Last month, there were some rumors about a possible delay of AMD's Ryzen 4000 series desktop processors due to a switch to TSMC N5P process technology. The rumor was that this node was ready earlier than expected, and that AMD had decided it was worth it to make the switch.

A new presentation for investors published on AMD's website debunks this rumor. One of the slides confirms the Zen 3 based processors will be made on 7nm. The first 5nm CPUs from AMD will use the Zen 4 architecture. AMD also confirms that RDNA 2 is made on 7nm and that RDNA 3 will be made on an unnamed, "advanced node".

According to AMD's slides (PDF), RDNA 2 will deliver a 50 percent uplift in performance/Watt. AMD's own metrics claim a similar difference between GCN and RDNA.
