Also, could they be the first processors designed for the AM5 CPU socket?

Will there be a higher power equivalent desktop CPU released on 6nm?

My overall impression is that AMD's schedule has been complicated by the (presumably) late / delayed launch of Zen3D desktop CPUs.

The new APUs could be the most interesting thing we find out about at CES in January, and possibly the AM5 CPU socket...

Possibly a roadmap from AMD here, would be interesting to know if it was authored by them:
https://www.overclock3d.net/news/cp..._roadmap_leaks_-_ryzen_6000_mobile_detailed/1

Seems to go into some detail, even describing the socket type of each APU product.

There's a video here, where AMD discusses a new platform in 2022, with DDR5 and PCIe 5:
https://youtu.be/yE9PsKWYYXA?t=424

He also mentions "cooler compatibility with existing AM4 coolers", which implies a desktop platform (not a mobile or 2 in 1 platform).

What's interesting is he doesn't specifically confirm a Zen 4 desktop CPU in 2022 (but does mention a Zen 4 'product' in 2022, which could just refer to the announced Genoa server CPUs).

Is Zen 3D delayed because AMD needs 6nm to compete with Alder Lake? So will ryzen 6000 desktop chips also be 6nm?

I'm thinking of telling my dad to wait until AM5 boards are available in 2022 before building a new system (previously I advised building an Alder Lake DDR5 system). Either way, it looks like the platform will support DDR5 RAM and should involve a die shrink to 6nm EUV. Seems pretty likely these boards will be compatible with Zen 4 desktop CPUs too, whenever they release.

Hopefully, AMD will clarify at CES if the CPU socket is AM5 in 2022, or something else.

Handheld console with new AMD SOC launch delayed until 4th Jan (CES date), suspicious... Link:https://overclock3d.net/news/system...system_launch_until_after_amd_s_ces_keynote/1

It does seem to imply that new APUs may soon be ready.

Release cadence is due for mobile parts, so no socket AM5, just APU's for laptops that will later be released as the desktop equivalent. Basically no speculation required.

You should also probably read the title if the article you liked, it even says mobile roadmap. :cry:
 
So far all APUs have been monoliths. In terms of risk, going DDR5-only on APU means most OEMs probably don't want to know. Maybe AMD could make an APU with both memory controllers as most OEMs would love that: new 6000s series laptops which were benchmarked with DDR5 but onto which hype they can all ride with their cheaper DDR4 parts.

Prudence calls to launch DDR5 first for Servers, Workstations and possibly some high-end desktop. For ADL, only really the i9-12900K makes sense to use with DDR5 (making it even worse value).

'Release cadence' is not due for a new desktop CPU socket sometime in 2022? This is suggested by the video, where they discuss a new platform featuring DDR5 RAM support in 2022. Sept. 2022 will be 6 years on from AM4's launch.

I posted the roadmap as an afterthought really (to at least show that mobile APUs are likely coming next year), it's not even a complete one (or likely to be from AMD themselves).

Due means now, like if you are waiting for a train and it is due, AMD will be announcing the 6000 series laptop parts at CES, just like the 4000 series was announced at CES 2020, and the 5000 at CES in 2021. So yes, release cadence, do you disagree that laptop parts aren't due?

People have already told you about the AMD video which you bashed as nothing specific in previous threads, so why the change of heart? We know that AM5 is being released later in 2022, and Zen4 will be shown at CES, even just a glimpse of what is to come later in 2022. What are you even trying to do, I don't get it, it is like you have to disagree with what data is already floating about to try and start a conversation.
 
I didn't bash the video, I said before that they were releasing a new platform, but not necessarily Zen 4 desktop in the same year, which most seemed to assume would be happening. Why bring this up now?

Whether AM5 comes releases with an improvement on Zen 3, or Zen 4, doesn't matter too much to me (just considering whether to advise building a 12th gen Intel system or not in 2022), DDR5 support and future upgrade capability is important though.

I think we will see new APUs (with RDNA2 graphics) in the first half of 2022, with a new desktop platform with DDR5 support in the 2nd half of 2022...

Ermm.. to clarify yet AGAIN he states - "RYZEN will have a new platform and some key ingredients are, DDR5, PCI Express Gen 5, and cooler compatibility with existing socket AM4 coolers."

