A rumor from twitter (@mebiuw via Videocardz) is making the rounds and contradicting the DigiTimes report from earlier today about AMD planning to skip directly top 5nm for Vermeer. While the tweet has since been deleted, it is from an account that has posted reliable leaks in the past and as such, could very well turn out to be true (historically, tweets that are deleted have a very high probability of being legitimate). By the way, mind that rumor tag and keep that lovable grain of salt handy.
MD Ryzen 5000 Series CPUs Codenamed “Warhol”: features PCIe 4, Zen 3 architecture and 7nm process
A recent report out of Taiwan caused quite the stir by stating that AMD was planning on making a surprise shift to TSMC’s 5nm+ process in time for a launch at CES 2021. Such a move would absolutely upset the semiconductor industry and change the dynamics of silicon leadership completely as well. However, one of the regular leakers has released an AMD slide that appears to show that the company’s Warhol based chips (that succeed Vermeer) are also based on 7nm with Raphael following on 5nm. If this is the case then the CES 2021 launch would probably be with 7nm chips and not 5nm.
Interestingly, not only do you learn that Warhol is the codename of the Ryzen 5000 series processors designed to succeed Vermeer but that Raphael is the codename for what I presume is the Ryzen 6000 series. It will be based on Zen 4 and feature TSMC’s 5nm process. This also confirms that AMD has no intention of stopping its aggressive strategy with regards to node shifts.
The leaker also pointed out that the design rules of N7 are not the same as N5 so a surprise shift to 5nm might actually not be possible in this short a time span:
N5 doesn’t share same desgin rules with N7P/+. Zen3 ES is N7P.
