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"

I doubt AMD is going to waste stacked dies on a 5600-level part. Really they can just cut the price if they need to, which considering that Zen 3 has been on the market for over a year now and the $50 premium that AMD added to most of the lineup, it's hard to argue that a price cut isn't in order.

Right now AMD doesn't even have anything from their latest generation in that price bracket. Even the older Zen 2 CPUs that originally released in that price range are being listed for above MSRP. The Ryzen 3100 is listed for $199 on Amazon. It's only $149 on Newegg, but out of stock there. So either Intel has enough supply to handle the crazy market demand or they're leaving a lot of money on the table pricing it below $200.

5800X3D it is: https://videocardz.com/newz/amd-con...-launches-this-spring-zen4-raphael-in-2h-2022

Other models MIA, I guess they are betting on Zen 4 instead?

@eek2121

Looks like a run on Milan-X caused AMD to divert dice to that market segment. More profit per mm2 of silicon. AMD is pushing everything to server. Everything. Desktop is left in the cold.

Yup, that is the hypothesis I had since Zen3d was put on hold on desktop and all of the H2 2021 production was diverted to Milan-X.



OTOH, good thing they are primary targeting gaming, with 5800x3d. Hopefully, it will get some high binning parts, rather than worst, as was the case with 5800x.

It will be interesting to see 5800x3d beat 5950x in gaming, to prove that those extra cores were almost useless in gaming.

It's like they are just gonna ship a few thousand CPUs and say they kept their "promise"

As far as the capacity to mass produce the stacked chips, there is not a lot of info where the capacity stands as of now and 3 months from now, but as far as TSMC investment in the packaging capacity - that is massive.

I think it is within the realm of possibilities majority of Zen 3 dies will be stacked dies sometimes in 2022.

A supply chain source from china said that there would also have 5900X3D/5950X3D in parallel with 5800X3D.

Bytheway heat/area temperature problem would be eased a bit due to new lid/package design.

You can also see a spring release as a good thing that they wait until they have enough so it wouldn't be a paper launch.
Nobody expected a January launch right?

BTW for everyone who wanted the '3DNow' label good news the edit will be easy

It should definitely be pointed out, but hey ZenX3D in year 2022.

Yeah, it's not like everything has been leaked. We'll see in half an hour.

Ryzen 5800X - 3.8/4.7GHz - TDP 105W
Ryzen 5800X3D - 3.4/4.5GHz - TDP 105W

The frequency regression also hit Ryzen-X as it did on Milan-X. There is no free lunch...

We will have to see what they are like when they are available but it is possible that is down to the limited SKU list so easing up the bining requirements is needed to optimise the yields.

I noticed this aswell.

For now since there are no models above 5800X3D alot of people on the 12 and 16 models will think twice about losing cores for cache. For me since I stayed at 8 cores. I would only be losing clock speed if I switched, so will wait for some reviews to see if its worth it.

(I seem to recall I was harshly criticized by one of the moderators for saying desktop Zen3d was put on hold.)

Hyperscalers always get first silicon from AMD. Always. It is no different with V-cache CPUs. It was never expected for any V-cache CPUs to launch before Q122 because the stacking tech didn't hit HVM until 4Q21. Milan-X still hasn't officially launched. Early samples that AMD made while bringing everything together went to key partners. That's it. Even without the supply issues and Milan-X, Ryzen CPUs with V-cache would never have launched before 2022.

I expected there to be a 5900X3D and 5950X3D at some point. The 5800X3D is most likely just the lead product. Given silicon constraints, I could be wrong, but for the exact reason you mentioned, I think AMD will bring additional SKUs. I have a 5900x at home and won't swap for an 8-core with V-cache model. I might not upgrade at all, but only way I might is if I can get a 12 or 16 core SKU with V-cache.

I hope we can now agree that Zen3d on desktop missed the window where it would have been relevant, leadership product.

By missing the window, Zen3D, and has been relegated to irrelevance...

Throwing all the bad dies at the 5800x3d is the cherry on top.

it was said that the lower frequencies are due to not wanting to go too hard on binning them, but there will be OC Potential and at clock for clock the X3D will be 20% higher IPC in gaming

It will be interesting to see how clock frequencies are effected in real world applications. The 105W base clocks don't mean much for DIY when every board by default allows for 142W sustained power use. I expect the actual clock difference between 5800x and 5800x3d will be negligible. For those willing to turn on PBO or OC with proper cooling, it won't be different at all. Obviously in any case, overall performance will be higher with the added cache.

Why? They are beating the 12900k at 4.5 Ghz,. Even the worst binned 5800X3D will be the Gaming King when compared to Alder Lake

OK just a confirmation only 5800X3D would be launched.

https://www.anandtech.com/show/17152/amd-cpus-in-2022-ces

Why only Ryzen 7, not Ryzen 5/Ryzen 9?
Because this is a new project for AMD, they want to find out how a processor like this will be welcomed into the market. A lot of users (myself included) expected AMD to go all-in with a big 16-core version, however anything Ryzen 9 requires two chiplets, and adding the extra V-Cache does require an extra cost in silicon and packaging. During a semiconductor shortage, I was told that this is the best way to get it into the hands of many people while also not in the super high-cost bracket. It also means one single unified 96 MB of L3 cache, without having to deal with two chiplets worth which might not be optimized immediately. Future versions of V-Cache on next-generation products may be expanded to other Ryzen members of the family.
