If Zen 3 is this year is Zen 4 for scheduled for 2021?

AMD Zen 3 (5000 Series), rumored 17% IPC gain.

Nope, 2 8-core chiplets and an I/O die. Max core counts aren't changing anywhere on Zen 3, although it's been suggested the bottom half of the desktop stack may get a lift; predominantly 8 cores across the board with a pair of 12 cores and possibly even a pair of 16 cores.
Where did you get this? 7nm IO die isn't until Zen 4. Hell, I don't think a 12nm shrink has been rumoured. There's no real power saving or performance gain to be had, and the Zen 3 packages don't need the extra room (chiplet counts are staying the same).
mute usually like 16 months apart right, so if zen 3 comes in q4 this time year then zen 4 would be around June 2022
and that timeline sounds about right cause zen 4 is 5nm which isn't ready yet and it's also got DDR5 which also isn't ready yet and pcie5 which also isn't ready yet

Go back to September 2019 in this discussion. Uploaded a video of a live AMD presentation to developers, has numerous details including the CCX removal etc.
Soldato
You've already been wrong about the CCX/CCD stuff where I pointed it out before as there will still be CCX in the next chips. I even linked the explanation which you never responded too.
You are also wrong in regards to the I/O going to 7nm. It's not, from all discussion for Zen3 they are going 12nm just like current.
Soldato
Why you refuse to watch the own's AMD video?

Post a link, this discussion doesn't go back further than December.
We might see another round of AM5 chips if that’s the case.
Soldato
I don't but I've not seen and cannot locate it, a link to it or anyone in reference in terms of articles. What I have found is reference etc is AMD saying they will utilise 12nm for I/O.
With that the CCX/CCD you are just plain wrong as you cannot produce a 12 or 16 core chip without 2 CCX to make a single CCD. They are just larger CCX with 8 core and a single 32mb cache. Instead of 2 4 core with 16mb cache for each to make up a CCX.
That has also been covered in all the articles you can Google.
Edit: there was an investors relation in September which you can download the slides they discussed in reference and there was nothing there. Can't even find what you are on about still.
There was the Epyc horizon event. That was well about Epyc. It also didn't cover any of what you are saying.

Probably not given how the Zen release schedule is slightly lengthening every generation. Zen 2 was largely July last year, Zen 3 desktop is unlikely to be here until end of the year now at the earliest because of Covid. 14 months after Zen 2 would've brought us to September anyway. 14 months on for Zen 4 brings us near the end of Q1 2022 anyway.
Even if Covid didn't happen there wouldn't have been much of a time gap between Zen 3 and Zen 4 anyway.

I imagine the first gen AM5 parts will just be a DDR5 respin of the Zen 3 AM4 parts with little other changes.

Shame not to see PCIE 5.0 just to get it all lined up. Xeon is scheduled for PCIE 5.0 in 2021 so would have been interesting to get it into mainstream for 2022. I know it's really not needed but would just be great to see it all in one package. I am already trying best to hold out upgrading PC till then but after 7 years my system is really feeling long in the tooth these days.

More reason to get Zen 3 and skip Zen 4 then

doh - confused myself - meant Zen 3 obviously
Soldato
Yeah i missed that too but still may as well skip the first AM5 CPU if that turns out truedoh - confused myself - meant Zen 3 obviously
Im not sure. Zen4 will be 5nm and that will probably open up many options.
It was a typo in my post and should have been another round of AM4 if AM5 is 2022
Soldato
I don't think there's actually enough time between Zen 3 and Zen 4 to warrant it.
I think it possible. Depending on what part of 2022.

Zen 3 desktop Q1 2021, Zen 4 desktop Q2 2022, the 14 month or so gap we've been seeing for the past few years (plus Covid's delays) would indicate this being likely. At a push Zen 4 could land July 2022.
Plus I don't think there's much in Zen 3 to warrant a "+" refresh. There was some low-hanging fruit AMD could grab with Zen 1 with some tweaks and the 12nm shrink, but what could there be with Zen 3? It's already an evolution of Zen 2, so what more could be tweaked? Maybe 10 core chiplets I guess since it's rumoured the chiplets aren't actually smaller despite the 7nm EUV node (thermal headroom rather than increased transistor density), so 10 cores per chiplet could be an experiment in transistor density before the move to 5nm. The 7nm I/O could come to a Zen 3 refresh to trial it too before Zen 4.
Baseless speculation but I think if Zen 4 desktop is any later than July 2022 it's because of problems, not roadmap.
