The chip enthusiast community has been waiting on this one since last year, and AMD finally pulled the trigger today. The Ryzen 9 9950X3D2 Dual Edition is officially real, officially named, and officially coming April 22, 2026. It is the first desktop processor to place AMD’s 3D V-Cache stacking on both core complex dies simultaneously, […]

Not gonna lie if fhe numbers rumored are right I kinda want to flip amd the Ole bird for not just doing this with the 9950x3d. Sigh...

while this sounds great on paper, I don't think there will meaningful real world benefits.
 
Keeping a keen eye on this but still waiting for that Zen6 part with 10 or 12 or more cores but I have a feeling we won't get anything official until the fall or maybe even CES 27.

Proving numbers (well technically finding them, but they're not like, missing or hiding but anyway) are prime that are millions of digits long where their FFT length is greater than 32MB (The amount of data that the process needs to do calculations) will be able to still fit within' the L3 cache of the processor for both CCXs. This will allow those calculations to happen at a faster rate. Compared to those sized prime searches needing to utilize the RAM of the host system doing the calculations.

Server grade hardware for Intel has CPUs with large amounts of unified cache, but AMD chiplet designs limits the amount of fast access to the L3 within' a CCX to whatever size that L3 cache domain is. Sure some EPYCs have all their CCX's with this technology, but for the consumer parts that are more affordable for the mass being able to buy a consume CPU that double's this ability will be significant for that specific, real world, use case.

Real world benefit.
 
It's funny watching the reaction to this:

Before Launch Everyone: I sure wish AMD would release a dual X3D part, 9950X3D should have had cache on both CCDs, Come On We want Cache on BOTH cores. Disappointed it isn't on BOTH cores, Do it AMD, Do It. etc....

Post Announcement Everyone: Meh, Pointless, negligible game performance increase, Won't Do Much, Going to be Too Expensive to be Meaningful, Not much Perf Increase, Worthless for Gaming etc...

I remember very clearly people wanting it on both cores, now that they are doing it, all I see is negativity about it's worth. People make up your minds!

I for one, welcome more options, and I think it's awesome that they can even do this from a technical perspective.

Now if someone would kick the Radeon team in gear
 
I think its because of well... the ones who didnt want it, probably didnt talk about wanting it when it wasn't available.

Those who did want it, are just glad they're coming out and got nothing to complain about.

I bet a lot of it is due to sour grapes. Since it wasn't available, people went for 9800X3D or 9950X3D and now they don't see why they should go to the trouble of selling their existing CPU, messing with their coolers to re-install the CPU etc. It's mainly AMD's fault for being so late. I regret getting the 9950X3D, mainly because I didn't need it and got it simply coz I thought trump would do something to cause its price to double or triple. Now I wish I hadn't so I could get this instead.

Any AMD representative, if you are reading this, get in touch with me, take your 9950X3D and give me a 9950X3D2 so I can stop saying that AMD disappoints.

I am sour about it. I want it, but after it was leaked and then disappeared in the fall, I went ahead and got a 9950x3d for my next daily driver.

Now if I change CPUs, I'll lose an activation on TurboTax 2025.
 
Aiight cool, now we got a Ryzen CPU with X3D cache on both CCDs. Now I'm just waiting for a single CCD to have more than 8 cores. Then I'll be really happy.

So I can relate my case if you like.

When the 9950x3d was destined to come out we were pretty much universally hoping for it to have dual 3dvcache. What the x3d2 is destined to have.

We complained, we asked, and interviewers asked. And they were told... without doubt. That the dual 3dvcache would not be a performance boon as people thought it might be. And that in reality it would make more sense to do the single with core disablement in order to meet the gaming need and still have good performance everywhere else.

Basically every thing you have said as a naysayer reaction is just EXACTLY WHAT AMD TOLD US initially.

So now we have to ask ourselves... did AMD lie? Is there some huge performance boon to have dual 3dvcache on a 9950x3dv2? And if there is why did they lie to us initially.

Currently we are just parroting back to them why it makes no sense for gaming.

I am NOT saying other workloads won't benefit. But for the past few generations the x3dvcache chips have been squarely aimed at the the gaming market. Ai workloads and other specific workloads that love all of the cache (and really should be on a Pro compute platform.) will love the 3dvache. It's a budget mans box at that stage for doing light weight programmatic processing like what folks are wanting in here.

So I'll reiterate and TLDR this.

What you are calling out as gnashing of teeth and whining and poopooing the dual 3dvache processors.. is EXACTLY what AMD told us.

IF these turn out to be great all around CPU's with 10% raw uplift for gaming at 4k... (I know it won't but still) I'll be a pissed off consumer with AMD because they then knowingly lied to us about the use case of dual 3dvcache cpu's.
