AMD Zen5 architecture has been gradually revealed, Moore’s Law is Dead has picked up a Zen5 EPYC processor early engineering sample lab data.
The CPU being tested here is said to be a dual 64-core Zen5 EPYC processor with 128 cores and 256 threads, or a single 64-core 128 threads, with a frequency of 3.85GHz shown.
The test platform scored 123K in the Cinebench R23 multicore test, about 15% higher than the Zen4-based Genoa processor (the world record Intel Xeon W9-3495X processor violently overclocked to 5.4GHz using liquid nitrogen was able to reach 132,484 points).
In addition, the Windows Task Manager screenshot shows an L1 cache of 10 MB, so 80 KB per core (64 KB for Zen4).
Just from this data, this ES processor has 8 CCDs and 8 cores per small chip, which means that the consumer Riptide processor is still up to 16 cores and 32 threads. In addition, it has been suggested that the line of Zen5 CPUs known as Turin-Dense will have up to 16 cores per small chip.
Not surprisingly, AMD EPYC processors based on Zen5 cores will be available next year, and consumer-oriented Zen5 processors with 600 series motherboards should still be compatible with the AM5 slots currently in use, and the same support is expected to be provided for the EPYC SP5 platform.
According to early Zen architecture developer and chip guru Jim Keller and tipster RTG’s predictions, Zen5’s IPC boost is up to 30% or 30% for a single core at the same frequency.