These is only one brand in the entire AMD line up that he could be talking about, 'cause I know I can't fit a Ryzen Threadripper cooler on my AM4 board, the only thing left is AM5.
 
All we have to go on so far for the new APUs is rumour (which suggests these aren't based on Zen 4), but if true I think this increases the likelihood of new desktop CPUs based on the same Zen architecture and fabrication technology later in the year. In addition, AMD mentioned a new DDR5 platform (presumably for desktops) in 2022.

Another point in favour of a new desktop platform, is the limitation of 142W on the AM4 socket, pretty low compared to the max power output of Intel CPUs. Source here:
https://www.tomshardware.com/uk/reviews/amd-ryzen-9-5950x-5900x-zen-3-review/4

With all rumours, there's always plenty of room for doubt though...

Zen3D looks like it will be the swansong for the AM4 platform in the 1st half of 2022.

We probably don't have long to wait for details about the APUs though, so hold tight chaps.

Zen3+
6nn low power. Focused mobile parts and maybe embedded options.

Zen 3D
7nm high performance desktop to server.

I think that is likely.

Sorry but I had to quote you from you previous thread.

I kinda think some people are reading a lot into this one interview. It certainly looks like an intention to release some Zen 4 products in 2022, but nothing more. It's obvious that some of you really want Zen 4 desktop CPUs to release in 2022, I'm not trying to wind you up by suggesting that they might not :)

Also, the guy mentions a new platform in 2022, not new CPUs, so his words can be interpreted in more than 1 way. The conversation they are having is all about platforms and new technologies, some Ryzen series history and the end of socket AM4 usage, beyond 2022.

It should probably be pointed out that both men are responsible either for technical marketing at AMD or marketing more generally. They are speaking quite generally, and don't go into the specific features of planned CPUs (except for V-Cache).

I think confirmation of the details is needed before drawing a conclusion, specifically whether desktop Zen 4 CPUs will launch in 2022, or 2023. They've been clear with Zen 4 servers, so maybe there will an announcement for other Zen 4 products in the next few months.

There are some tech review websites suggesting Zen 4 desktop CPU could launch in late 2022, or early 2023, so I'm not the only one ;)

Also, what does it matter to AMD, if they launch Zen 4 desktop CPUs in Q4 2022, or Q1 2023?

Can you not make up your mind? There has been zero official information from AMD that confirms what you previously thought, so why are you flip flopping?

Zen4 on AM5 will launch in 2022, Q3 or Q4, with PCI-E 5.0 and DDR5, and 3Dvcache Zen3 is being announced at CES for launch in Q1 on AM4. The notebook parts are also due as previously mentioned, which will be based off the Zen3 architecture with improved GPU's and power efficiencies.
 
Well we seem to be in agreement on an AM5/new AMD DDR5 platform in 2022. My view has changed a bit, as I've heard more about the possibility of new APUs for release next year.
 
Yes, no reason to think they won't. They won't be 4ghz chips (limiting to 4ghz is just useful to compare products of different clock speeds, plus they don't have to commit themselves to higher clocks in advance). I think they will probably have similar clock speeds to the Ryzen 5000 series. AMD don't need a lot of cores to compete with Alder Lake in tasks like games.

8 is all Alder Lake needs, the E-Cores make only a small performance difference. The prototype Zen3D chip had 12 cores. Performance shown here:
https://cdn.mos.cms.futurecdn.net/od7uMMTWeNWpUxNzikPa5Y-970-80.png

So, I'd expect a 10-15% performance boost in in Directx12/Vulkan games, maybe less in the majority of DX11 games (maybe just 5% in some).

It's a useful upgrade for people with B550/B570 AM4 boards, lots of people don't seem willing to upgrade their whole system to DDR5/Alder Lake. Don't know about support for older AM4 chipsets though.

I think one factor maybe some have missed with Zen3D is the difficulty of adding compatibility to older boards, it's presumably difficult to update the firmware of tons of older AM4 chipsets to add support for Zen3D. If they don't get this right, the launch could be seen as a failure, so I think that's why it didn't release in 2021. It wouldn't surprise me if they have to remove support of some older (less common) CPU models.
