“We’ve been making coherent interconnects for quite some time in different markets and have evolved from cross bar to a ring and now a mesh given the core counts that we’re at,” Senior Director Brian Jeff told reporters last week.
“The platform also includes a coherent mesh interconnect, industry-leading power efficiency, and a compact design approach for tighter integration, enabling scaling from 4- to 128-cores.” Partners have the flexibility to add accelerators or other features with their own on-chip custom silicon, he added.Īs you’d expect, Arm’s Coherent Mesh Network (CMN) is key technological asset of the N1 platform. “Going beyond raw compute performance, the Neoverse N1 platform was built from the ground up with infrastructure-class features including server-class virtualization, state-of-the-art RAS support, power and performance management, and system level profiling,” commented Drew Henry, head of Arm’s infrastructure business unit - its fastest-growing division - in a blog post.
N1 also yields a 30 percent power efficiency improvement over Cortex-A72, according to Arm. AWS’ Graviton processor, announced in November at AWS re:Invent, is based on Cosmos.Īrm reports that chips based on the N1 platform will boost integer performance by 60 percent over the Cortex-A72 Cosmos processor (measured with the industry SPEC int 2017 benchmark), overdelivering on their promise to improve performance by 30 percent year to year. The new N1 platform (previously known by the Ares codename) is the successor to Arm’s 16nm Cosmos platform, which includes the Cortex-A72, A75 and A53 CPU cores. The company’s Neoverse E1 platform, also announced, debuts as a high-efficiency throughput platform, promising a 2.7x improvement in throughput performance over previous generations. The Arm Neoverse N1 platform, the first built on the 7nm “Ares” core, scales up to 128 cores and delivers a 2.5x performance improvement on key cloud workloads, according to Arm. Since 1987 - Covering the Fastest Computers in the World and the People Who Run Themįollowing on its Neoverse roadmap announcement last October, Arm today revealed its next-gen Neoverse microarchitecture with compute and throughput-optimized silicon designs catered toward general-purpose cloud computing and edge computing.
