AMD Ryzen plans revealed, Zen5 on 4nm/3nm node announced
Today at AMD Financial Analyst Day AMD confirmed its plans for CPU architecture in the next few years.
The company confirmed today it will deploy both Zen4 and Zen5 architecture by 2024. The new CPU architecture also includes Zen4 and Zen5 equipped with V-Cache technology (interestingly, not listed as 3D).

The Zen4 architecture based on 5nm and 4nm process technology will feature three different microarchitectures: Zen4, Zen4 V-Cache and Zen4c. The company did not clarify which of those architectures will make its way to consumer products specifically.
Mark Pepermaster also confirmed that Zen4 architecture has IPC between 8% to 10%, while offering over 15%. The new architecture offer over 25% better performance per watt and 35% overall performance improvement over Zen3 architecture. This claim is based on Cinebench benchmark.
Furthermore, Pepermaster revealed that consumer Zen4 products will launch before the data-center (Genoa) series.

By 2024, AMD also plans to launch Zen5 architecture based on 4nm and 3nm process node. This architecture will also span across three sub-architectures: Zen5, Zen5 V-Cache and Zen5c.
The new architecture will see improved performance and efficiency over Zen4. It will also see further optimization in AI and MI applications. This could suggest AMD will be adding more acceleration for more numerical formats used by different AI algorithms.
