Some early rumours coming in; this one not too major but it looks like OpenSil is nearing ready for deployment and Zen6 will be the Ryzen range to use OpenSil, before Agesa is completely dropped

AMD Preps Replacement of AGESA With openSIL Starting Next-Gen Zen 6 "Ryzen & EPYC" Families

AMD shows its plans for replacing AGESA with openSIL on the upcoming Zen 6 processors, which will allow users to contribuute or audit.

AMD Reveals Latest Plans For Open-Source openSIL With Replacing AGESA, Zen 6 Milestone - Phoronix

The big question is whether Zen6 will be on AM5. I don't think it will be. AMD will continue to 'support' AM5 for a few more years by releasing 'new' Zen 5 CPU's, with different amount of cores and x3d cache IMO.

I mean last rumours were Zen6 on AM5 due the it going onto 2027 with the latest info noted.

AMD commits to AM5 - Support through 2027 and beyond - OC3D

AMD plans to support their AM5 motherboard platform well into the future. Now, AMD plans to support AM5 "through 2027+".

"Support" into 2027 doesn't guarantee they get Zen6. It just means they will "support" AM5 into 2027 by releasing security patches/AGESA updates and or different clock speed/corecount/cache about versions of Zen5.

This is similar to how AM4 is still being 'supported' by AMD releasing 'new' Zen3 CPU's for AM4 a few months ago.

I think if that happened there would be a lot of upset people who bought into AM5 expecting a cycle similar to AM4 yet only getting an intel style tick tock with Zen 4 to Zen 5.

I get that but I don't see AM6 dropping to that time either. I think the 2027 is critical to when next Zen and the "and beyond" part I'd say is similar to how more zen6 chips will drop like they did either previous generation chips.

I think a big disappointment would be if a socket change had no real reason like the Intel ones. So if DDR6 is early (and AMD want to risk all by moving client to a new memory only - Alder Lake at least had DDR4 & DDR5 options) then it might make sense.

Any other reason for a new socket - even triple or quad channel or more PCIe slots - would go down very poorly I think.

DDR6-only in late 2025 or 2026 would see a near total collapse in AMD's desktop marketshare IMO and AMD should know that - but never say never!

AMD is more focused on workstation/server customers with desktop only being an afterthought so if DDR6 is ready to go then I imagine AMD would want to get EPYC on DDR6 asap.
 
I would think Zen 6 would be AM5, a new AMx platform typically features the latest DDR and PCI standards and PCI 6.0 has only just been launched and there's usually a 3 year lead time between a new standard coming out and the first consumer products being made commercially available for it (PCI 5.0 come out in 2019 but the first consumer grade motherboards to have that standard didn't hit the market until 2022). That's more then enough time to fit in Zen 6 on the current AM5 platform (probably 18 months from now).
 
If AMD add cores, bumping the RAM(DDR5) speed might not be enough to feed them. The next socket change will probably be a RAM change to help feed the cores. Zen 6 could be AM5 and AM6, lower core parts AM5, high end parts AM6. At this point, it's just speculation. I sort-of hope they add on-package RAM(16-48GB)(still have RAM slots on the board but optional), a lot of the AM5 issues seem to be RAM related.

They could always launch AM6 with pcie gen 5.0 and add pcie 6.0 later on similarly to how pcie 4.0 only arrived on AM4 with the 500 series boards and Zen 2 chips.

Technically on-package RAM could be good but it would increase the product line adding consumer cost (suppliers add cost, extra manufacturing costs, extra chance of failures). You also get tied in to a specific RAM supplier and wouldn't easily be able to take advantage of any technological improvements. Optional board RAM could work but we'd probably see something like Windows 11/12 bork performance until they figure out RAM scheduling.

In terms of gaming with 3D-vcache memory bandwidth doesn't provide the uplifts it once did. And if you're running the system in a professional capacity you wouldn't be concerned with overclocking memory.
Just increase 3D-vcache another 32Mb for single CCD chips and then release a dual 3D-vcache CCD CPU and that'll just be a monster gaming CPU for many years to come.

was running in to shout "but what about CAMM2 memory"

But its a strange place. If Zen 6 was still on AM5 socket, but to fully use it needed new motherboard/chipset/CAMM2 memory - does it still count as same socket?

I really hope that's not the case and I don't think it would be great move by AMD either.

The AM5 platform/ DDR5 has plenty of headroom left and one, so far, rather lacklustre CPU refresh on the platform would leave a lot of people very annoyed with AMD
 
they did pretty well with am4 socket. for the fans. i mean that is the original 1000 series plus the 2000, 3000 and 5000 series?? all on AM4 (i have 2400g and 5600g)
now theyre spoiled by too many refreshes? the history is:
ryzen 1, 2, 3, 4, 5...
1800x
3800x
5800x
7800x
9800x
?800x
unless you have a particular fetish for cpu's upgrading every generation is fairly superfluous. can't complain about progress though.
from the marketing and selling / revenues side:
have product - customers want to buy it, then it will hit a market saturation where sales will stagnate, then they have to refresh the products.
-some customers are caught up in the hype. others can wait and watch the madness. vendors have to clear/cycle inventories.
so, what im getting at is that why can't they design the refreshes for am5 keeping that socket for zen 6? then do a ddr6 with zen 6 refresh? i think another poster said as much above. BUT i have no idea what the micro-engineering constraints are.

and 2, 4, 8, series....
