ARM Neoverse

December 15, 2023

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 V-Series, ARM Neoverse N-Series, and ARM Neoverse E-Series.[1][2]

Neoverse V-Series edit

The Neoverse V-Series processors are intended for high-performance computing.

Neoverse V1 edit

Neoverse V1 (code named Zeus[3]) is derived from the Cortex-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 from TSMC. One of the changes from the X1 is that it supports SVE 2x256-bit.

According to The Next Platform, the AWS Graviton3 is based on the Neoverse V1.[7][8]

Neoverse V2 edit

Neoverse V2 (code named Demeter) is derived from the ARM Cortex-X3 and implements the ARMv9.0-A instruction set. It was officially announced by Arm on September 14, 2022.[9][10] NVIDIA Grace CPU uses Neoverse V2.[11]

Notable changes from the Neoverse V1:[12]

  • BTB capacity: 12K entries
  • TAGE predictor: 8-table
  • micro-op cache: 1536 entries (reduced for efficiency)
  • Decode width: 6
  • Rename / Dispatch width: 8
  • ROB: 320 entry
  • Execution ports: 15
  • L2 cache: 1024-2048 kB per core
  • CMN-700 mesh interconnect
    • Up to 256 cores per die
    • Up to 512MB SLC
    • Up to 4TB/s bandwidth

Neoverse V-Next edit

Neoverse V-Next, presumably V3, (code named Poseidon) was teased by Arm alongside the V2 and E2 announcements.[13] It is targeted for systems including DDR5, PCIe gen6, and CXL 3.0.

Neoverse N-Series edit

The Neoverse N-Series processors are intended for core datacenter usage.

Neoverse N1 edit

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.[14][15]

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.[16]

Neoverse N2 edit

The Neoverse N2 (code named Perseus) is derived from the Cortex-A710 and implements the ARMv9.0-A instruction set.[16] 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.[17][18][19][20] Microsoft Azure Cobalt 100 128 Core CPU uses Neoverse N2.[21]

Notable changes from the Neoverse N1:[22][23]

  • BTB capacity: 8K entries
  • micro-op cache: 1536 entries
  • Rename / Dispatch width: 5
  • ROB: 160+ entry
  • Pipeline depth: 10 cycles
  • Execution ports: 13
  • SVE2 support
  • CMN-700 mesh interconnect

Neoverse N-Next edit

Neoverse N-Next, presumably N3, was teased by Arm alongside the V2 and E2 announcements.[13] It is targeted for systems including DDR5, PCIe gen6, and CXL 3.0.

Neoverse E-Series edit

The Neoverse E-Series processors are intended for edge computing. They are designed for increased data throughput at decreased power consumption.

Neoverse E1 edit

Neoverse E1 is derived from the Cortex-A65AE[24] and implements the ARMv8.2-A instruction set. It support SMT.

Neoverse E2 edit

Neoverse E2 is derived from the Cortex-A510[13] and implements the ARMv9-A instruction set.

Neoverse E-Next edit

Neoverse E-Next, presumably E3, was teased by Arm alongside the V2 and E2 announcements.[13] It is targeted for systems including DDR5, PCIe gen6, and CXL 3.0.

Matrix multiplication theoretical performance edit

Intel 3rd Gen Xeon SP[26] 256 — 64 32
Intel 4th Gen Xeon SP[26] 2048 1024 64 32

Successors edit

With code name Poseidon a successor for Neoverse V1 (aka Zeus)[27] 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 TSMC.
