On February 20, 2019, Arm announced the Neoverse N1 microarchitecture (code named Ares) derived from the Cortex-A76 redesigned for infrastructure/server applications.
The Ampere Altra (2-socket 80-core) and AWS Graviton2 (64-core) CPU platforms are based on Neoverse N1 cores and were released in 2020.
They are designed for increased data throughput at decreased power consumption.
With code name Poseidon a successor for Neoverse V1 (aka Zeus)[31] was first publicly mentioned on TechCon 2018.
Actual introduction (used by third party chip designers in their products) was given in form of a rough target date of 2021.
