Well we know now how they will bridge the long wait to Zen4 on AM5 Q4 2022.
Production start for V-cache is end this year so too early for Zen4 so this is certainly coming to AM4.
+15% Lisa said is "like an entire architectural generation"

Chill Out Dude.

It's a Niche product to regain the "Gaming" Crown(for reviewers at 1080P using a 3090 lol, because at 1440 and Up there is no difference between current Zen3 and Alder Lake), that will give people an upgrade path if they so desire on their AM4 Platform.

This Chip will become an Afterthought when AM5 Zen 4 land and star laying waste..

Intel Core i7-12700K Review - Almost as Fast as the i9-12900K

With the Core i7-12700K, Intel has released a formidable competitor to AMD's Ryzen 5800X and even 5900X. Thanks to eight powerful Golden Cove cores, the processor handles all workloads very well, including gaming. Compared to the i9-12900K, it runs almost as fast, but much cooler, with better...

i'm at 3440x1440p Ultrawide so I need to see final reviews cause I'm not sure the gains would be there in my setup going to this chip. Will find out soon enough.

PBO on my Zen2 and MSI motherboard sucks. Too much added power for a small bump in performance. Seems like PBO2 on 5000 series Ryzen is actually worth while.

i've used both on my board having a 3800X previous to my 5800X and yes PBO2 is much better on Zen 3.

There will be None... Come On...! You could use a 9900K with a 3080/3090 and would not notice any difference from 9900K and the 5800X3D at those settings(3440 x 1440)

I'm getting distinkt K6-3 vibes from the 5800X3D. The original Athlon had the performance crown, but the K6-3 was an excellent upgrade for Socket7 boards. If you could find one that is.

The K6-3 was also a high-cache design for it's time. It had 256KB of on-die cache, something the SlotA Athlons didn't even have at the time. Further it could use the on-board L2 as L3 cache. Which was highly unusual to have at the time.
 
Don't care about OC (as in going above spec, as little that means nowadays) per se. But I want to be able to undervolt and optimize a chip that way. Hope that ability is not permanently included as collateral damage.

I believe you can use ECO Mode on all AMD CPUs weather locked or unlocked

In hindsight, the whole V-cache early announcement might have been a tactic on AMD's part to keep loyal users from jumping ship to Alder Lake.

Doubtful considering AMD fans would just wait for Zen 4, which they would certainly expect to perform at least as well as Zen 3D. Considering how long those people waited for AMD to have something remotely good, an extra 4 months between Zen 3D and Zen 4 is but the merest breath in comparison.

Maybe that logic works if Zen 3D was the first time that AMD might ever have a performance lead, but it doesn't make much sense for anyone on Zen 3 to jump ship to ADL unless they're just the type of enthusiast that always buys the best new computer regardless of how long they've had the last one. Those people aren't AMD loyalists.

Zen 3D is just the XT replacement of this generation. It's for a very niche part of the market and a bit of bragging rights. If it is king at all, it won't be for terribly long.

True, but that just changes PPT without having to touch it manually, doesn't it? Undervolting can actually improve overall performance (and that's what "OC" really is about imo).

Seen that about an hour ago however they keep talking about beta firmware. And the most recent firmware for my board is no longer beta and a full release. The beta version was 4203. I will get around to installing this bios probably on the weekend.

Version 4204 2022/03/07
PRIME X570-PRO BIOS 4204
1. Update AMD AM4 AGESA V2 PI 1.2.0.6b
2. Improve system performance and stability
3. Improve system performance for AMD Ryzen 7 5800X3D

Except that XT brought something like 3% difference. The 5800X3D will bring up to 40% better performance over 5900X in games, and some will be 0%, so let's just wait for the reviews. Bumping the clock with 100Mhz or tripling the cache size is not the same.

To be fair, where it made 0% gains with Zen3 it also was tied with Alder Lake at 0%....

Due to the low volume of CPUs that AMD expects to sell, I believe that those 5800X3D are repurposed Milan-X Chiplets, with no OC built in them, The Ryzen Pro all of them have Milan Chiplets that boost to 4.5 Ghz,

At stock on a 5800X its listed as max boost 4.7Ghz but in reality it will boost to 4.85Ghz.

So i'm wondering if we will see the same behaviour from the 5800X3D boosting to 4.65Ghz

I am not sure if AMD have set a Hard Line on the Max Boost to prevent 3D V Cache issues, but Regular Zen3 Milan processors do boost higher than their rated clock

I'd expect the hard line to be temperature related anyhow. But that's an interesting topic, nobody really did clarify or find out exactly which parameter/sensor/whatever is the actual limiting factor for the boost frequency on Zen 3, did anybody? And that might be tweaked now for Zen 3D.

These will be B2 Stepping and they should run cooler and boost higher if TDP/Temperature allows
