It seems that while the official debut of AMD Zen5 architecture may not be happening anytime soon, there are reports of early engineering samples being tested in labs. Moore’s Law is Dead, a source known for its tech insights, has claimed to have a screenshot that showcases a Zen5 pre-release hardware running a well-known benchmark.
The CPU that was reportedly tested appears to be a powerful dual socket 64 core Zen5 EPYC processor. The system boasts an impressive 128 cores and 256 threads, which allegedly achieved a score of 123K points in the Cinebench R23 multi-core test. This performance level is approximately 15% higher than the recently tested Genoa (Zen4) CPU, and it’s also comparable to overclocked Sapphire Rapids HEDT CPUs from Intel that use Liquid Nitrogen for cooling.
According to the available information, the Zen5 engineering sample was observed running at a clock speed of up to 3.85 GHz. However, it is not yet confirmed whether this is a peak boost speed or an average speed for this particular sample. Additionally, the screenshot from Windows Task Manager indicates that the L1 cache size is 10 MB, which translates to 80 KB per core, whereas Zen4 has 64 KB per core.
Furthermore, it appears that this particular sample had 8 CCDs (Core Chiplet Dies), which would mean that each chiplet contains 8 cores. It is also mentioned that there might be a variant of the Zen5 CPU known as Turin-Dense, which could potentially feature 16 cores per chiplet.
