What do you think the 9800X3D will commonly reach up to in CPU clock speed?

[RaceT3ch]

Since the 9800X3D is the 1st unlocked CPU with 3D cache, thanks to its cache being under the cores, what do you think the 9800X3D will reach?
Remember the CPU cores and the cache have to stay in sync, so there's two limiting factors being the cores and the cache.

Me personally? I think it'll reach 5.5, matching its non X3D sibling 9700X.

Are we talking regular boosting behavior or OC? And if OC, how extreme are we talking?

OC, up to custom liquid. Basically, as best as you can get while not having to do constant maintenance and fixes. (Like how LN2 causes crazy condensation, requires some weird copper cooler, etc)

As far as I'm aware, PBO only allows up to +200mhz, so 5.4 GHZ. That already matches the 9600X

@RaceT3ch
Then the answer is silicon lottery. But overall, probably 100-200Mhz lower at the top end compared to the non-X3D parts. All-core, I assume. This, counterintuitively, will still probably end up being overall slower in practice than just regular boost + PBO Curve Optimizer.

Haven't OC'd Ryzens since 3600, just used PBO +200 myself, but with those, I'd guess that 5.4 is something that it will reach.

Cores & L3 cache have separate clocks on 3D V-cache CPUs. They have no need to be in sync.

I think AMD selects it's chip so well that there most likely be "nothing" to be gained. I tested several CPUs with my sold B550 / AM4 plattform.

We'll see in a couple of days. Anyway, I voted 5.3-5.4 because that's what the TPU review sample of the 9700X achieved, and I don't see even an unlocked X3D with the extra cache on its back side going further.

The AMD Ryzen 7 9800X3D 3D V-Cache CPU was tested on Geekbench 6.3, using the ROG Crosshair X870E Hero motherboard with 32 GB of DDR5-6000 memory. We saw in previous benchmarks that PBO can push clocks close to 5.3 GHz (5.2 GHz stock) but this time, the CPU was clocking at around 5.5 GHz.

AMD Ryzen 7 9800X3D Tops Single-Core Performance With 5.5 GHz Overclock, Multi-Thread On Par With 7950X & 265K

AMD's Ryzen 7 9800X3D CPU has been benchmarked again, this time scoring an impressive ST score with 5.5 GHz overclock & great MT performance.

bloody hell, they managed to get higher single core than 9950x despite only going at 5.5?
that cache does a lot outside of games

I'm planning to delid and direct die cool it (or kill it trying) to see how high I can push the clocks. Hoping for 5.8 all core in non intensive loads and 5.5 in a stress test.
