Neoverse N2 (codename "Perseus") is the successor to Neoverse N1 (Ares), a high-performance ARM microarchitecture designed by ARM Holdings for the server market.
This microarchitecture is designed as a synthesizable IP core and is sold to other semiconductor companies to be implemented in their own chips.
Contents
History[edit]
Ares was first announced by Drew Henry, Arm’s SVP and GM of Infrastructure Business Unit, at his TechCon 2018 keynote.
Release Dates[edit]
Neoverse N2 is expected to show up in products around 2020. It was officially announced by Arm on September 22, 2020.
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.
Process Technology[edit]
Neoverse N2 specifically designed takes advantage of the power and area advantages of the 7nm+ process.

Architecture[edit]
The Neoverse N2 (codename "Perseus") is derived from the Cortex-A710 and implements the ARMv9.0-A instruction set.
Key changes from Neoverse N1[edit]
- ARMv9.0-A instruction set (from ARMv8.2-A)
- 7nm+ process (from 7nm)
- CMN-700 mesh interconnect (from CMN-600)
- 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
