This guy is such an idiot, its prioritising the CCD with the cache when gaming for the best performance, its not a "problem" its by design, its does not have a "dummy CCD on it" its a full dual CCD 16 core CPU.

He's special. How sweet to be an idiot. Imagine knowing someone like that. How embarrassing.

Gordan said where he ran SOTTR and then a browser and then a R23 using only 4 threads and it all went to the Vcache die as it forces everything to run on the Vcache CCD as game mode, but when he used 16 thread for R23 it woke up the other CCD.

So hair chasers is dramatizing it but its sort of true, but you know he disables e-cores.

Yes its parked, like any core on any CPU is parked when not in use, its not a "dummy CCD"

Sorry I was talking about the PC World video. He tested it and when gaming using Gamebar the second CCD was not used at all for any tasks running as well as the game. It stayed parked unless he ran something in the background that used all cores. This sounds like an issue as when gaming the rest of the CPU is not utilised. No one side anything about it being a dummy.

The question needs to be asked, who in their right mind would use Cinema4D or Blender while playing a game?

It looks like its telling Windows to park the CCD without the 3D cache on it and keep it parked when playing games.

Its an interesting observation, but its not an "Issue" and its certainly not a "Dummy CCD"

This guys channel thrives on getting people who don't know any better wound up.

I’ve not once seen him show his testing methods, only his results. For that you must buy a “consult” apparently.

Ok, what's the alternative?

 

[Hostile_18]

So it sounds like its right though, if your "just" gaming you essentially have a 8 core cpu but paying 16 core prices? It's not exactly clear in the marketing tbh.

As I said earlier 7950x3d only really makes sense for gaming *and* production.

The 7900x3d however makes sense for no one, relative to other offerings.

 

[B1gbeard]

My point is that this should have been covered in reviews. It's basically been ignored by the majority. If you game you are essentially getting an 8 core CPU for £700.

Depending how much you do of each the 7950X might make more sense. Also the 7900X3D would make a lot of sense for those looking at cache intensive workloads and a bit of gaming.

Yes, its an 8 core CPU when playing games and 16 core for everything else.

The alternative could be to put two 3D cache chips on it, but that would make it more expensive, unless its going to make a difference to gaming performance only having 8 cores available for gaming we don't want that, i suggest having 16 3D cached cores is not going to make the blindest bit of difference so in a situation like this AMD cannot do right if the critic is already looking for something to be critical about.

It is a 16 cores CPU when you need it to be, it does not have a dummy CCD on it, that is the most ridiculous thing i have ever heard.... its working as intended.

The level of copium on display here is glorious

Also, Intel's Hybrid CPU's work in the same way. it doesn't use the E-Cores when you're playing games.

How is it a 16 core CPU if it doesn't use the other half when gaming? What about if you want to game and do other things like stream? Or even do some work in the background that doesn't wake up the other CCX? No one said anything about dummy again not sure where that is coming from. What you are describing is the 7950X, not the 7950X3D.

No but it does for other tasks when gaming. The 7950X3D does not when gaming. I suggest you watch the PC World video to better understand. It's not a dummy, it is just not being used at all when gaming.

Working as intended would be game on the X3D CCD and background tasks on regular ccd. But that's hard to do without a thread director so you get an all or parked situation.

What? Why?

You're just plain wrong here. It absolutely does.

It uses them for background tasks. I think that’s where he makes a point. Basically he’s saying that when gaming it’s going to shut off the other cores completely so they wouldn’t be used for even background tasks either whilst gaming.

I was discussing this with someone the other day and how a dual 3D cache of the 7900 would be a monster, but probably cost way more than the 7950X3D.
