7900x or 7900x3d

[GennaiosFX]

hello considering the 7900x3d is 50 euros more in my country is it goin to give a boost to gaming paired with an rtx 4070 super at 1440P resolution?

the build is goin to do some productivity tasks to but gaming is a big part of the build(7800x3d is a no option).thnx in advance

7800X3D is better gaming CPU than 7900X3D as it provides way more consistent results because it does not need to have to rely on a cross CCD scheduling optimizations.

Only get the 7900X3D or 7950X3D if you value multi-core performance for workloads over gaming performance.

For gaming the 5900X3D is not a good choice, it will be beaten by the 5800X3D pretty much all the time. If anything the 5950X3D might be worth a consideration.

Unfortunately OP can't get the better option here.

 

For the 50 euro difference in a gaming-focused PC, I'd recommend the X3D

I read what OP said, but at the same time they make no mention why. When it comes to gaming, the 5800X3D  7800X3D is the most sensible choice. And if productivity is the deciding factor, I wouldn't pick an X3D at all.

You are confusing the 5000 series and the 7000 series.

Why not a 14700 instead ?

Yeah, that was a typo on my part, but my point remains. The non-X3D will boost higher which is better for productivity, which generally doesn't benefit from the additional cache. So non-X3D for productivity. Games benefit from X3D, but dual CCD is a negative factor, so ideally you want a 7800X3D, not a 7900X3D

If you can afford a 7900X3D you can probably afford a 7950X. The 7950X is way better for both productivity and gaming.

Because it has 8 cores per CCD and two CCD-s while the 7900, 7900X, and 7900X3D all have 2 CCD-s with 6 cores and the latency between the CCD-s is high.

 

The issue with a 7900X3D and 7950X3D is that only one of the CCD-s has the 3D cache and both Windows and games have a hard time scheduling the software/game threads to the correct cores. And disabling the non-3D cache CCD for gaming makes the 7900X3D a 7600X3D (although a 7600X3D doesn't exist yet) and the 7950X3D becomes a 7800X3D,

 

There is another option for you, the 7900 non-X non-X3D. Roughly the 7900X performance with a lower power draw and less heat.

 

The 7950X is two 7700X, so its game performance matches the 7700X but it can be higher if the game can use more than 8 cores (extremely rare at this time).

 

And yes, the X3D chips have lower clocks compared to the non-X3D. So if a game doesn't know how to properly utilize the architecture containing the large 3D cache, the X3D-s are weaker than the non-X3D.

I saw 7800X3D vs 7900X3D .... either I'm blind or the post was edited

guys thnx for the answers,however I only want to know between 7900x VS 7900x3d not the 7800x3d,if it's worth the +50 euros,7950x3d is at least 200 euros more than the 7900x3d so I only want to know between these two,if the gaming performance at 2k is better for at least 50 euros more

As per my last comment, I've misread your post.

 

So to answer. Yes, 7900X3D is better than 7900X for gaming while sacrificing slightly the multi-core performance due to lower clockspeeds in multi-threaded workloads. If the difference is 50eur and nothing else is an option, I'd take the X3D still.
