Engineering:ARM Neoverse
The ARM Neoverse is a group of 64-bit ARM processor cores licensed by Arm Holdings. The cores are intended for datacenter, edge computing, and high-performance computing use. The group consists of ARM Neoverse N1, ARM Neoverse E1, ARM Neoverse V1, and ARM Neoverse N2 as of 2022.[1][2]
Neoverse N-Series
The Neoverse N-Series processors are intended for core datacenter usage.
Neoverse N1
On February 20, 2019, Arm announced the Neoverse N1 microarchitecture (code named Ares) derived from the Cortex-A76 redesigned for infrastructure/server applications. The reference design supports up to 64 or 128 Neoverse N1 cores.[3][4]
Notable changes from the Cortex-A76:
- Coherent I-cache and D-cache with 4-cycle LD-use
- L2 cache: 512–1024 kB per core
- Mesh interconnect instead of 1–4 cores per cluster
Neoverse N1 implements the ARMv8.2-A instruction set.
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.[5]
Neoverse N2
The Neoverse N2 (code named Perseus) is derived from the Cortex-A710 and implements the ARMv9.0-A instruction set.[6]
Neoverse E-Series
The Neoverse E-Series processors are intended for edge computing. They are designed for increased data throughput at decreased power consumption.
Neoverse E1
Neoverse E1 is derived from the Cortex-A65AE[7] and implements the ARMv8.2-A instruction set. It support SMT.
Neoverse V-Series
The Neoverse V-Series processors are intended for very high performance computing.
Neoverse V1
Neoverse V1 (code named Zeus[8]) is derived from the Cortex-X1[9] and implements the ARMv8.4-A instruction set. It is said to be initially realized with a 7 nm process from TSMC.
According to The Next Platform, the AWS Graviton3 is based on the Neoverse V1.[10]
Neoverse V2
Neoverse V2 (code named Demeter} was officially announced by Arm on September 14, 2022.[11]
Successors
With code name Poseidon a successor for Neoverse V1 (aka Zeus)[12] 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. Its initial realization process is said to be 5 nm by TMSC.
