Prior to this, AMD's CPU roadmap was announced to the Zen3 generation, including the improved 12nm Zen+ architecture. The 14nm Zen architecture and 12nm Zen+ architecture have been released and will be officially launched at the Taipei Computer Show at the end of this month. The 7nm Zen2 architecture of the Ruilong 3000 series processor was released. At the end of November last year, the EPYC Xiaolong version of the 7nm Zen2 processor was announced.
The Zen 2 architecture is currently in production, and then the Zen3 architecture is progressing smoothly, in line with official expectations, but apart from the 7nm+ process, we currently know little about the Zen3 architecture. After the core number continues to expand to 64 cores, Zen 3 architecture should not increase the core / thread, and the main improvement of the 7nm + process is not performance, so the Zen3 architecture should be an optimized version of the Zen2 architecture.
After the Zen3 architecture? Since the name Zen4 is not very auspicious in Asia and China, there have been rumors that AMD will skip this name and enter the Zen5 era directly. However, AMD has denied that the Zen4 architecture will still exist and is under development.
In this month's investor report, AMD updated a new round of CPU roadmaps, confirming the existence of the Zen4 architecture in the official report for the first time, but AMD only mentioned that the Zen4 architecture is still in design, and other information is not available.
Considering that the Zen3 architecture will be available in 2020, the Zen4 architecture is at least 2021. At least two years ago, when TSMC's 5nm EUV process is also in mass production, the Zen4 architecture is likely to be based on the 5nm EUV process. of.
Considering the progress of Intel's technology, the 14nm processor will still be the leader in 2020, and the 10nm process in 2021. The 7nm EUV process is still rumored. Intel is likely to fall behind two generations in the process.
