According to fresh sources, a new rumor is making rounds on the Internet and it states that AMD’s next-gen Threadripper and EPYC CPUs could pack up to 128 cores based on the Zen 4 architecture. We already have heard the news that team red is indeed working on its EPYC Genoa lineup of server processors which will be offering up to 96 cores and 192 threads.

The Genoa lineup will be based on the Zen 4 cores and will most probably hit the market before the Milan-X which will be utilizing the X3D chipset packaging technology. Milan-X would be based on the Zen 3 architecture.

Maybe, but not Genoa

Its also been confirmed that AMD will also introduce Ryzen Threadripper and Threadripper Pro chips based on the Zen 3 architecture. However, the latest rumor has our utmost attention. It states that AMD’s next-gen EPYC Genoa lineup would feature a maximum of 128 cores instead of 96 as previously reported.

However, for now, AMD is yet to reveal any official details about this lineup, but a few mock renders leaked previously show that the Genoa chips would house 12 CCDs with Zen 4 cores. Its also been speculated that the CPU will feature support for 12-channel DDR5-5200 memory.

But all this news is just residents of rumor hill and should not be taken seriously, for more information stay tuned.
