Arm is bringing its next-gen Neoverse CSS N4 platforms to the cloud, sporting up to 128 cores per die, built on TSMC’s N3P process.
Key facts
- It’s a significant upgrade over the Neoverse CSS N2 platform, which topped out at 64 cores, 1 MB of L2 cache per core, and 64 MB of L3 cache, paired with either DDR5 or LPDDR5 and 64 PCIe 5.0/CXL
- 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
- For the reporter/O, Arm supports up to 128 lanes of PCIe 7/6 and CXL 4.0
- With 128 cores running at 3GHz and 2MB of L2 cache per core, Arm says Neoverse CSS N4 delivers twice the socket performance of Neoverse N3, 1.25x performance per watt, and 1.75x the memory bandwidth
Summary
Arm says Neoverse CSS N4 supports between eight and 128 Neoverse N4 cores, running up to 3.8 GHz. The platform supports either DDR5 or LPDDR6, and features up to 256 MB of L3 cache per die. It’s a significant upgrade over the Neoverse CSS N2 platform, which topped out at 64 cores, 1 MB of L2 cache per core, and 64 MB of L3 cache, paired with either DDR5 or LPDDR5 and 64 PCIe 5.0/CXL lanes. With 128 cores running at 3GHz and 2MB of L2 cache per core, Arm says Neoverse CSS N4 delivers twice the socket performance of Neoverse N3, 1.25x performance per watt, and 1.75x the memory bandwidth.
