Arm debuts next-gen semi-custom Neoverse CSS N4 ‘Falcon' platform — compute subsystem packs up to 128 cores per die on TSMC N3P

Although Arm has talked a lot about AGI, including a deep dive into the chip’s architecture at Hot Chips , we’ve yet to see real-world performance numbers. That’s not uncommon, especially among more recent Arm-based chips. For instance, we only have gen-on-gen comparisons for Microsoft’s Azure Cobalt 200 and AWS’ Graviton5. Arm has vaguely referenced performance by saying AGI offers “more than 2x the performance per rack compared to the latest x86 systems,” though those claims are based on internal estimates, not real benchmarks .

AGI is a dual-die CPU with up to 136 Neoverse V3 cores and up to 272 MB of L3 cache that can clock up to 3.7 GHz. It has the specs to match any high-end x86 design currently on the market, built on a 3nm node and packing up to 6TB of memory capacity per chip, running at up to DDR5-8800. Perhaps the biggest difference compared to AMD and Intel was Arm’s decision to include the memory and I/O on the same die as compute, which it says leads to sub-100ns memory latency.

It’s Arm’s first attempt at its own production silicon, though it’s also been positioned so far as a vehicle for the broader applications of Arm in the data center. Microsoft, Nvidia, Meta, Google Cloud, and others build custom chips based on Arm IP, which still seems to be the primary goal, even with AGI in the mix.
