Despite the fact that AMD Ryzen 7000 desktop chips on the Zen 4 architecture will not hit the market until the second half of the year, their engineering samples have already been found in business. And they were not used to mine cryptocurrencies, but to work in a network of voluntary distributed computing.
Two AMD Family 25 series models on the Zen 4 Raphael architecture have surfaced on the MilkyWay@Home distributed computing project website, where volunteers provide their home machines to process astrophysical data. Two chip names with different OPN codes (model designations), one 8-core and one 16-core, appeared in the database:
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.
In spite of the fact that one of the positions in chip description is written as «number of processors» in reality we are speaking not about cores, but about threads. For example, opposite the 16-core Ryzen 9 5950X, 32 «CPUs» are listed in the base. Opposite the item «Cache» for both chips of the Raphael family is a value of 1024 kBytes, and this is twice as much as the L2 cache of the processors on Zen 3 Vermeer. Systems with the new chips connected to the network anonymously, and it is not quite clear for what purpose they were used in this project, because voluntary distributed computing MilkyWay@Home on the BOINC platform can hardly be called a reliable benchmark.
As a reminder, AMD Raphael processors are expected to be released in the second half of the year. They will run on the all-new AM5/LGA1718 socket with DDR5 and PCIe Gen5 support. Recently, the company also assured that AM5 platform will be supported for a long time & ; at least not less than AM4.
