Arm Announces Neoverse V1, N2 Platforms & CPUs, CMN-700 Mesh: More Performance, More

[harlan4096]

2020 has been an extremely successful year for Arm’s infrastructure and enterprise endeavours, as it was the year where we’ve seen fruition of the company’s “Neoverse” line of CPU microarchitectures hit the market in the form of Amazon’s new Graviton2 design as well as Ampere’s Altra server processor. Arm had first introduced the Neoverse N1 back in early 2019 and if you weren’t convinced of the Arm server promise with the Graviton2, the more powerful and super-sized Altra certainly should have turned some heads.

Inarguably the first generation of Arm servers that are truly competitive at the top end of performance, Arm is now finally achieving a goal the company has had in their sights for several years now, gaining real market share against the x86 incumbents.

Fast-forward to 2021, the Neoverse N1 design today employed in designs such as the Ampere Altra is still competitive, or beating the newest generation AMD or Intel designs – a situation that which a few years ago seemed farfetched. We recommend catching up on these important review pieces over the last 2 years to get an accurate picture of today’s market:

• Arm Announces Neoverse N1 & E1 Platforms & CPUs: Enabling A Huge Jump In Infrastructure Performance
  
• Amazon's Arm-based Graviton2 Against AMD and Intel: Comparing Cloud Compute
  
• The Ampere Altra Review: 2x 80 Cores Arm Server Performance Monster
  
• AMD 3rd Gen EPYC Milan Review: A Peak vs Per Core Performance Balance
  
• Intel 3rd Gen Xeon Scalable (Ice Lake SP) Review: Generationally Big, Competitively Small
  

Arm is very open that their main priority with the Neoverse line of products is gaining cloud footprint deployment market share, and as an example of the new-found success is an estimate into Amazon’s own AWS instance additions throughout 2020, where the new Arm-based Graviton2 is said to be the dominant hardware deployment, picking up the majority of share that’s being lost by Intel.

Looking towards 2022 and Beyond

Today, we’re pivoting towards the future and the new Neoverse V1 and Neoverse N2 generation of products. Arm had already tested the new products last September, teasing a few characteristics of the new designs, but falling short of disclosing more concrete details about the new microarchitectures.

Following last month’s announcement of the Armv9 architecture, we’re now finally ready to dive into the two new CPU microarchitectures as well as the new CMN-700 mesh network.

As presented back in September, this generation of Neoverse CPU microarchitectures differ themselves in that we’re talking about two quite different products, aimed at different goals and market segments. The Neoverse V1 represents a new line-up for Arm, with a CPU microarchitecture that is aiming itself for more HPC-like workloads and designs oriented towards such markets, while the Neoverse N2 is more of a straight-up successor to the Neoverse N1 and infrastructure and cloud deployments in the same way that the N1 sees itself today in products such as the Graviton or Altra processors.
