AMD at the data center conference in November last year, AMD announced the future EPYC processor product line, the new generation of EYPC 7004 series processors will be upgraded to the latest Zen 4 architecture, including 96-core Genoa and 128-core Bergamo.
Now someone has released a leaked photo of EPYC 7004 on Reddit. The new generation processor adopts the SP5 package, which is a very huge square. The whole processor is as big as a palm, which is much larger than the current SP4. We can’t tell from this photo whether this is Genoa or Bergamo, anyway, this must be an engineering sample of Zen 4 server processor that has not run.
EPYC 7004 processor is based on AMD’s next-generation Zen 4 architecture and is produced using TSMC’s 5nm process. Compared with the existing 7nm process, the transistor density of the new process has doubled, and the energy consumption ratio has also doubled. The performance is about 1.25 times that of the current 7nm EPYC Milan processor. It supports 12-channel DDR5 memory, up to 128 PCI-E 5.0 channels, and the CPU TDP can reach 400W.
EPYC Genoa will have up to 12 Zen 4 CCDs, up to 96 cores, and will have good single-thread and multi-thread performance for HPC, data center, enterprise, and cloud workloads. EPYC Bergamo has up to 12 Zen 4c cores, up to 128 cores. This c means that this core is specifically designed for cloud-native workloads, and some unnecessary functions have been removed to increase density. These chips use optimized cache design to respond to the increase in the number of cores, which means that the cache capacity may be reduced, and even some caches will be directly deleted. The specific information is currently not clear.
