TheARM Neoverse is a group of 64-bit ARM processor cores licensed byArm Holdings. The cores are intended fordatacenter,edge computing, andhigh-performance computing use. The group consists of ARM Neoverse V-Series, ARM Neoverse N-Series, and ARM Neoverse E-Series.[1][2]
The Neoverse V-Series processors are intended forhigh-performance computing.
Neoverse V1 (code namedZeus[3]) is derived from theCortex-X1[4] and implements the ARMv8.4-A instruction set and some part of ARMv8.6-A.[5] It was officially announced by Arm on September 22, 2020.[6] It is said to be initially realized with a 7 nm process fromTSMC. One of the changes from the X1 is that it supports SVE 2x256-bit.
According toThe Next Platform, theAWS Graviton3 is based on the Neoverse V1.[7][8]
Neoverse V2 (code namedDemeter) is derived from theARM Cortex-X3 and implements the ARMv9.0-A instruction set. It was officially announced by Arm on September 14, 2022.[9][10] NVIDIA Grace,[11]AWS Graviton4[12] andGoogle Axion[13] are based on the Neoverse V2.
Notable changes from the Neoverse V1:[14]
Neoverse V3 (code namedPoseidon) was teased by Arm alongside the V2 and E2 announcements.[15] It is targeted for systems includingDDR5,PCIe gen6, andCXL 3.0. The codenamePoseidon was first used for the generation succeedingZeus, now V1, and targeted for 2021 on a 5nm node.[16]
The Neoverse N-Series processors are intended for coredatacenter usage.
On February 20, 2019, Arm announced the Neoverse N1microarchitecture (code namedAres) derived from theCortex-A76 redesigned for infrastructure/server applications. The reference design supports up to 64 or 128 Neoverse N1 cores.[17][18]
Notable changes from the Cortex-A76:
Neoverse N1 implements the ARMv8.2-A instruction set.
TheAmpere Altra (2-socket 80-core) andAWS Graviton2 (64-core) CPU platforms are based on Neoverse N1 cores and were released in 2020.[19]
The Neoverse N2 (code namedPerseus) is derived from theCortex-A710 and implements the ARMv9.0-A instruction set.[19] It was officially announced by Arm on September 22, 2020.[6] On August 28, 2023, Arm announced the Neoverse CSS N2 (Genesis), a customizable CPU subsystem implementation by Arm to reduce the time to market for customers.[20][21][22][23] Microsoft Azure Cobalt 100 128 Core CPU and Alibaba Yitian 710 use Neoverse N2.[24][25]
Notable changes from the Neoverse N1:[26][27]
Neoverse N-Next, presumably N3, was teased by Arm alongside the V2 and E2 announcements.[15] It is targeted for systems includingDDR5,PCIe gen6, andCXL 3.0.
The Neoverse E-Series processors are intended foredge computing. They are designed for increased data throughput at decreased power consumption.
Neoverse E1 is derived from the Cortex-A65AE[28] and implements the ARMv8.2-A instruction set. It supportsSMT.
Neoverse E2 is derived from the Cortex-A510[15] and implements the ARMv9-A instruction set.
Neoverse E-Next, presumably E3, was teased by Arm alongside the V2 and E2 announcements.[15] It is targeted for systems includingDDR5,PCIe gen6, andCXL 3.0.

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. Its initial realization process is said to be5 nm by TSMC.
