At the 2022 financial analysts' conference, amd finally released a new CPU roadmap, officially confirming the Zen 5 family. As planned, the Zen 4 architecture will include Zen 4, Zen 4 v-cache (3D cache version) and Zen 4C (cloud computing load optimization). At present, Zen 4 and Zen 4 v-cache are ready.
Access:
Similar to the current 6nm product launched by Zen 3 in the later stage (Reebok 6000 APU), Zen 4 will also have 4nm iterations in the future.
As for Zen 5, it is also divided into Zen 5, Zen 5 v-cache and Zen 5C, with 4nm in the initial stage and 3nm in the later stage. In terms of time rhythm, Zen 5 will be updated and launched in 2024**
Regarding the details of Zen 5, amd introduced that it adopted a new microarchitecture kernel to amplify the performance of full load scenarios, with better energy efficiency. In terms of details, the front-end pipeline and launch width are redesigned this time, and the support for AI and machine learning is further integrated (it is expected to be at the instruction set level).
It is worth mentioning that, according to the previous statement, the processor corresponding to Zen 4C will be epyc Bergamo (Bergamo, Italian port), which will be shipped in the first half of 2023, with a maximum of 128 cores and a performance increase of more than 25%.
