Digitimes drops the bomb: the Ryzen 4000 will be at 5nm


In our news, you have often read that the new Team Red CPUs, the Ryzen 4000 (based on the Zen 3 architecture), would have been produced with TSMC’s 7nm EUV. According to DigiTimes, however, things are different. Apparently, AMD would have decided to abandon TSMC’s 7nm EUV in favor of 5nm + from the same foundry.

The news dates back to a few hours ago; the RetiredEngineer Twitter profile appeared on DigiTimes report in question, which the user has kindly translated into English and which we report below:

We start from an assumption, this is an indiscretion, so it is early to reach conclusions; one also wonders if TSMC can really produce all the chips required by AMD with the 5nm node. Yes, on paper it is plausible. As stated on the official page of the famous foundry in Taiwan, the risk production of the aforementioned node began in 2019, and the volume production began last month.

The Covid-19 pandemic slowed the company’s plans on the 3nm production process, so it is plausible that the company focused on 5nm. If the news were true, this would mark a huge step forward in the IT sector, both on the server side and for the consumer market.

The new Zen 3 architecture should lead to a 17% increase in IPC, frequencies greater than about 200-300Mhz, a unified L3 cache for each core and an increase in computing units per chiplet. We do not know if the I / O die will also be produced at 5nm, in order to decrease latency and consumption, or if it will be produced at 7nm according to the “previous” program.

Among other things, these are the expectations for the chips made with the 7nm EUV, if the new Ryzen 4000 had a more advanced node the increase in performance will be even more marked. It is also interesting to note that, taking the indiscretion for good, Team Red seems to have decided to postpone the release of the new chips to coincide with that of the eleventh generation CPUs of the blue giant, the Rocket Lake-S.

Will it be a coincidence? We don’t know, but certainly the basis for this change of plans is there. At the moment we just have to wait for further indiscretions or official statements from the giant of Sunnyvale, what is certain, however, is that really interesting months await us regarding the world of CPUs.
