ARM announces Neoverse V1, N2 platforms & CPUs, CMN-700 Mesh: More performance, more cores, more flexibility

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. 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. The big promise of the V1 is its extremely large performance jump over the N1, coming in at an IPC increase of +50%. This sounds large, and it is, but it’s also not all that surprising given that the microarchitecture essentially is 2 microarchitecture design generations newer than the N1, even through from a infrastructure product standpoint it’s only one generation newer.

Architecturally, the N2 is a newer core than the V1 and takes a higher architectural baseline as the foundation of its capabilities. It’s Arm’s first disclosed Armv9 capable core, including important new features such as SVE2. The company states that the new design should still achieve an impressive +40% increase in IPC compared to the Neoverse N1, which is actually substantial given the fact that we’re promised only a linear increase in power and area. In terms of the memory capabilities, we noted that Arm expects hybrid architecture designs which would employ not only many more DDR memory controllers, but also integrate HBM memory. By now most readers will be familiar with AMD’s chiplet approach, and it’s a general architecture most vendors are heading towards given the slow-down of Moore’s law. Arm’s CMN-700 also allows for designs that are eerily similar to what AMD uses today, where a system can have a central IO Hub along with auxiliary compute dies.
