AMD "Zen 4" 2021 Launch On Track as TSMC Optimistic About 5 nm
AMD's "Zen 4" CPU microarchitecture is on track for a 2021 launch as its principal foundry partner, TSMC, is optimistic about early yields of its 5 nm silicon fabrication node. TSMC supports the 5 nm product roadmaps of not just AMD, but also Apple and HiSilicon. "Zen 4" is particularly important for AMD, as it will release its next enterprise platform, codenamed "Genoa," along with the new SP5 socket. The new socket will present AMD with the opportunity to significantly change the processor's I/O, such as support for a new memory standard, a new PCIe generation, more memory channels, more PCIe lanes, etc. As early as 2019, the foundry is seeing yields of over 50 percent for the 5 nm node (possibly risk production designed to test the node), which is very encouraging for its customers.
AMD's roadmap for 2020 sees the introduction of "Zen 3" on the 7 nm EUV process (dubbed 7 nm+). AMD recently commented that the performance uplift of "Zen 3" versus "Zen 2" will be "right in line with what you would expect from an entirely new architecture." The 7 nm EUV node provides a significant 20 percent increase in transistor-density compared to the current 7 nm DUV node "Zen 2" chiplets and the company's "Navi" family of GPUs are built on. "Zen 3" could see the company do away with the CCX (quad-core CPU complex), and make chiplets monolithic blocks of CPU cores without sub-divisions. For the client-segment, 5 is a recurring number in 2021. It will see the introduction of the 5th generation Ryzen processors (5000-series), built on the 5 nm process, supporting DDR5 memory, PCI-Express gen 5, and the new AM5 client-segment CPU socket.

I think we had a great run with AM4 just like AM3+ back in the day.
For me, the forthcoming ZEN3 is the last AM4 series CPUs and from 2021-22 we will see a new one.
If for example they were to repeat such a thing with ZEN3 and 2x Dual-Channel memory interfaces all connected with Infinity Fabric and the price was right. That would further mess Intel up.
That's going to be my next upgrade coupled with a RDNA2 GPU.
Agreed.
Why do i think there will be clock regression? Because of this (skip to 6:51):
I really suggest the whole video.
EDIT
Somehow, trying to link the video directly @ the time mentioned isn't working, so i added the "skip to 6:51" bit.
Nice,
I've said it for awhile turning the chipset into kind of a high frequency single thread driven or just a low power energy saving co-processor CPU would be really great. I really think eliminating the chipset itself and going dual socket would be outstanding though. I think if you with with SO-DIMM's and remove the chipset a dual socket ATX board today of the past from like a decade or two back would be similar to today's ATX AM4 Ryzen MB's because the SO-DIMM's consolidates a bit of space along with eliminating the chipset does as well between the two it should be roughly the same PCB space. I know a socket occupies more space than a chipset, but by consolidating the the DIMM slot space and re-purposing the chipset space it would it would balance out roughly equivalent.
On the serious, I'd like to see what both camps have to offer when the time comes. Eggs in one basket and all.
