AMD Zen 4 CPUs to Feature up to 128 Cores and 256 Threads, 12 Channel DDR5-5200 Memory [Rumor]

According to the latest Chiphell rumors, AMD’s next-gen Zen 4 processors will feature up to 128 cores and 256 threads in the server/HPC space with support for 12-channel DDR5-5200 memory. Make sure to take this with a grain of salt though, as many prominent sources have indicated that AMD’s 4th Gen Epyc Genoa lineup will top out at 96 cores. It is, however, possible that we may see a third CPU stack aimed at the HPC space with an even higher compute density.

This would mean that while the mainstream Genoa server processors will feature up to 12 CCDs with up to 8 cores each, this particular variant will include an impressive 16 CCDs, twice as much as Rome and Milan both of which top out at 8, eight-core CCDs. Considering that Zen 4 will leverage TSMC’s advanced 5nm EUV process, it’s not completely out of the question.

In addition to this, Zen 4-based Epyc processors are expected to feature 12-channel DDR5-5200 memory and even PCIe 5.0 support, while the consumer-grade Ryzen chips remain limited to PCIe 4.0. It has also been hinted by many reliable sources that Zen 4 will come with support for AVX512 and BF16 which have been some of Intel’s key marketing points against AMD in the server and data center space.
