Although the desktop AMD Ryzen 7000 chips on the Zen 4 architecture will only come onto the market in the second half of the year, their engineering samples have already been found in the case. In addition, they were not used to mine cryptocurrencies, but worked on a network of voluntary distributed computers.
Two AMD Family 25 series Zen 4 Raphael models have appeared on the MilkyWay @ Home website of the MilkyWay @ Home distributed computing project, where volunteers are making their home computers available for astrophysical computing. The database contains two names of chips with different OPN codes (model designations), an 8-core and a 16-core:
- AMD Eng Sample: 100-000000665-21_N [Family 25 Model 96 Stepping 0] – 16 cores / 32 threads;
- AMD Eng Sample: 100-000000666-21_N [Family 25 Model 96 Stepping 0] – 8 cores / 16 threads.
Despite the fact that one of the positions in the description of the chips is listed as “Number of processors”, in reality we are not talking about cores but threads. Compared to the 16-core Ryzen 9 5950X, for example, 32 “processors” are listed in the database. Opposite the item “Cache”, both chips of the Raphael family have a value of 1024 kB, i.e. twice as much as the L2 cache of the processors based on Zen 3 Vermeer. Systems with new chips have anonymously connected to the network and it is not entirely clear for what purpose they were used in this project, as MilkyWay @ Home hardly describes voluntarily distributed computing on the BOINC platform as a reliable benchmark can be.
Let’s keep in mind that the AMD Raphael processors are expected to be released in the second half of the year. They will run on a brand new AM5 / LGA1718 socket with DDR5 and PCIe Gen5 support. The company recently also ensured that the AM5 platform will be supported for a long time to come – at least no less than AM4.
