AMD would be thinking of launching Zen3 + architecture processors
Rumors indicate that AMD would be working on the Zen3 + architecture processors, which are based on the 7nm node
Very recently it was indicated that the AMD Zen 4 architecture would take an IPC jump of more than 20%. This architecture would be, in theory, the one used in the next processors of the company. New rumors indicate that before we make the leap to the 5nm node, we will still have a new generation of 7nm processors. It seems that the AMD Zen3 + @ 7nm architecture will arrive at the end of the year.
AMD would launch Zen3 + architecture processors before making the jump to 5nm
Two scenarios are being considered. The first is that we see a optimized version of current Ryzen 5000 as it will happen with the Ryzen 3000 XT. AMD released three processors optimized a little more frequently months ago. The other option is for it to be a transition architecture towards the 5nm node. It could be that TSMC does not have its 5nm node ready to be able to produce at a good rate.
The new Zen3 + architecture would not be a great contribution, obtaining a slight performance improvement. By continuing to rely on TSMC's 7nm lithography, the performance improvement is estimated to be 7%. But there are other considerations to take into account.
It would be normal for AMD to offer processors with support for DDR5 RAM and the PCIe 5.0 interface. Due to these the company should switch to socket AM5, since the current socket would not support the new RAM, especially. It would be starting a new socket with a stepped step, not all at once.
On the other hand, it would be possible that AMD did not integrate support for DDR5 and PCIe 5.0 in the Zen3 + architecture. This would mean holding the same socket a little longer. Although at the moment it is too early for speculations, since AMD has never talked about Zen3 +. We are still going around a range of processors that never comes into being.
