay into 2027 for Zen 6.

Yeah possibly, but 400mhz increase on exactly the same architecture seems a pointless upgrade for anyone (9800X3D or 7800X3D) unless you really are desperate for a few extra frames

that few hundred mhz for certain tasks [non gaming] with the cache added would be rather attractive... to the point il be keeping an eye on it at release to see if it might be worth
me swapping my 7800x3d out for one on the music making machine, although i doubt it would be worth it and i probably should just wait for zen 6 and upgrade then, I haven't even
put the zen4 rig together yet hopefully doing that next weekend lol. but it will be interesting to at least look into for me. see how the 9850x3d does for music production tasks.

Nothing on the 9950x3d2 annoyingly.

Semi official(ishl:
www.computerbase.de

X3D² bestätigt: Der AMD Ryzen 9 9950X3D2 mit doppeltem 3D V-Cache kommt!

Seit Wochen ein Gerücht, hat AMD ihn jetzt offiziell in Aussicht gestellt: Den AMD Ryzen 9 9950X3D2 mit zwei CCDs mit 3D V-Cache.
www.computerbase.de www.computerbase.de
But just a "Stay tuned" for now.

Alienware China and some other integrator have holding pages:
www.sytronix.co.uk

AMD Workstation | Sytronix

www.sytronix.co.uk www.sytronix.co.uk
And
So something is coming.
 
I'll be very interested top see if the X3D2 solves the stuttering issues when games split across both cores. In my experience the 9950X3D can be iffy on this, though my issues seem mostly sorted now. For a while I was getting a lot of stuttering in VR games.

Would be nice not to have to rely on third party software or MS game bar to set the core affinity for games.

The latency between the CCDs will always exist due to the chiplet design. It's whether the cache on the secondary CCD can mask that. We'll have to wait and see...
