For the future Zen 4 architecture, AMD has also publicly confirmed many times that it is in the process of design, the process is uncertain, and there is a high probability that it will advance to TSMC 5 nm.
Mark papermaster, amd CTO, recently confirmed in a tubing video that the Zen 4 and Zen 5 architectures are being designed and developed by two independent teams, which is the first official recognition of Zen 5 by AMD.
The 7nm Zen 3 architecture will undoubtedly be the fourth generation Ruilong 4000 series on the consumer side, and the data center end will be the third generation Xiaolong codenamed "Milan" (Milan).
According to the information disclosed in the latest road map,The third generation of Milan Xiaolong has completed the streaming film in the second quarter of this year and is expected to be officially released in the third quarter of 2020.
Its basic specification is very similar to that of the current Rome second generation Xiaolong.It is also the DDR4 memory, PCIe 4.0 bus and SP3 encapsulation interface. It continues to maintain platform compatibility, and seems to focus on architecture optimization and performance improvement.
The next four generations of Zen4 architecture, named``Genoa'' (Geneva), will not be released until 2022, but waiting is worth waiting. At that time, a new SP5 platform will be seen, while the specific specifications are still in definition, but DDR5 memory, PCIe 5.0 bus will almost certainly be seen, and there should be more advanced InfinityFabric interconnect bus.
According to the current law, the Zen 5 architecture of the five generations of Xiaolong is basically locked in 2023.
As a result, between the Zen 3 / 4 architecture in 2021, at least the data center platform AMD has no new product. On the one hand, the design of the new platform will certainly take more time and effort, on the other hand, the old platform will have to maintain a long enough life cycle, which is more obvious in the field of data center.
In terms of competition, evenIf you can catch up with or even overtake in 2021, AMD will not be too anxious because of the rivers and mountains that have been laid down in recent years, not to mention the fact that the latter Zen 4 is definitely a super move.
In addition, Zen 5 may not be the last battle of Zen architecture.Maybe there will be Zen 6.. Even by the end of Zen 5, the successful architecture will last for five generations, at least six years, and live a long life.
