Of course, AMD is always right. I think it's pretty clearly a most useful part. AMD is talking about energy efficiency improvements on a 200W part. Neato.
Yeah, unclear what that means. Are they talking about perf/watt? If so and it has 200W TDP, it ought to mean noticeable perf increase over 9950X3D which has 170W TDP. This since 200W > 170W, and 9950X3D2 also has better perf/watt.
Why bring TDP into this at all
Just keep your head in power limit land and keep things simple
In any case, the key "problem" with this part is its name. It should be named Eypc something or another to keep gamers and YouTuber's filthy paws away from it.
Because we're not only in power limit land (it depends on the use cases and the user's needs). And when comparing total perf, it will be higher at 200W compared to 170W TDP.
You also have the case with 9T-16T (note: not 9C/17T to 16C/32T).
Then with 9950X3D2, all of those threads can get a dedicated core (i.e. no SMT needed slowing down perf/thread) and also access to X3D cache at the same time.
With 9950X3D, threads 9-16 instead have to choose between:
a) Being on the CCD with X3D: Access to X3D cache, but no dedicated core and thus have to use SMT shared with threads 1-8.
OR:
b) Being on the CCD without X3D: Deciated core for threads 9-16 (and 1-8 of course), but no access to X3D cache.
What on earth are you on about? TDP does not matter. AMD can say it's 65W TDP and still set the PPT to 200W.
You cannot tell anything about the efficiency of 9950X, 7950X, 9950X3D, or any other ""170W part"" from the TDP because none of them are 170W and AMD's PPT is no longer a function of TDP.
Ignore TDP. It is meaningless unless you are an OEM cheaping out.
I could be a thing, if you count Joules it takes to complete a task.
Joule is a better unit for efficiency.

So you want to see people saying 720000 j/h part ? Seems inefficient in chars alone.
9950X3D2 is a CPU for two groups of people:
Rich AMD fans
Rich Cities: Skylines 2 players
That games loves thread count and cache, it's rather unique.

Apparently there has been a new stepping Zen 5 already.
Oh, no, another victory lap for Tom from MLID incoming. He doubled and tripled down on his prediction that there will be a new stepping that will enable higher clocks. Not just for the new V-Cache processors but across the board.
Maybe a hint? Threadripper 9000 and many Turin have stepping 1 as well.
That's a truly great achievement replacing Strix (Jun 2024 - Jan 2026).
The best part is partners obviously have known that Strix got no real replacement planned till 2027 all the way since 2023/2024.
Same people that currently buy 9950X3D (or 9800X3D if looking for 8C).
If you don't care about absolutely max perf and want to save some cash there are other CPUs to buy with better perf/$. Does not even have to be AMD.
Not exactly. 9950X3D already had the best bin of both CCD types.
9950X3D2 is only for people who have scheduling issues and would like to pay even more for that pleasure. That's why I really think it should be an Epyc part, but oh well.
Plus the L3 is coherent only through IF, so how much is it even going to help Cities 2 compared to 9950X3D? I would guess very little.
So you don't think 9950X3D2 will perform better than 9950X3D (and 9800X3D) on average for games?
So 9950X3D2 is for the same crowd that currently buy 9950X3D and 9800X currently after all. I.e. willing to to pay a lot to get absolutely best perf.
I bet it'll perform even worse than the 9800X3D on TPU summary of game performance at 720p. Maybe on par. And that's throwing 400MHz and a crap load of silicon at an already solved problem.
Really, really should not be marketed to gamers.
Why do you think 9950X3D2 will perform worse than 9800X3D?
Anyway, it'll be interesting to see the benchmarks.

For people who already have 9800x3d or 9950x3d, the performance uplift is, IMO, too small to justify an upgrade.
Maybe Zen 4 owners, doing a CPU only upgrade or upgrading older systems (the best candidates).
With these new CPUs not released yet, and Zen 6 likely less than a year away, waiting to upgrade may be the best idea.
