Arm Announces Neoverse V1 & N2 Infrastructure CPUs: +50% IPC, SVE Server Cores [anandtech.com]

Amazon's Graviton2 [anandtech.com] 64-core Neoverse N1 server chip is the first of what should become a wider range of designs [anandtech.com] that will be driving the Arm server ecosystem forward and actively assaulting the infrastructure CPU market share that's currently dominated by the x86 players such as Intel and AMD.

[...] Today, we're ready to take the next step towards the next generation of the Neoverse platform, not only revealing the CPU microarchitecture previously known as Zeus, but a whole new product category that goes beyond the Neoverse N-series: Introducing the new Neoverse V-series and the Neoverse V1 (Zeus), as well as a new roadmap insertion in the form of the Neoverse N2 (Perseus).

[...] In terms of generational performance uplift, it's akin to Arm throwing down the gauntlet to the competition, achieving a ground-breaking +50 IPC boost compared to Neoverse N1 that we're seeing in silicon today. The performance uplift potential here is tremendous, as this is merely a same-process ISO-frequency upgrade, and actual products based on the V1 will also in all likelihood also see additional performance gains thanks to increased frequencies through process node advancements.

If we take the conservatively clocked Graviton2 with its 2.5GHz N1 cores as a baseline, a theoretical 3GHz V1 chip would represent an 80% uplift in per-core single-threaded performance. Not only would such a performance uptick vastly exceed any current x86 competition in the server space in terms of per-core performance, it would be enough to match the current best high-performance desktop chips from AMD and Intel today (Though we have to remember it'll compete against next-gen Zen3 Milan and Sapphire Rapids products).

[...] Alongside the Neoverse V1 platform, we've seen a roadmap insertion that previously wasn't there. The Perseus design will become the Neoverse N2, and will be the effective product-positioning successor to the N1. This new CPU IP represents a 40% IPC uplift compared to the N1, however still maintains the same design philosophy of maximising performance within the lowest power and smallest area.

Neoverse V1 is basically the server-oriented equivalent of the Cortex-X1 [soylentnews.org] core, where performance is prioritized at the cost of less power efficiency and a greater die area (more cache, etc.). Neoverse N2 is more like (an unannounced successor of) Cortex-A78.
