Arm Announces Neoverse V3 and N3 CPU Cores: Building Bigger and Moving Faster with CSS

A bit over 5 years ago, Arm announced their Neoverse initiative for server, cloud, and infrastructure CPU cores. Doubling-down on their efforts to break into the infrastructure CPU market in a big way, the company set about an ambitious multi-year plan to develop what would become a trio of CPU core lineups to address different segments of the market – ranging  from the powerful V series to the petite E series core. And while things have gone a little differently than Arm initially projected, they’re hardly in a position to complain, as the Neoverse line of CPU cores has never been as successful as it is now. Custom CPU designs based on Neoverse cores are all the rage with cloud providers, and the broader infrastructure market has seen its own surge.

Now, as the company and its customers turn towards 2024 and a compute market that is in the throes of another transformative change due to insatiable demand for AI hardware, Arm is preparing to release its next generation of Neoverse CPU core designs to its customers. And in the process, the company is reaching the culmination of the original Neoverse roadmap.

This morning the company is taking the wraps off of the V3 CPU architecture (codename Poseidon) for high-performance systems, as well as the N3 CPU architecture (codename Hermes) for balanced systems. These designs are now ready for customers to begin integrating into their own chip designs, with both the individual CPU core designs as well as the larger Neoverse Compute Subsystems (CSS) available. Between the various combinations of IP configurations, Arm is looking to offer something for everyone, and especially chip designers who are looking to integrate ready-made IP for a quick turnaround in developing their own chips.

With that said, it should be noted that today’s announcement is also a lighter one than what we’ve come to expect from previous Neoverse announcements. Arm isn’t releasing any of the deep architectural details on the new Neoverse platforms today, so while we have the high-level details on the hardware and some basic performance estimates, the underlying details on the CPU cores and their related plumbing is something Arm is keeping to themselves until a later time.
