AMD Cezanne ‘refresh’ codenamed Barcelo coming to Ryzen 5000 series
With the announcement of the Ryzen 5000 series, AMD made a questionable choice to mix Zen3 based Cezanne chips with Lucienne based on Zen2. The latter was more or less a Renoir silicon refresh, although the company refused to call it this way.
It seems that the next generation featuring Zen3+ will be exclusive to Ryzen 6000 series as the first Cezanne refresh codenamed Barcelo is still to be included in the 5000 series instead. This will definitely make things simpler for customers who would rather avoid interlaced product naming such as Ryzen 5000U series. The current lineup features a mix of Zen2 chips called “Lucienne” as well as Zen3 “Cezanne”.

AMD Barcelo will be taking a different path, suggests a leak from ExecutableFix. While the leaker is not yet ready to share detailed information on these APUs such as frequencies, he confirmed that Ryzen 7 5825 and Ryzen 5 PRO 5675 will both be based on Barcelo:

According to leaked roadmaps, Barcelo was is to be used in 2022 laptop designs under AMD’s low power series up to 15W TDP. The series would be offered alongside Rembrandt-U which is to feature Zen3+ microarchitecture based on 6nm process technology. The newer version of Zen3 is also to be paired with DDR5 memory technology and PCIe Gen4. Should this rumor turn out to be true, all those features might now be exclusive to the 6000 series, while Barcelo with 7nm Zen3, Vega graphics, and DDR4/PCIe Gen3 support will be part of the Ryzen 5000 series.
