5950x w/PBO vs 5800X3D.

[Celestron]

Im itching to pull the trigger on an X3D to swap out with my 5950x. Workload stuff has fallen off as of late and its just mainly gaming now. I can even make a little money if I sell the 5950x. From what I read the 5800X3D cannot be overclocked and that there is no PBO option. Is that correct? I have my 5950x with PBO enabled and its clocks are pegged at 4.9/5.0 during gaming. 360mm AIO in combine with the H500M case keep the chip incredibly cool at 61c max.

So I wonder will I actually see a performance increase in single core applications with the X3D? I cant find any specific information on tests with 5950x PBO enabled versus the X3D. The X3D doesnt boost as high so it makes me wonder.

There's also the matter of longevity. That being about two years or however long it takes for the next GPU/CPU generation. I dont plan to build new until then.

 

Edit: So you can OC the X3D... But you shouldnt. Which again makes brings more doubt with switching. Especially because I can push the 5950x to 5.1 if need be. I have an excess of thermal head room.

 

Edit2: GPU is a 3090 with a display resolution of 3840x1600. Go-to genres are just about everything but shooters. I play lots of cpu bound games.

the difference in gaming performance would be pretty small. Yes the 5800X3D is faster, but you may not notice, especially since you're playing a higher resolution which will be stressing the GPU a lot more

No amount of overclocking can bring a regular zen3 close to the x3d in games that require strong single-core performance.

 

None of the mentioned CPU-s will be outdated in 2 years. And none is a bottlenecck for the 3090 on 3840x1600.

 

The 5800X3D would draw less power, that's also a valid consideration.

**edit**

 

Realized you said 5950x but the argument is the same. 

 

There are tweaks that can be done with the 5800x3D but it simply doesn't matter. Due to its design with the additional cache, its just always going to be faster in gaming regardless of clockspeed. We've known this since launch. That being said, the difference at 3840x1600 will likely be small. Probably not worth it and just wait a bit for an AM5 upgrade later.

 

On average, this is the current 1080p general ranking for a group of 12 popular games so you can see where they stack up.

in theory on paper the X3D is probably the fastest gaming CPU on the platform.. however.. it's sort of a matter of "having 280FPS instead of 270FPS" in most games. (exact figures were extracted from my rear end, just to draw the distinction.)

 

in other words.. it's difficult to warrant the effort unless if the downgrade guarantees you can sell at a net profit, and could really use that money.

Since I actually own this processor and have "overclocked it"  I can speak on this:

 

Temps on this CPU are higher than a 5950x but it uses half the power. Vcache makes the core run hotter.

All core boost is 4450mhz

Single core boost is 4550mhz (you won't see this on most motherboards)

BCLK can be increased with an external clock gen from 1-3% results vary from config to config.

 

Some motherboards allow for NEGATIVE curve optimizer. This helps reduce temps and improve multicore performance. If your board doesn't support this there is a windows tool available to perform this function.

 

5800x3d will boot on any ryzen 5000 supported bios, however it will be locked below 4ghz if you don't have a supported bios.

Thanks a bunch for the insight all.

I went from a 3900x with loads of OC to a 5800x3d and its also oc to 4750mhz, It made a diference, on games that really need the cache yes it makes the diference, on the rest yes it improved due to the better IPC, If I had the 5950x i wont get the 5800x3d, just keep the system and upgrad to AM5 if you call sell that one, or just hold and wait. 

 

The 5800x3d when OC is really hot, I have a 360/60 rad with push pull and another 120mm rad with push pull and it will get to the 80c, but damm its fast, specially on star citizen 40fps to over 120 gpu always at 100%.

If your X3D is hotter than your 5900X/5950X then you should think about replacing your cooler..
