AMD official sings Zen 4 architecture! Towards a 5nm process

AT THE FAD 2020 ANALYST CONFERENCE, AMD OFFICIALLY UNVEILED A ROADMAP FOR THE FUTURE OF ZEN CPU ARCHITECTURE, INCLUDING ENTERPRISE-CLASS EPYC DRAGON AND CONSUMER RYZEN RYZEN. The AMD Zen architecture was born in 2017 and has been 14nm Zen, 12nm Zen plus 7nm Zen 2, and then we’ll see 7nm Zen 3, 5nm Zen 4, all the way to 2022.

AMD has mentioned Zen 4 on several occasions before, but this is the first time it has made it on the official road map, and it is said that there will be Zen 5.

Previously, the Zen 3 architecture on the roadmap has been labeled 7nm plus process, while TSMC 7nm process has two generations, one is the first generation 7nm DUV, the other is the upgraded version of the 7nm EUV. Since TSMC has always referred to the latter as 7nm plus, it is also natural to understand that Zen 3 will use the 7nm EUV ultra UV lithography process, and even optimistically expect to go straight to 5nm.

However, AMD has now clarified that The Zen 3 will not use the EUV Ultra UV lithography process, but will continue with the 7nm DUV, but will also be improved compared to the first generation of 7nm on Zen 2, as the specific changes will be announced later.

Of course, AMD’s original plan to use 7nm EUV on The Zen 3 was not ruled out, but the plan was not as good as the change, and it changed midway through.

In the data center enterprise market, AMD has released two generations of products, the 12nm Zen “Naples” (Naples), 7nm Zen 2 “Rome”, followed by the third generation of “Milan” will be based on 7nm Zen 3, the fourth generation “Genoa” (Genoa) Genoa) uses 5nm Zen 4.

“Napoli” was born in June 2017, “Rome” was officially released in August last year, more than two years apart, one because of the enterprise market upgrading is already slow pace, two AMD new architecture of new products just born, need the whole ecology to familiar with, to accept.

Fortunately, “Napoli” quickly gained industry recognition, “Rome” is more popular, has been adopted by a large number of top supercomputers, some even directplans on Zen 3, Zen 4.

The roadmap does not indicate a specific release date for the next two generations of products, but AMD has revealed that “Milan” will be born later this year (and not ruled out until early next year), and Genoa does not say almost but definitely by the first half of 2022.

The consumer-grade market is the Rylong, desktop and mobile release rhythm difference of about half a year, product naming is also a bit confusing, such as the current 7nm Zen 2, desktop is the Rylong 3000 series, notebook is the Rylong 4000U/H series.

AMD said that the 7nm Zen 3’s new Ryzen will also be released later this year, and the custom-first or desktop version of the Ryzen 4000 series, notebook Ryzen 5000U/H series will be up early next year to follow up, after all, the Ryzen 4000U/H series notebook has not yet been listed.

However, the rye road map is shorter, with only 7nm Zen 3 due to 2021, and the Zen 4 is not listed, but normal is certain to be later in 2022.

AMD doesn’t mention the specific performance improvements of the Zen 3 and Zen 4 architectures this time, but does it need to worry about the dazzling performance of Zen, Zen plus Zen 2?

In addition, unsurprisingly, the Zen 4 architecture will support DDR5 memory, and there is a high probability of supporting PCIe 5.0, when both The Dragon and Rylong will have to change the interface slot. An AM4 with five generations of products, nearly six years, enough conscience.
