The 5800X3D can overclock some now too.

Yeah, IIRC it's voltage-locked and multiplier locked, but not clock-locked, right. Perhaps AMD have removed the multiplier lock for the 7000-series X3D models?

I don't actually have any X3D chips, though I'll probably dump one in my home rig to give it a cheap boost rather than forking out for Zen4 or Raptor Lake.

Punkenjoy · Jan 23, 2023

It will probably the same as other Ryzen 7000, betting cooling might just give you slightly better perf in multithreaded workload but overall there won't be an impact.

On Zen 3, the main problem they had as far as i recall is they were not able to send enough power or voltage to the cache die or at least they had issue controlling it. It supposed to be resolved with Zen 4. So we will see.

Can't wait to see the results. If the scheduler do it's job correctly (And that is a big IF lol), there is a possibility of big gain with this gen. L3 cache is a victim cache and if the whole CCD with the extra cache is allocated only to a game, it will means there will be less cache pollution from other thread. This could lead to some additional performance gain for the 3d stacked cache (and indeed, only on 2 CCD setups,).

I really think that Zen 4 X3D will be a killer for anyone who don't want to mess with memory Overclocking. (and i am one of those, For me, that is a big pain in the ass to do that and it take way too long. I have game to play and work to be done).

Does Overcklocking at least means, that PBO Curve is unlocked for all Mainboards? My B550 Board does not have PBO Curve for the 5800X3D.

yes

It could also be a big win for people running JEDEC spec RAM. For example, ECC RAM always conforms to JEDEC specifications.

Personally i think that under-clocking(for cpu's and gpu's) is the way to go for normal users as it normally improves efficiency and longer lifespan of components, overclocking does however test out stability of a system and that's why its used by reviewers and techsites. The AMD cpu's seem to be especially fond of fast ram, and "overclocking" ram may have its uses, but ram/memory is hard to overclock, for them its better just to get "better quality" ram rather than overclocking it.

It should be noted that i'm mad in the head and start to worry when temperatures in my computer comes close to 50 degree C, maybe i should just sit outside with my computer, i live in a place where it rarely gets above 5 degree C between October and May. Maybe my worry about global warming comes from the possibility that i need to stop using computers completely, not sure that its really possible to run a computer at 50 C with room temperatur at 50c.

Sounds interesting. Might actually pull the trigger, and go with an X3D chip once I make the jump to AM5.

Both the 16-core/32-thread 7950X3D and the 8-core/16-thread 7800X3D come with a TDP rating of 120 W, which for the 7950X3D is significantly lower than the 170 W that the 7950X is rated at. It's also worth noting that the T-junction max (TJmax) value is lower, at just 89°C, compared to 95°C of the 7950X and 7700X.

And the 7900X3D?

Jism · Jan 23, 2023

Ive bin saying this for some time, but appearantly with the newer series they designed a seperate voltage rail for the 3DVCache. Its no longer hooked to the CPU-core giving it pretty much carte blance in regards of OC'ing.

And throttling @ 89 degrees C....

It dont matter anyway. Its not like your going to get significant better results with a manual OC compared to what PBO already brings to the table.

Its a gimmick with a few percent.... if you know what you do.

Steevo said:
The 7800X3D only has one CCD and if it officially supports overclocking maybe they found a way to make the extra cache go faster, or its luck of the draw, or they are doing a really good job binning these dies to make sure there is at least some room.

Voltages are much lower on this second gen cache apparently. 5800X3D cache was considered beta. I wouldn't be surprised if their is OCing headroom. l mean the clocks for this gen are already much better out of the box.

I'm definitely waiting for reviews. I'm an odd duck as I'm interested in the 7900X3D the most. I want extra cores for productivity reasons, but not the expense of the 7950X. Still if reviews show the 7950X3D is more better choice in performance per dollar, maybe I'll be tempted.

I'm still waiting to see if AM5 will support ECC. I saw a post in ASRock forums a new UEFI/BIOS revision is on the way. Until confirmation my AM5 cash is collecting in a box.

Any thoughts on how this processor holds up in a CAD, BIM, and 3d work flow?

I'm not sure, I haven't seen benchmarks for these in the 3D cache cpu. But if they behave like other 3D rendering apps (cinebench, v-ray) then I'm afraid the extra cache does almost nothing. In fact, the 5800X3D regressed slightly in performance due to lower clocks vs the 5800X

AMD has been using "Overclocking" marketing on everything, even on items that were impossible to overclock by 1%, so I wouldn't hold my breath there is some performance to be gained by changing some parameters in bios.

Most Ryzen "overclocks" are also usually hurting boost performance and single core / low core speed, and are actually decreasing gaming capability of CPU - so exactly the oposite you'd want from a gaming / low core focused CPU.

Never seen AMD CPU throttle at 89c since that is its operating temp. Most reviews say it does not throttle it just has a higher operating temp. You can always undervolt and get a bit more out of it.

I just want to see the 3dcache performance with the 7000 chip. Maybe I will consider jumping on it but that depends. I still have some good years in my rig. If the performance is outstanding then maybe I will pull the trigger on that one.

I think the OC is over and the chips have features to utilize as much as possible from the CPU. undervolt is the way to go since all are power or heat constrained or OC memory. The CPU oc is slowly dying I think in a way we used to know it.

3dv chips has 89 Tjmax as spec by AMD.
The extra cache doesn't come free of limitations and besides gaming it seems to have more of them than benefits.

OK. Does it mean it will throttle or what are you trying to say? We all know about limitations and the TJmax and how the 3DVcache affects gaming and other apps.

*Watercooling or LN2 required....

Just set it up to use proper voltages. They boost up to something like 1.45v by default which is nuts.

OC for the non 3d chiplet only?

No, because 7800X3D is mentioned and have 3D cache on all cores

I seriously hope they don't gimp 7800X3D too much in terms of clockspeed

However I think the listed (higher clockspeed) on 7900X3D and 7950X3D is ONLY for workloads when 3D cache cores is not in use, as they only have 3D cache on 1 CCD.

"Up to" Boost clocks.

If they allow OC tho, why gimp the clockspeeds compared to regular versions?

Instead of throttling at 95 degree like any other zen4 cpu, it will at 89 degree.
So at same w consumption at full load you will need better cooling to avoid throttling.

But those 3dv cpu's come with lower TDP of 120w instead of 170w (or baselin w) and lower MHz so it might end up equivalent when it come to cooling requirements.
We will see.

The blanket is too small with the 3dv.
You can't have it all.
For gaming you don't really need "all" and as those are pure gaming CPU everything is fine really.
