The obvious question after that statement is: which part is not overclockable according to AMD? Is that just the consequence of how the clock management was developed?

Also, in reality, there's no such thing as "not overclockable" IMO and it will depend on what is exposed to the motherboard in terms of voltage control, multipliers and such.

It's definitely not a good message to put out there, but I think the devil will be in the details.

Regards.

lol lets hope this is not the case. who would buy this chip if that was the case. the current intel chips would smash this chip for the same or less cost.

Which ryzen chips can overclock anyway? They're already at the limit.

Heat was always a concern of mine when I heard they were going to stack chips. Eventually backplate heatsinks are coming with an entirely new socket design to support it where CPU pads are outside the core area to allow an open area in the middle on both sides to cool.

The problem I'm finding with this is what "overclocking" even means anymore in a given context. Because in my eye, there's two types of overclocking:

• Forcing the CPU to run over its stock base speed, which I argue when placed in a vacuum, this is what "overclocking" should mean since this is how it's always been done.
• Allowing the CPU to run over its advertised maximum turbo boost speed.

In any case, if a "locked" AMD CPU simply means you can't change the multiplier past, in this case, 45, then you can still do base speed overclocking. Setting a value on the multiplier forces the CPU to run at that speed all the time. If it's say disabling PBO features or whatnot, a little more painful, but not exactly a huge loss considering you can barely push the maximum turbo speed on Ryzens anyway. Plus said maximum turbo speed is only good for the preferred cores.

This is somewhat stupid claim... Even low end AMD CPU you can "OC"... Not much, but you can. The problem/advantage is that there is no point doing OC. The extra cache needs more power, so it may be even harder to OC 3dcache versions and 3d cache can cause OC bottleneck on its own depending on how closely the cache affect the cpu clockspeeds. All in all you need hefty LN2 or similar level cooling to OC anyways so it does not matter. I also expect that there are no OC locks, but just physical things that just make OC hard (like it is already with 5000 series).

What i expect is that this is engineering sample and there quite often are some limitations with engineering samples...

PBO effectively makes manual overclocking mostly pointless, and hopefully theyll be a good upgrade option for anyone thats on a B450 board or newer. If youre happy with your current setup why change out your whole platform when you can just replace your cpu and get a nice performance lift?

 

[Friesiansam]

If your usage case would benefit greatly from the extra cache, I doubt the loss of clock speed is going to be a problem. Just make sure you cool it well enough, to ensure it runs as fast as possible.

None of the latest high-end CPUs from either AMD or Intel have any significant overclocking headroom. Outside of temporary, exotic cooling solutions to push high scores on benchmark leaderboards, overclocking can just manage margin-of-error-level improvements at best, and performance regressions at worst. High-end CPUs are now being designed to get the most out of the silicon at stock, precisely adjusting clock rates and voltages on their own. And due to binning being performed on the chips at the factory, lower-grade silicon is put into more mid-range processors to match with their lower clock rates, so those are less likely to overclock significantly either. So really, overclocking support is mostly just being kept around at this point to check off a box on the product sheet to assure enthusiasts that a chip is in fact a higher-end model, even if there isn't much to be gained from it.

And of course, AMD has stated that the 5800X3D will be the "World's Fastest Gaming CPU", so I don't think the Intel chips will "smash it", as it will likely hold the lead in at least some workloads. Whether that justifies its price is yet to be seen, but there are people who will pay a big premium for imperceptable performance gains, like those putting 12900Ks into gaming systems, rather than processors costing around half as much with very similar gaming performance.

 

[drea.drechsler]

As stated...overclocking is pretty much pointless anyway. The way to push my 5800X is undervolting with Curve Optimizer. So the question is: has AMD taken PBO and Curve Optimizer off the table too?

It doesn't sound like a hardware lockout if AMD's asking board partners to not allow overclocking. I expect leaked...or hacked... BIOS's to show up for some boards anyway and attempts made.

 

[Sleepy_Hollowed]

I am totally OK with this.

I have not overclocked anything besides RAM (beyond JEDEC standards that is, via XMP) since like the 3rd or 4th gen Intel Core CPUs.

Stability is way better that way, I really hated having random crashes or artifacts due to CPU or GPU manual over clocks.

 

[SkyBill40]

I'm sure there's SOME headroom, it just might not be as much as a regular 5800X. There had to be tradeoffs for that extra L3 cache, with this being perhaps one of them (along with the already decreased clocks).

problem is that PBO is also blocked on this cpu

Which is retweeting an article that sourced information from the same place as Tom's.

The original article makes no mention of PBO. The tweet is adding PBO to the unsupported features list from the linked article. Raichu is a well known leaker.

And we should treat all leakers with skepticism, not as prophets, regardless of how "reputable" they are.

 

[spongiemaster]

Not sure what the hostility is about. Someone asked for the source, and I gave it. Whether or not you want to treat it as a prophet is up to you. I made no such claim.

 

[-Fran-]

I thought the "may be" implies "possibly not and this is complete speculation". Unless it was confirmed by an independent entity?

Then again, I stand by what I said: you can always overclock. It'll come down to how user friendly it is.

"Know?" Well, we don't know for sure. But we do know that AMD lists the Ryzen 7 5800X as being "Unlocked for Overclocking" while the 5800X3D makes no such claim. I don't think it's an accident that the 5800X3D fails to list that feature. There's also this sweet clip from TheFullNerd:

you wrote that “high end” chips don’t have too for overclocking. But hate you seen the amazing things possible on the newest i5 Alder Lake chips? With a permitting motherboard there is a BLCK OC which takes that $200 chip up to performance that outpaces my 5950X in games. It is remarkable. So there is huge headroom on these chips still (the devil is in the detail though - today, only higher end z690 motherboards have these feature needed to let these chips OC all the way… but it would just take a Chinese manufacturer to add it on a $120 board and this easily wins “best gaming CPU”)

Well, as far as overclocking goes it's speculation that may prove true. But as far as PBO goes all that seems to be doing as asking the question...no speculation.

Whatever the case may be, we'll know soon enough.
