In reality... they are committed to it as Zen signifies an architecture and Ryzen is just the series. I.E. Zen 1 is both Ryzen 1000 and Ryzen 2000 series. Zen 2 is Ryzen 3000 series and will be Ryzen 4000 (if 4 is refresh). Zen 3 will be Ryzen 5000.

THERE IS NO ESCAPE

Yeah, I don't believe the Warhol leak, saying 7nm Zen 3 next year. Remember, it is a 14-16 month cadence between chips. So a Q4 release means Zen 4 would already be Q1 to Q2 2022. If a refresh came in 2021, then that would likely push it to late 2022 to 2023.

So the refresh I'm highly doubting. If the rumor of 5nm is true, earliest for release is March to may next year for Zen 3.

But the I/O dies are made by Glofo and they don't really have anything smaller then 12nm. So maybe they wont make the I/O dies smaller. Unless they are made some place else.

There is something else they may be considering from GloFo: interposers. There is the rumor of that being used with Zen 4. It takes 32/22nm process or something like that for 2.5/3d stacking with their process. And they already do the i/o die there, which would be incorporated into an active interposer. So just a thought. One gen on 7nm for epyc, then interposer.

No. They are using 7nm and I've seen nothing saying for sure the console APUs are more than one chip, which is how they did their APUs.

This looks more and more bogus as time moves on .
very unlikely but still not totally impossible .
the rumour does appear to have gone dead though !

AMD has since come out saying Zen 3 will release this year. They said this when they said the GPU will drop before the consoles drop. So end of year we will see RDNA2 around September, the consoles drop for holiday buying, then the Zen 3 CPUs drop on 7nm. That means the rumors of already having the A0 stepping floating around were correct and they are close to final silicon for the ramp up (estimate ramp beginning 2-3 months before release). This is why a 12-15 month cadence is normal. At least 9 months from tape out to ready for ramp. Sometimes, you need a couple months of tweaking. Then you do the ramp. Intel used to stay on 12 months, then expanded closer to 15. AMD, since Zen has arrived, has consistently hit 14-16 month cadences, with Zen out in March and volume rest of the lineup in April, Zen+ in May and over the summer, Zen 2 in July and the larger chips out in October or November, and now Zen 3 out around October or November (I do not think they would wait for December as then you could drop at CES).

This means Zen 4 should arrive in December of 2021 or more likely Q1 of 2022, with CES announcement and release in February or March.

So that explains better why it went dead. AMD said otherwise on something that would contradict the potential release schedule (there is a reason I said if 5nm was used, it is a March to May 2021 release at earliest).

We've also got some rumors saying AMD did infact pick up extra 5nm supply, but it looks like it'll most likely be for GPUs rather than CPUs
