AMD Ryzen 7000 processors appear in distributed computing project
AMD has already introduced the Zen 4 architecture processor code-named Raphael at CES 2022, as well as information about the new generation AM5 platform. At the same time, AMD also confirmed that it will release Ryzen 7000 series processors in the second half of 2022, which is also the first Ryzen desktop processor to use the LGA 1718 socket.
AMD’s unreleased Ryzen 7000 series processors have now been spotted in the MilkyWay@Home database, according to BenchLeaks. The MilkyWay@Home project uses the BOINC platform to provide computing resources through volunteers to create a high-precision 3D model of the Milky Way. It looks like someone in AMD’s engineering labs might already be running the project on a Zen 4 architecture processor.
This time there are two chips. AMD Eng Sample: 100-000000665-21_N [Family 25 Model 96 Stepping 0] is 16 cores and AMD Eng Sample: 100-000000666-21_N [Family 25 Model 96 Stepping 0] is 8 cores. The CPU IDs of these chips identify AMD Raphael ES CPUs, implying early engineering samples.
Although there are not many details in the database, it shows that the L2 cache of each core of the two processors is 1MB, which is double the current 512KB. Earlier reports pointed out that the CCD used by the Ryzen 7000 series processors will have up to 16 cores, of which 8 are Priority Cores running at full speed. The remaining 8 will be cores with reduced TDP for optimized operation (LTDP), the LTDP has a combined TDP of 30W. Each pair of Priority Core and LTDP will share 1MB of L2 cache for a total of 8MB. From the perspective of the capacity of the L2 cache, it seems to be consistent with the previous rumors.
