I turned on the MSI PBO "Enhanced Mode 3" and set boost to +200mhz in the bios. It seems to hit that in games without any CO offset, which caused instability with the 7800X3D. Also the idle temps seem much lower, core is now 33C.

I can't figure out what this mode does and there is not much documentation on it, but the lower idle temps alone are a big plus. Higher clocks are good for old games that don't benefit from the vcache or threads.

Very interesting quotes here in this article, related to V-Cache processors:

Put simply, AMD simply didn’t anticipate the disparity between its own product and Intel’s. “Put it this way,” AMD’s Azor said. “We knew we built a great part. We didn’t know the competitor had built such a horrible one. So the demand has been a little bit higher than we had originally forecasted.”

McAfee went even further: “What I can say is that we have been ramping our manufacturing capacity — the monthly, quarterly output of X3D parts. That’s 7000X3D as well as 9000X3D. It’s crazy how much we have increased over what we were planning. I will say that the demand that we have seen from 9800X3D and 7800X3D has been unprecedented.”

I wouldn't call it as horrible as Dinosaur Lake but yeah, this is what you get for ignoring gamers, Intel. Well deserved worldwide panning.

Keep it up and soon you may get the same reputation as AMD used to have. Cheap and inefficient.

How about +100 or +150?
I was reading most of them can achieve +200 (5.45ghz) so I started there. I figured in the worst case, the boost algorithm will just not push it all the way. It's better than doing any CO, which causes random crashes on idle that are hard to fix because they don't occur on load.

I read this and INSTANTLY was inspired, so I made this as soon as I read the article.

"You know its bad when Frank Azor of all people talks sh*t on you."

That would be quite out of this world, if true. It would, theoretically, outperform 9800x3d by nearly 10%, based on clock speeds.

I am a little skeptical. I think AMD would mention it / demonstrate it.
If i were to "guesstimate", stock fmax will be 5450/5750

My recommendation for daily setup: CPPC = prefer cache and set +200mhz fmax with PBO (together with curve optimizer) and forget about that xbox gamemode
There are also some other bios options i cant talk about yet

Theoretical you will lose ~5% ST performance, in reallife less, but you will alywas have the cache benefit which more than make up for it
As a bonus, light to mid MT workloads is always faster this way (thanks to better/more optimized V/F curve on CCD0)

If you like to tinker some more (like me), and have the correct motherboard, you can set something like 102 ECLK and limit CCD1 fmax while leaving CCD0 untuched for something like 5763/5814. (real clockspeed difference between CCD's can be as small as 50mhz when you start to overclock them properly)

just my 2cent

Some games like cs2 would still require it, as they spread evenly across all cores on both ccds if the gamebar is not present. Of course, you can edit power plan so it always puts all threads to the ccd0, but it's still not 100% bulletproof solution
Think you overlooked the line regards some new bios options
All is solved, uninstall that xbox i'm telling you

Wow, nice. That would definitely make 9950x3d the fastest gaming CPU.

As a bonus, light to mid MT workloads is always faster this way (thanks to better/more optimized V/F curve on CCD0)

A theoretical dual V-Cache at 5450 / 5450 would then likely outperform either stock 9950x at 5700 / 5700 or the theoretical 5450/5750 in just about every workload.

But, as the article above states, and also how Amazon preorders are now sold out until March 26, it looks like this time AMD is indeed short of V-Cache product - even if AMD wanted to offer dual V-Cache SKU

Mmhmmm... your "guesstimate", lol.

The newer X870/X870E boards are actually a downgrade from X670E in some ways. They all drop the main PCIE slot to 8x if all the M.2 slots are filled. A few let you disable USB 4 to avoid this. This is a big drawback on boards that cost so much. This still applies if you have a PCIE 4 card in the slot, it goes to 8x. Seems like all the more reason to stick to X670E if you already have that. But the new boards do a bit better with memory OC beyond 8000.

And this at the end:

Overall, other aspects remain mostly unchanged but there is a high probability that AMD's Ryzen sales could overtake Intel this quarter. Budget Ryzen 9000 non-X CPUs will go neck and neck against Arrow Lake non-K, though AMD has a clear platform advantage.

I am of the opinion that KRK is NOT a full tier replacement for HPT. HPT provides 20 lanes of PCIe. KRK only provides 16 as per AMD's official page with specs. PHX2 only had 14 lanes. KRK is, at best, a generational upgrade to PHX2.

I await lab benchmark tests between HPT and KRK using largely comparable laptops set to the same TDP. I suspect that KRK will indeed be better in ST, but in multiple situations, I suspect that HPT will be better in MT, assuming they both have the same memory configuration. I also think that Radeon 780M will be broadly better than the 8CU iGPU in KRK until HPT hit's power/thermal limits that starts to throttle 780M a bit.

It's OK. You'll still be able to purchase HPT in the warmed over Ryzen AI 200 series, and HPT is still going to make for a really good laptop processor.
The named-by-AI AI 9 365 is in reality the 9850U going by naming Zen 4 introduced. AMD did an Nvidia there with half the std cores plus 6 nerfed cores and put a "9" product range sticker to capitalize on the NPU and "AI PC" marketing.

8 standard Z5 cores with 12 CUs would likely perform a bit better at all-core loads in real world 28W usage. 5c does help with efficiency in the 15-22W range.
